Info on mapper used for UMK3 hack

Post by db-electronics » Mon Apr 24, 2017 2:44 pm

I've been looking for info on this online, from what I've been able to find it didn't use the SSF2 mapper but I can't seem to find specific info on how it mapped its data in the cartridge space. Anyone have any info on this?
What does db stand for? Well that's an excellent question...

Flat mapping with !DTACK generation in 9th and 10th MByte. It won't work with 32X present, and causes bus fights when MCD is present.
