I just have one question regarding the original topic of this thread. How is handling input faster than the original hardware allowed, not considered to be a "cheat"? The original programmers knew full well what the limitations were in the hardware they were developing for, and likely did things in the design differently than they normally would have, if these 1 frame input delays did not exist. And if using these modified routines provides some sort of advantage while playing, which seems to be the claim, how is this not considered to be cheating at the game?
Pi's are all right. I've been amazed when seeing what those little things can do, like being a better Amiga than a full blown original machine with an expensive modern accelerator, and being able to emulate a Mac under the Amiga emulator, with the Mac emulation being faster than an original Mac
That said, mine is collecting dust. I have too many old PCs, and too little time to go too far down the "Linux rabbit hole." If you already have better hardware just laying around doing nothing, dealing with the Pi just seems like hacking for hacking's sake.
