Retroid Pocket 2+ Starter Guide

Last updated: 23JAN2022 (see Changelog for details)

The Retroid Pocket 2+ is a seemingly simple device to set up — it runs Android, so how hard could it be? Well it turns out there are some orientation quirks in getting the RP2+ up and running, and so this guide is meant to take you from the very beginning of your journey with the device and take you to the point of being a superstar.

I’ll be updating this guide as time marches on, so be sure to check back frequently as I add more updates and tweaks.

Sandisk (left) and Samsung (right) microSD cards

The RP2+ will not come bundled with a microSD card. I recommend using a card from reputable brands like SanDisk or Samsung to use in your device.

In general, I recommend the cards listed below, in order or preference. The prices fluctuate all the time, so keep an eye out for deals. In general, I would expect to pay $20 for a 128GB card, $30 for a 256GB card, and $60 for a 512GB. A 128GB card will allow you to load EVERY 8-bit and 16-bit game out there, just all of the arcade games that work, and quite a few PS1, Dreamcast, PSP, GameCube, PS2, and Sega CD games (those systems have the largest file sizes). A 256GB or 512GB card will allow you to store even more of those larger games. You can use a larger card than these but then you’ll have a card that costs more than the device itself, and are you really going to play more than 512GB of games at once?

128GB cards:
SanDisk Extreme
Samsung EVO Select
SanDisk Ultra

256GB cards:
Samsung EVO Select
SanDisk Ultra

512GB cards:
Samsung Evo Select
SanDisk Ultra

Another accessory to consider: if you don’t have a nice microSD to USB adapter, you might want to think about getting one. A nice adapter like this one from Anker will give you the fastest transfer speeds possible, and won’t cause any corruption issues with your card.

Additionally, the Retroid Pocket 2+ doubles as a pseudo home console, thanks to its HDMI output function as well as the ability to connect to controllers via bluetooth or USB. The HDMI adapter is smaller than the standard size, so you will either want to grab a micro HDMI cable like this one from Amazon Basics, or a micro HDMI adapter to use with an existing cable.

Speaking of controllers, there are plenty of options out there, but I prefer to use something that’s somewhat retro-friendly. You could use a bluetooth controller like the 8BitDo SN30 Pro, or a wired controller like the Betop BD2E. Note that in order to use a USB controller, you will also need an OTG adapter to plug the controller into the device’s USB-C port (you could also use a USB hub to plug in multiple controllers at once!).

Prepare your ROM library

Since the Retroid Pocket 2+ takes a while to ship, I would recommend that you build your ROM library now, if you haven’t already. When actually playing games, we’re going to use a combination of RetroArch (for lower-end systems) and standalone emulators. The chart you see above is a preliminary list of accepted file types in the Retroid Launcher frontend application, so I recommend grabbing ROM files within those file types — many emulators can play more than just these file types, but if the Launcher cannot recognize them, you’ll be out of luck using that frontend.

Here is a general list of systems that can be played on the Retroid Pocket 2+. Those noted with an asterix cannot play every game at full speed, and so performance may vary. For PS2 and GameCube, I recommend getting PAL region ROMs, because they cap out at 50Hz which will give you better performance than struggling to reach the standard 60Hz found in NTSC region ROMs. ROM file sources will not be shared on this website.

When getting ROM files, I recommend using the “No-Intro” naming convention, which is the standard naming used for ROM sets within RetroArch and other emulation communities. By using no-intro naming, you will be more likely to get box art automatically added when you load up your games in the Retroid Launcher or other similar frontends. If you have a question as to how a game should be named, I recommend checking out the Libretro thumbnails directory, which is what many emulators pull from for their media files. If your game name matches the thumbnail name found in this directory, chances are that it will properly download the media for it.

Additionally, an important component of a ROM library is maintaining BIOS files. BIOS files are system files necessary for some emulators (GBA, Sega CD, or PS1/PS2), and are helpful in improving accuracy with other systems. These files are copyrighted so you are on your own to find them, but a quick search for a RetroArch bios pack should get you on your way. Note that PS2 BIOS files can be easily dumped from your PS2, or you will need to find them elsewhere. Here is more information about BIOS files.

Here is a list of recommended BIOS files for maximum gaming fun:

SEGA CD:
bios_CD_E.bin
bios_CD_J.bin
bios_CD_U.bin

Initial setup and orientation

When it comes to initial setup, I recommend watching the video above. In this video I’ll walk you through how to navigate the Setup Wizard. One important note is to update your device as soon as you get it, and to NOT install your pre-installable apps until after you’ve updated. This will give you the most performant version of Dolphin for ideal GameCube performance.

After it’s set up, you can jump into the Google Play Store app and start downloading emulators and games. Here are some recommended apps that I think are worth grabbing from the Play Store to get you started. Note that those highlighted in light blue boxes are already pre-installable on the RP2+. The apps in orange can be found in the Play Store, and some may cost money.

Recommended emulators:
DraStic (Nintendo DS)
AetherSX2 (PlayStation 2)
Yabasanshiro 2 Pro (Saturn)

Recommended streaming apps:
NVIDIA GeForce Now (PC & cloud streaming)
AMD Link (PC streaming)
Parsec (PC streaming)
Google Stadia (cloud gaming)
PSPlay (PS4 & PS5 remote play)
Xbox or Xbox beta (Xbox One/Series remote play)

Recommended Android games:
Stardew Valley
Dead Cells
Terraria
Minecraft
Grand Theft Auto III (and its sequels)
Max Payne
Horizon Chase
Oceanhorn
Forager

Portable versus Internal storage: When you plug in the SD card, you may get prompted to “set the SD card up”. It will ask you to choose between the default portable storage option, or using the card as internal storage. Portable storage means that you will be able to freely take the SD card out of the device and plug it into your PC, as demonstrated in the video above. If you set it to internal storage, you will then be able to install apps on the SD card to save space, but you won’t be able to plug the SD card into your PC — instead, you will have to plug the device into the PC and transfer files via USB instead. Internal storage is a good solution if you want to install a LOT of Android games onto your device, but in general I recommend portable storage for its flexibility.

One other note to make: plugging the SD card directly into your PC to transfer files will give you much greater transfer speeds, about 4x the speed of USB file transfers. So I recommend removing the SD card and plugging it into your computer whenever you have a large batch of files to transfer; USB transfer works fine in a pinch for smaller transfers.

Controller style: By default, the Retroid Pocket 2+ uses Nintendo-style controls for its buttons (where the A/confirm button is on the right, and the B/cancel button on the bottom). As such, most apps will invert the controls and you will need to go into the settings and remap the controls. A good example is Dead Cells, which I reconfigure in my Retroid Pocket 2+ Starter Guide Part 2 video. All of the settings tweaks done in my two videos are done under the assumption that you are leaving those controls as standard. If you want, you can actually change your controller style in the settings so that they mirror Xbox-style controls (where the confirm button in the bottom button, and the cancel button is on the right). To do so, go into Settings > Handheld Settings > Input > Controller Style and set it to Xbox instead of Retro. This means you likely won’t have to make any other options or remapping tweaks in your apps.

Sleep mode: The Retroid Pocket 2+ can enter sleep mode by tapping the POWER button, much like a tablet or phone. And like with a tablet or phone, you could simply leave this device in sleep mode when not using it, and it will slowly discharge over the period of a week or two. However, if you are playing the device frequently (like every day or a few times a week), I recommend just keeping it in sleep mode and charging it as needed, like you would a phone. Powering on the device takes quite a bit of time (about 40 seconds), which can add up if you play the device often. When not using the device for an extended period of time, be sure to fully power it down (and recharge the battery every few months).

Retro Handhelds community RP2+ compatibility spreadsheet

One of the greatest resources of the Retroid Pocket 2+ is the fact that it is a popular handheld device with a large community surrounding it. This gives you the ability to leverage the talent and time of other community members to find the best tweaks and settings for each of your games. A great example is the Retro Handhelds community RP2+ compatibility spreadsheet. This spreadsheet will show different tabs for the most popular systems, and will include a list of games that have been tested and recommended tweaks.

One important note is to download their MMJR2 community configuration files, which will work with the Dolphin emulator to give you the best performance.

Recommended RetroArch hotkeys for the RP2+

Setting up RetroArch

Be sure to check out the video above for tips on how to get RetroArch up and running, and to integrate it into your Retroid Launcher. You will also need to map your keys initially so that the A/B and X/Y buttons are not swapped while in-game. Additionally, the table above will show you my recommended hotkeys for the easiest gameplay experience when using RetroArch-based emulation like for classic systems (Game Boy through Super Nintendo).

RetroArch config file: For those of you who know your way around RetroArch and want an easier solution, here is a copy of my retroarch.cfg file which will have all of the system-wide configurations baked in. So hotkeys, scaling and resolution, and so on will work out of the box. Place this file in the Android > data > com.retroarch.aarch64 > files folder found within your RP2+ internal storage. Note that you will still need to set up console-specific overrides, like rewind support for NES, etc.

Other system-wide RetroArch settings I recommend for the RP2+:

Menu driver: XMB
Menu scale factor: 1.50x
Video integer scaling: OFF
Video scaling: Core Provided
Video filter: Normal 2x
Auto Save State: ON
Load State Automatically: ON
Display Overlay: OFF

Per-system recommendations

These per-system recommendations will be covered in the starter guide videos, but here are some quick notes for reference.

Game Boy / Game Boy Color
Emulator: RetroArch (Gambatte core)
Filter: Normal 2x
Rewind Support: ON
Colorization: Internal / Special 1
Interframe Blending: LCD Ghosting (Accurate)

Game Boy Advance
Emulator: RetroArch (mGBA core)
Filter: Normal 2x
Rewind Support: ON

Nintendo Entertainment System
Emulator: RetroArch (FCEUmm core)
Filter: Normal 2x
Rewind Support: ON
Run-Ahead: ON (1)

Super Nintendo Entertainment System
Emulator: RetroArch (Snes9x core)
Filter: Normal 2x
Rewind Support: ON
Run-Ahead: ON (1)

If a game experiences slowdown (for example, with Final Fantasy III or Super Mario RPG), then toggle off Rewind Support or Run-Ahead for performance improvements. RPGs in particular generally won’t benefit from those two settings anyway. 99% of games should run at top speed with the above settings.

Sega Genesis and Sega CD
Emulator: RetroArch (Genesis Plus GX core)
Filter: Normal 2x
Rewind Support: ON
Run-Ahead: OFF (causes jittery gameplay when ON)

Notes: The Retroid Launcher frontend currently does not have Genesis/CD/32X listed as a possible option. If you want to use the Retroid Launcher as your primary launcher but still want to play Genesis games, I recommend setting up RetroArch playlists.

Sega CD games will require BIOS files to run correctly, and they are listed in the BIOS section above.

TurboGrafx-16 (PC Engine) / TurboGrafx-CD (PC Engine CD)
Emulator: RetroArch (PCE Beetle Fast)
Filter: OFF (remove the Normal 2x filter and then do a core override)
Rewind Support: OFF
Run-Ahead: OFF

TG-CD and PCE-CD games will require BIOS files to run correctly, and they are listed in the BIOS section above. Like with Sega Genesis, there is no TG-CD or PCE-CD section in the Retroid Launcher, so your best bet is to use RetroArch playlists.

Sony PlayStation
Emulator: RetroArch (PCSX ReARMed core)
Filter: OFF (remove the Normal 2x filter and then do a core override)
Rewind Support: OFF
Run-Ahead: OFF

Emulator: DuckStation standalone
Enhancements: 2x resolution (may cause slowdown with some games)
PGXP Geometry Correction: ON (may cause slowdown with some games)
Controller Type: Analog Controller
Use Analog Sticks for D-Pad in Digital Mode: ON

Notes: Sony Playstation games will all play on the RetroArch core without issue, but you can also use the standalone Duckstation emulator, which is more accurate and will allow you to use 2x resolution in many games. Adding geometry correction will further enhance the visuals, but come with another performance cost.

See the Starter Guide video 2 for configuring analog controls in RetroArch; note that after making the video I found a way to force analog controls in all PS1 games with DuckStation, and those options are now listed above.

The 32-bit version of RetroArch actually works best with PlayStation 1, because the PCSX ReARMed core that comes with it allows for 2x resolution (“enhanced resolution”) while maintaining excellent performance. However, this version of RetroArch is currently not working with the Retroid Launcher. So you can use RetroArch’s playlist function to launch your games, or modify the apk’s androidmanifest.xml file and replace any instances of package name “com.retroarch.ra32” to “com.retroarch” to trick the launcher into booting the 32-bit version instead.

Nintendo 64
Emulator: Mupen64Plus-FZ

The version of Mupen64Plus-FZ that ships with the RP2+ has been updated by the developer specifically for this system. To get these updates, you will want to uninstall the version of the app that comes with the device, and then install the Google Play Store version instead.

The developer of Mupen64Plus-FZ recommends creating this default emulation profile specific to the Retroid Pocket 2+.

  • In the left menu bar, select Profiles > Emulation
  • Select the GlideN64-Very-Accurate profile and then Copy. Give it a unique name, like “Chicken”.
  • Make the following changes in the profile:
    • Use Faster Shaders > ON
    • Use Native Resolution Factor > 1x
  • Next, in the left menu bar, select Profiles > Select Profiles > Emulation profile > Chicken. This will make your new profile the default emulation profile.
  • Finally, in the left menu bar, select Settings > Shaders and make the following changes
    • Shader scale factor > 1x
    • Shader Passes > Pass 1 > FXAA

To improve the navigation experience, go into Settings > Input > Show in-game menu > When slide gesture is used. Now, you can swipe from the left side of the screen to bring up the Mupen64 side panel when in a game, to easily save your game, exit, etc.

By default the N64 A and B buttons will be mapped to the A and X buttons on the RP2+. If you want to adjust your mappings, you will need to copy the Android Gamepad controller profile and make your own mapping (much like how we just set up the emulation profile above).

When using the Retroid Launcher, autosave and autoload will not work properly. Instead, you can either launch games directly from the standalone emulator, or use the Save/Load State functions within the emulator quick menu to manually save and load states. In-game saves still work fine either way.

The Pro version of this emulator costs $4 and will give you the ability use cloud saves and netplay. However, it won’t work with the Retroid Launcher by default. To add it to the Retroid Launcher, install the app, then add these parameters in the “Edit” section of the Retroid Launcher:

  • Name; M64Plus FZ Pro
  • Package: org.mupen64plusae.v3.fzurita.pro
  • Activity: paulscode.android.mupen64plusae.SplashActivity
  • Data type: */* (no spaces between asterix and slash)

Check the Retro Handhelds compatibility spreadsheet for recommended settings on a per-game basis.

Nintendo DS
Emulator: DraStic
Frameskip: OFF
High-Resolution Rendering: ON

Notes: I recommend using L2/R2 as your L/R buttons on the console. You will need to remap your controls, and then set up screen swap functions assigned to unused buttons (like L1/R1 or L3/R3). See the Part 2 video above for a demonstration.

In the Part 2 video above, I recommended turning the touchscreen controller opacity to 0% to hide the buttons. I later learned that this can affect touchscreen performance since the buttons are still there. Instead, start up a game and enter the Menu, then select Edit Screens and Virtual Pad. Here, choose “Landscape Aspect” > Menu > Edit Controller Layout. Go through and tap on each button and then disable them, t hen select Apply. When that is complete, select Menu > Save as global layout. Repeat this process for the “Landscape 1:1” layout as well. This will remove the buttons altogether so they don’t inhibit touchscreen gameplay.

Sega Saturn
Emulator: Yabasanshiro 2 (or Pro version to remove ads)
Frameskip: ON (default)
Rendering Resolution: Original (1x)
Sound Engine: Legacy (toggle with Modern as needed to improve performance)
Sound Time Synchronization Mode: Real Time

Notes: You will need to remap your controls. I recommend using YBA for ABC, and L1, X, R1 for XYZ buttons.

If you want the original Saturn boot video sequence, you must place the BIOS file (saturn_bios.bin) in the yabause/bios folder on your internal storage (this folder will only appear once you have opened the app at least one time).

Check the Retro Handhelds compatibility spreadsheet for recommended settings on a per-game basis.

Sega Dreamcast
Emulator: ReDream
Frameskip: ON (default)

Notes: You will need to remap your controls. Upgrading the pro version won’t do much on the RP2+ other than remove the prompt to upgrade to pro when you start up the emulator. However, it will be associated with your Google Play Store profile and can be used on other devices (like your phone) to get upgraded rendering resolution.

If you want the original Dreamcast boot video sequence, you must rename the dc_boot.bin BIOS file to boot.bin and place it in the Android/data/io.recompiled.redream/files/ folder on your SD card (this folder will only appear once you have opened the app at least one time).

Sony PSP
Emulator: PPSSPP
Graphics Backend: OpenGL (alternate with Vulkan to assess performance on games)
Internal Resolution: 2x (reduce to 1x for better performance)
Show FPS/Speed: BOTH
Touchscreen overlay: OFF
Frameskip or auto frameskip: 1x (only for games that need it)

Notes: You will need to remap the ABXY buttons. For games that don’t run at full speed, consider adding auto frameskip or dropping the internal resolution to 1x.

Check the Retro Handhelds compatibility spreadsheet for recommended settings on a per-game basis.

Nintendo GameCube
Emulator: Dolphin MMJR2
Internal resolution: .7x (reduce as needed to improve performance)

Notes: Use PAL ROMs as available. Be sure to download and install the MMJR2 community configuration files, which will work with the Dolphin emulator to give you the best performance. Place the two .ini files in the MMJR revamp/config folder in your internal storage (the app must be opened once before for this folder to appear) and replace the files that are in there already. See the Part 2 video above for a demonstration.

Check the Retro Handhelds compatibility spreadsheet for recommended settings on a per-game basis.

Sony PlayStation 2
Emulator: AetherSX2
Preset: Fast/Unstable
Enable Frame Limit: toggle OFF as needed to improve performance
EE Cycle Rate: 60% (adjust to 50% as needed)
EE Cycle Skip: Maximum Underclocking (3)

Notes: Use PAL ROMs as available. You will need to remap the buttons, and follow the instructions in the Part 2 video to toggle touchscreen controls.

Check the Retro Handhelds compatibility spreadsheet for recommended settings on a per-game basis.

Creating RetroArch playlists

In addition to using a frontend launcher (like the default Retroid Launcher), you can also set up playlists within RetroArch to browse and launch your games. This will be helpful in certain cases, like playing systems that aren’t listed in the Retroid Launcher. There are two methods for creating playlists in RetroArch:

  1. Scan Directory. This is the most straightforward way to make playlists, and is best for systems with unzipped ROMs that have distinct file types (like .nes games). With this option, you will navigate to the folder that contains your ROM files, then select “Scan this Directory”. RetroArch will then recognize and scan the directory for games, and assign the console and assets to that system. You should then see it in your playlist. When you have a more common file type for your games (like .bin files for Genesis games, it’s better to do a Manual Scan).
  2. Manual Scan. This is the preferred way to scan your directories because it gives you more control. Here is the breakdown:

Content Directory: navigate to your ROM folder and select “Scan this Directory”

System Name: select the system name you want to associate with your playlist

Custom System Name: use this if you want to use a special name for this playlist. Note that you will also need to set your “System Name” to “Custom” for this to work

Default Core: select the core you want to associate with this play list. Afterwards you can assign a different core to specific games by selecting the game and choose “Set Core Association”

File Extensions: add in all of the file extensions you want to scan for your console. You can leave this blank if they are all the same (e.g. zip files for arcade games), but for the most part it’s helpful to add these in, especially if you are using several file types. Separate each file extension with a space (no comma), like this for Dremcast: cdi, gdi, chd

Scan Recursively: turn this on if you want to scan subfolders too

Scan Inside Archives: this will scan the files within the zip file, whether you want this on will depend on the system you are scanning. You will want this off if scanning arcade games

Arcade DAT File: this is important if you are scanning arcade games, because it will associate your zip file (“simps2pj”) with a full file name (The Simpsons). To set this up, head to this page and download the latest FBNeo dat file (it works for MAME also). Then save this file somewhere that you can access on your RP2+, and choose it when at this part of the menu

Arcade DAT Filter: with this selected, only arcade games that appear in the DAT file will show up in your playlist. Generally you want this setting OFF

Overwrite Existing Playlist: this will overwrite anything already in the playlist. You generally want this OFF if you are just adding new games to your playlist

If you want thumbnails to appear next to your games, you need two things: 1) the files must be named according to the “No Intro” standard (e.g. “Super Mario Bros. 3 (USA)”) and 2) go into Online Updater > On-Demand Thumbnail Downloads > ON so that they will download when you browse through your playlist. Alternatively, you can manually scan each playlist for thumbnails in the Online Updater section instead.

30 thoughts on “Retroid Pocket 2+ Starter Guide

  1. Great to see a guide like this. I ended up cancelling my preorder of the device, but I still think it looks really cool.

    I have a question, though. Why do you recommend .iso files for PS2 and Gamecube? For PS2, .chd files and .gz compression don’t affect gameplay but shrink the file size (though for .gz, the emulator has to unpack the game the first time you play it, which means like a 20-30 second black screen on first boot up). For Gamecube, .rvz does the same thing. You can use chdman for chd files, pigz for gz, and you can compress files into .rvz using Dolphin.

    1. Hi, it’s not about what will work with the emulators, but what file types the Retroid launcher recognizes. I agree that .chd and .gz are the way to go in just about all other use cases!

  2. Great guide – thanks for the writeup!

    Is there a reason you recommend (CPU intensive) video filters over (GPU-powered) shaders? As long as you pick one or two-pass shaders, you should be able to get really nice results (including some niftier effects) without adding much CPU load. Just pick sane low-end-friendly 1 or 2-pass glsl shaders, not the crazy 5-pass CRT-with-bloom-type stuff, and you should get nice results with a lot of options to choose from.

    Like

    1. For sure, shaders can add a nice touch! But I haven’t found one that will give the same sharpness and pixel balance as the Normal2x filter — it basically normalizes the image but balances the pixel wobble at the same time. And thankfully the CPU can handle the filter for SNES and below, and so for that reason I think it’s a good fit for beginners who want nice scaling and an image that’s “true” to their expectations.

      Like

      1. I’d say the interpolation/sharp-bilinear-2x-prescale filter is very good, as is Quilez, if you’re looking for a “faithful big pixels” kind of look; I’m not sure I could pick out either from the Normal2x filter in an A/B test on a 640×480 screen at normal viewing distances. That said, if you’ve got the CPU to spare, do what looks best to you!

      1. Thanks for the great setup tutorial, this has been extremely helpful!

        One issue I’m having is the hot keys aren’t working. Be set them up the way you describe but when I try them in-game they don’t seem to work. For example, I’ve tried to access the menu to adjust the GB color settings as you describe, but when I hold SELECT and the hit key mapped to menu nothing comes up. Any thoughts?

  9. I’m using my RP2+ mostly to play N64, and I’m very confused by the way the game saves work. The guide says :

    “When using the Retroid Launcher, autosave and autoload will not work properly. Instead, you can either launch games directly from the standalone emulator, or use the Save/Load State functions within the emulator quick menu to manually save and load states. In-game saves still work fine either way. ”

    But in my experience, I’m using in-game saves and everything works fine as long as I don’t close Mupen64Plus-FZ, but whenever I initialy launch the game (either from the retroid launcher or from the app), it will look like I’ve lost all my progression. Luckily I have a save state that I can load and resume my game from but I’m only a “save state” instead of “load state” away from messing it up!

    1. Apparently this is known to happen with the specific game I’m playing (Donkey Kong 64). When using autosave/autoload or save states, the in-game save can become corrupted and once it is, there is no way around it. I guess I’ll just be extra careful when using save states and regularly export Mupen64Plus-FZ’s save data to external storage!

  10. Hi Ross,

    When you connect HDMI, it still display as 480p and it’s awful, do you know of a workaround? It doesn’t do widescreen or even higher resolution. PS4 controller doesn’t work, PS5 does however. Dead cells resolution gets all messed up when connected and can’t change any settings.

  11. Hello all! I have an unusual question I haven’t seen addressed anywhere else regarding the RP2+. Is it possible to remove system apps from the home screen? It’s not like I want to uninstall them or anything (which I don’t believe I can or even if that would wise do) but I haven’t found a way personally. The RP2+ is obviously quite different from an actual phone where this would be easy, does anyone here know of a way?

  13. Hi Russ, I initially used a Sandisk 64gb extreme card to setup the RP2+, but soon it runs low on disk space due to the large PSP games, so I upgraded to a sandisk 256gn ultra card (up to 100mb/s) by copying all the content of the 64gb over to it, but i realised that in PPSSPP, half of the psp games couldnt load in the title list on PPSSPP, may I know how do I overcome this? Is it that the new 256gb is too slow so I should get a 266gb extreme instead?

  14. Hi there!

    Has anyone gotten a USB-C hub to work for multiple wired controllers? This guide contains a link to one, but I wanted to see if anyone has had any luck actually getting it to work on the RP2+. So far, the supposedly OTG hubs that I’ve tried don’t seem to register any devices on the RP2+

    Thanks!

  15. Hi I followed your instructions on setting up new RP2+ but it seems all the gb, gba, gbc games suddenly have no sound. Appreciate it if you could advise me thanks!

  16. One thing I recommend is compressing PSP ISOs to CSO format. This will cause games to scale down to half their original sizes and as far as I’ve tested it doesn’t affect the emulation.

  17. hey! lovely review. Am new to the scene, my only question on the guide does the console change your settings per emulator for you, like after pre-setting them. or do you need o manually swap the settings each time. Thanks 🙂

  18. I was playing with it earlier and I got game boy set up and I went to set up game boy color and then all the sudden my button scheme changed and now my x and a buttons don’t work. I try to remap them on retroarch 64 but it doesn’t even register that I’m pushing the buttons
