This is not easy because there are some things that one or other system can't run, for example games with mp3 music files in background, in 68k the mpga.library and on an Amiga classic these games run slow, or using much graphics of big size, this isn't problem with 68k under emulation but not with a real Amiga or running WinUAE in old PCs, for example with CPUs of 600MHZ as is my case, with my old K7.
