I got VRC6 (iNES mapper #24) working for Akumajou Densetsu. Now I'm under the impression that the "other" VRC6 (iNES mapper #26) operates the exact same way... only the addresses are flipped around.
I've been switching $xxx1 and $xxx2 addresses around for mapper #26. I'm trying to get Madara running -- the title screen comes in fine, but when you select a save file is crashes (hits a bad opcode -- PRG swapping problem?)
I have the $8000 reg select the 16k PRG page at $8000, and I have $C000 select the 8k PRG page at $C000. This works for Akumajou Densetsu... but apparently not for Madara (I haven't tried Esper Dream 2 yet).
Are there other PRG swapping registers? Am I right in flipping the xxx1 and xxx2 addresses around? I couldn't find any info that addresses this subject on the site or on the old boards. Any help appreciated ^^
