This mapper is used for instance by Urusei Yatsura - Lum no Wedding Bell,the Famicom version of Jaleco's Momoko 120%.
Supported in r3420 BizHawk, r2696 FCEUX (probably has been supported for eons), and reportedly MESS.
Registers:
---------------------------
$6000-7FFF: [CCCC CCCC]
C = Selects 8k CHR @ $0000
It's unlikely that more than 2 bits of C exist.
This is approximately the same as mapper 87 but with the bits in order, or the same as CNROM without bus conflicts.
