Doesnt work on Nestopia or PUNES64.

REVISITED 11/16/13

OHHH I forgot! Need to enable WRAM, cause $7F00 has a ton of JMP adresses within there. So I'll just adjust my reset vector so that $A001 has 80 in it.

$1FF90 = 78 D8 A900 8D0020 A901 8D00A0 A980 8D01A0 A900 8D0080 8D0180 8D00C0 8D01C0 8D00E0 A205 8E0080 BDB3FF 8D0180 CA 10F4 4C00C0 00 02 04 05 06 07

Also, need to correct mirroring routine at $1EB17, this routine is JSR'd to alot. = A901 8D00A0 60

DONE! GREAT! That did it! All emulators & PowerPak run Kid Icarus!
