Hi I'm looking to build my first rapsberry Pi with a recalbox. Mostly to play NeoGeo, PCE and some Md/Snes games. Somes questions :

how good is the emulation for these consoles ?

i was looking to buy a Pi4B but it doesn't supported. Should i buy a Pi3B+ instead ?

will the recalbox automatically work with a wired joystick madcatz TE ? (It works on pc)

Thanks !
