Espresso is an all-in-one GameCube and Wii backup managing tool. It's made to work with FAT32 only.
This program is powered by (or copy pasted from) GameCube Backup Manager by AxiomDrak. Please go support him instead, as he was the guy that basically had the foundation, while I just took it and ran off with it.
There really isn't much here right now, nor is there anything original (for now...).
