Notes:
--------------------------
This mapper is a modified MMC3 (or is based on MMC3?).
In addition to any CHR-ROM present, there is also an additional 2k of CHR-RAM which is selectable. CHR pages
$08 and $09 select CHR-RAM, other pages select CHR-ROM
Apart from that, this mapper behaves exactly like your typical MMC3. See mapper 004 for details.
TODO: implement CHR-RAM behavior
