iNES Mapper 036 is apparently assigned to the board used some games published by TXC / Micro Genius. This is almost identical to oversize GNROM except that—as a workaround for incomplete documentation­—emulators only listen to writes to the range 0x8400 through 0xFFFE.

Strike Wolf, at least, writes to registers at $4100-$4103, $4200, and $FFFF. It also tries to read from $4100.

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