I am pretty confuzzled myself. I used pocketdos and was unable to get hugos house of horrors to run, was giving me some video player. Managed to get DUNE to work fine, but was brutally slow on my 2215. I tried ACTION SUPERCROSS and couldn't get past the title screen, might be that it takes more than 5 minuits to get past it or something, but I think it locked up which sux, i love that game
[EDIT]
N/M, across works fine, if you enjoy playing games at 1 frame per minuit
