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.

Registers:
---------------------------
$7EF0: [MCCC CCCC]
M = Mirroring 0
C = CHR Reg 0
$7EF1: [MCCC CCCC]
M = Mirroring 1
C = CHR Reg 1
$7EF2-7EF5: CHR Regs 2-5
$7EF6-7EF7: was old mirroring control register, now ignored
$7EF8-7EFF: see iNES Mapper 080

Mirroring:
---------------------------
[ $7EF0 ][ $7EF0 ]
[ $7EF1 ][ $7EF1 ]
Mirroring bit of appropriate reg selects NTA or NTB
