 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

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
