I have my pi in an arcade cabinet, and the stick w buttons is kinda tough to play modern games, so mostly play arcade classics on it. Was thinking of buying another, but w dev mode on xbox, prob won't now.
It took a few days building, I use a pi5 w RetroPie frontend. Ipac2 for the stick/buttons controller board. Mousetrack ball is just a usb. 32" monitor. Fans, rgb, etc.
I keep chewing on an idea.... Like patched ROMs for difficult to emulate systems, like part of the emulation has already been done. Almost a half step between decompiling and native.
Kind of how they patch that out, but instead just patching out instructions. Difficult to describe.... X86 copy to ARM copy instructions, replace the instruction, but memory management would get insane....
@SylverReZ, also iirc mame didnt emulate donkey kong's sound correctly and thats why billy mitchell's gameplay in that king of kong documentary has no sound
