Fantastic cart. Working beautifully on my supercic modded pal snes.
Seller was very helpful in reminding me of long forgotten information regarding the snes. Can't recommend this item highly enough, same goes for the seller.

It has all the functionality of an official SD2SNES cartridge. What impressed me the most was the attention to detail; not only does it support compatibility with expansion chip games, but the MSU-1 and USB functionality also work perfectly. Additionally, the seller was kind enough to show in a video how to insert the CR2032 battery into the cartridge, as well as providing the relevant firmware files to boot the cartridge. Quite good value.
