This mapper appears to be designed for making a multicart of multiple [[Color Dreams]] games.
This mapper represents the [[wikia:c:bootleggames:Rumble_Station|Rumble Station]], a combined NES-on-a-Chip and multicart of licensed [[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 outer mapper, selecting 64K CHR ROM banks (bits 7-4) and 64K PRG ROM banks (bits 3-0), is at $6000-$7FFF, and the inner mapper is a size-reduced subset of 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.
Together, this supports up to 1 MB PRG ROM and 1 MB CHR ROM.

This mapper represents the Rumble Station, a combined NES-on-a-Chip and multicart of licensed Color Dreams games. The outer mapper, selecting 64K CHR ROM banks (bits 7-4) and 64K PRG ROM banks (bits 3-0), is at $6000-$7FFF, and the inner mapper is a size-reduced subset of Color Dreams (#11). Together, this supports up to 1 MB PRG ROM and 1 MB CHR ROM.

 Here are Disch's original notes:

 ========================
 
 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.

Nestopia and FCEUX reset both registers, not just the outer bank.
