Mario & Luigi Superstar Saga finally saves now, which it didn't in his last version of the Expansion Tool V1.9d, and I suspect many other games that didn't save before do now. I'm asking around my MSN list to see if I can find someone that can translate Japanese but I've only found one person that knows someone that can so far but dunno when they'd be available for now.
