Advance wars save game, anyone test it ?

[sixbras]

Thanks a lot for your help. This week-end i patch my Roms and it work just fine now.

By the way it's necessary to perform a clean exit (hotkey + B) to return to the main retropie menu to "validate" the save. If you don't, and just power off , with a long press on power button, save is not available.
Same issue with zelda "link to the past" for exemple.

Is it a standard behaviour, or do i miss something ?
