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
