BMC-SRPG-5IN1 (PCB has no distinguishing label)
Games: Super RPG 5 in 1 CH501
MMC1 clone with banking for multigame menu. Note: This
game does not soft reset properly on real hardware.
The interesting feature of this board is that it has a
serially written 4-bit shift register that selects the
outer game bank (meaning it has two shift registers,
since it also clones the MMC1's). The MSB (bit 3) seems
to indicate menu mode (0) or game mode (1), but it's not
clear if/how this is used. Is it a lock? We currently
don't use the MSB nor allow it to be read back.

In MAME: Supported.
