Over time I've amassed quite a large collection of other Linux Based SBC's many of which are capable of out performaing the Raspberry Pi, also many of which should be, but don't currently have the correct software support to fully drive the graphic or sound hardware.
There's also a fair few older and less powerful boards which don't quite match the performance, but nevertheless are still capable of being used as fun development targets.
I'll keep details of systems where I have successfuly got the games to build and run, and notes of any specific issues they presented. Also I maintain an occasional blog HERE that lists my experience with the collection.
I'll also list ones that I can't "currently" get to work, and some thoughts on why!
