I asked becasue the file extension is normally .fds unless you get a hacked/ patched version - I know there was a patch for the pocketnes emulator on the GBA that you had to apply to get it working properly
IIRC I had a .nes rom of the lost levels, so it should be out there somewhere.
If it's not, then I've got question 2 here for you
:
Did the patch fix the rom or the emu? If it fixes the rom, see if the patched rom works for nesds.
If it fixes the emu, then I can't think of another way to get it working.
