SEGA Grand Pianist

SD Card

SD card slot is on its own separate PCB connected via a 8-pin JST PH (?) jumper cable.

Tested with 2GB SD card formatted with FAT16. Cards smaller than 2GB might also work but are untested (since the smallest cards I got are 2GB).

(Official spec stated that it supports 128MB-2GB SD cards formatted with FAT16.)
