INES Mapper 036

iNES Mapper 036 is apparently assigned to the board used some games published by TXC / Micro Genius. This is almost identical to oversize GNROM with two changes:

• As a workaround for incomplete documentation­, FCEUX only listens to writes to the range 0x8000 through 0xFFFE, and
• Reads from $4100 should return the value written to the banking register

Strike Wolf writes to unknown registers at $4100-$4103, $4200, and $FFFF.

It's not known what these other registers are supposed to do. Perhaps they're registers internal to the Famiclones made by TXC.
