iNES Mapper 011 refers to the Color Dreams board, used in several unlicensed games.
Here are Disch's original notes: ======================== = Mapper 011 = ======================== Example Games: -------------------------- Crystal Mines Metal Fighter Notes: -------------------------- This mapper suffers from bus conflicts! Registers **BUS CONFLICTS**: -------------------------- $8000-FFFF: [CCCC LLPP] P = Select 32k PRG page @ $8000-FFFF L = Lockout defeat usage C = Select 8k CHR page @ $0000-1FFF Lockout defeat: -------------------------- I have no idea how this works. Kevtris page makes mention of it. From an emulation standpoint, it's not all that important.
FCEUX's implementation:
$8000-FFFF: [CCCC PPPP]
Nestopia's implementation:
$8000-FFFF: [PPPP PPPP] [CCCC ....] note that top 4 bits mean both PRG and CHR
