There is a patch that can allow the game to save on some loaders that use a flash chip in the kit. The new NAND saving method keeps the game from saving. Just be paitent and wait for a patch. I want to play this game as much as you dude. In the meantime, why doesn't someone make a translation for this game? That would be nice.
I read somewhere that this game is plained to be fixed in the next AKAIO version (1.5)
