Problems loading a game.

I just got the JNES Emulator...way better then most on the count of easy save state files. (what I mean is it's easier to save my current positions in games with this NES Emu then most NES Emu's I've tested.) When I try to load Fantastic Adventures of Dizzy, it says Mapper #71 not supported.

Do I need to download an extra pallete or this mapper #71? Oh and it loaded just fine on other NES emu's...just not with this one. All the other games load just fine...

it's 0.5.3 I tried the new version and the game barely runs at all...it lags heavily...it's only one game...I doubt it really matters anyway...most of the games I've tried thus far work just fine. (most of the ones I've yet to test, mainly cause I'm still playing the others first. )

okay...does your comp have to be at a certain speed for the JNES 6.0 to run smoothly?
