This mapper appears to be designed for making a multicart of multiple Color Dreams games. The outer mapper, selecting 128K CHR ROM banks (bits 7-4) and 128K PRG ROM banks (bits 3-0), is at $6000-$7FFF, and the inner mapper is otherwise identical to Color Dreams (#11). The number of bits in the outer mapper's register is not confirmed, but from only the description, it supports up to 2 MB PRG ROM and 2 MB CHR ROM.
Here are Disch's original notes: ======================== = Mapper 046 = ======================== Example Game: -------------------------- Rumblestation 15-in-1 Bus Conflicts?: --------------------------- No idea whether or not this mapper suffers from bus conflicts. Use caution! Registers: --------------------------- Regs at $6000-7FFF means no PRG-RAM. $6000-7FFF: [CCCC PPPP] High CHR, PRG bits $8000-FFFF: [.CCC ...P] Low CHR, PRG bits 'C' selects 8k CHR @ $0000 'P' select 32k PRG @ $8000 Powerup: --------------------------- $6000 set to 0 on powerup.
