I am the author of the latest port to the GP2X. Your post is unintelligible and doesn't make any effort to help me help you. Noone has ever reported a problem saving and I've never experienced it myself. I played through the whole game, too.
First, are you playing my port of the game or an older one by someone else? You can see a link to my version in my signature.
Second, if you are playing my port, have you suddenly encountered this problem after many weeks of playing or did you only just start playing and never were able to save?
Have you tried re-installing the game to another folder or onto another SD card and copying the saved games over?
