Take a look in the Common Issues thread for Save issues.

If you are having problems with saving on Acekard2. Hold down X while loading rom (hold down x then press A while x is still pressed)the loading turns red
Now you can save! You will have to load the rom like this every time though.

Only possible if you're using AKAIO I believe. Anyway, the original poster hasn't come back, so I'll lock this.
