This is probably either a duplicate of one of mapper 33 (Taito's TC0190)'s variants, or yet another variant.
FCEUX implements mapper 250 as an MMC3 variant where instead of using the LSB of the address to determine which register to write to, it instead uses the 0x400s bit. (i.e. the registers are at 0x8000,0x8400,0xA000,0xA400, &c and their mirrors)
