Retroflag Gpi - Banana Pi Zero?
« on: August 03, 2019, 06:28:12 pm »
I am really interested in the Retroflag Gpi, because of its great price and build quality, but it only officially supports the Raspberry Pi Zero, which is not all that powerful, even for SNES games.
The Banana Pi Zero works with it, but the inputs do not register.
Anyone here have any idea how to fix that?

Hey, how's it going? I'm also pretty interested in this device and I just happened to come across this post. I think that it is possible to do what you are suggesting by using an overlay file, however, I do not know how to make it.

There is documentation for raspberry pi overlays here: https://www.raspberrypi.org/documentation/configuration/device-tree.md and for AllWinner devices (such as OrangePi) here: https://docs.armbian.com/Hardware_Allwinner_overlays/.

Looking at the AllWinner doc, it says that custom overlays are supported "experimentally". I think it may also be possible to bake it into a custom kernel if you (or someone else who owns the device) are able to build one. Sometimes if you buy a developer in the scene the hardware, they will work on it if there is enough demand. However, these gPi devices seem to be kind of hard to get a hold of, so I'm not really holding my breath.

To be clear, I am not certain that this is workable, it's just a suggestion on where to start looking for answers if you are so inclined.
