Here are Disch's original notes: ======================== = Mapper 182 = ======================== Example Games: -------------------------- Pocahontas Super Donkey Kong Registers: --------------------------- This mapper is an MMC3 with its registers all scrambled to hell. Rather than a typical register outline, this section will "translate" mapper 182 registers to their coresponding "normal" MMC3 counterpart. For MMC3 details, see mapper 004. Range, Mask: $8000-FFFF, $E001 Mapper 182 MMC3 -------------------- $8000 - $8001 $A000 $A000 $8000 (addresses further scrambled, see below) $A001 - $C000 $8001 $C001 $C000+$C001 * $E000 $E000 $E001 $E001 A write to $C001 would be like a write to both $C000 and $C001 on a normal MMC3 (sets reload value, and clears the IRQ counter). The Address/Data port registers are further scrambled: Mapper 182 MMC3 -------------------- R:0 R:0 R:1 R:3 R:2 R:1 R:3 R:5 R:4 R:6 R:5 R:7 R:6 R:2 R:7 R:4 Other than this scrambling mess, the mapper operates exactly like a normal MMC3.
