Converting Excitebike NROM to MMC3
This rom just needs a simple mapper change within the header. This game only uses $C000-$FFFF, there is no $8000-$BFFF. Don't need to setup anything.
UPDATE 12/2/13
Does not display correctly on PowerPak.
Need to increase PRG-ROM by 1, so that it can have $8000-$BFFF to contain the MMC3 setup registers, this has to be installed.
