iNES Mapper 207 represents the board used for Fudou Myouou Den.
It modifies Taito's X1-005 (80) in the exact same way that TLSROM (118) differs from MMC3 (4), by which we mean the X1-005's CHR A17 output is connected to CIRAM A10. Thus, it achieves 1scA/1scB/H controllable mirroring instead of H/V.
