iNES Mapper 186 is used for Fukutake Shoten's Japanese edutainment game Study Box. This information is currently identical to FCEUX's source.
Write mask: $FE03 $4200 write: [RR.. ....] - select one of four 8 KiB PRG-RAM banks $4201 write: [.... PPPP] - select one of sixteen 16 KiB PRG-ROM banks at $8000 $4202 write: unknown $4203 write: unknown
TCRF claims that there's a printer interface.
Read mask: $FFFF $4200, $4201, $4203 read: returns $00 $4202 read: returns $40 $4204-$43FF read: returns $FF
The readable ports may have something to do with what Санчез describes as an "Audio Tape reader" and "power supply condition". TCRF additionally mentions a touchpad interface.
Memory locations:
$4400-$4FFF: 3 KiB PRG-RAM $6000-$7FFF: 8 KiB PRG-RAM bank (one of four) $8000-$BFFF: 16 KiB switchable PRG-ROM bank $C000-$FFFF: 16 KiB fixed PRG-ROM bank (always bank 0)
Having 35 KiB of PRG-RAM seems unlikely, and probable that it overlaps with some of the bankable 32 KiB of RAM. Санчез doesn't say anything more specific, unfortunately.
