@kogami, that would be an interesting addition. The BS-X memory packs generally use a Sharp flash chip with similar instructions to the SF Memory carts. I have a couple of the BS-X carts that I could test. Maybe I could look into it if I ever find some free time. The other cart type that still needs support is the Sufami Turbo carts. I have a bunch of the Sufami Turbo carts but I never got around to examining them.
