Don't bother that emulator has damn near perfect compatability. If you are having trouble getting a rom to work go to the options and try changing the country to somthing else. Your rom also might be the problem so try a diffrent version of the same game. I think they only games that really do not work are streetfighter and ghouls and ghosts and a small hand full of others that use supergraphics which is not supported.
thanx for the link =)
1941 is not tested on it. and about options the only one I didn't touch is frameskip (and clock rate of course, but I wouldn't dare this one ...
of course I tried all the dumps. too bad, 1943 is too ugly compare to this one =)
the link provided doesn't show the whole list. You can find it via gp32emu. Anyway, it has had a few pbs lately and I have to post updates for galaga as first games (I know, it's been month I had to correct them).
There were 5 Super Grafx Gamers released that I know of, but remeber it does play all PC Engine games
