The RG350 and RG280 devices run on a Linux-based firmware called OpenDingux. This operating system was originally intended for the GCW-0 retro handheld device, which was part of a successful Kickstarter campaign back in 2013. And while this old firmware presents some advantages (like 7+ years of app development history), its kernel has become outdated over time. Luckily, developer zcrc has been working on getting the current upstream Linux onto these devices, and for about a month now there have been nightly builds of a public beta for this new firmware, which is simply called “OpenDingux” (I’ll refer to it as “OD beta” throughout this guide). To read more about its development, check out this update from this past summer.
Long story short, I’ve been following this beta release for a couple months now, and I think it’s time to say that you should consider flashing this firmware onto your device. I first touched on this beta in my Super Mario 64 guide, but at the time I didn’t see any real benefit to loading it other than to play SM64 on a device that shouldn’t really be able to play this game so dang well. But since then, the OD beta has been getting better and better, including added support for the RG280 devices.
So in this guide I’ll show you how to install the OD beta firmware, and also provide a list (with links!) to all the OPKs/apps that run on it. This guide applies to the RG350, RG350P, RG350M, RG300X, RG280M, and RG280V devices.Continue reading “OpenDingux Beta Firmware for RG350 and RG280 Devices”
