GTA Chinatown Wars save crash

I'm playing gta chinatown wars on an r4i and it occasionally crashes while saving, when i restart it says the save file is corrupt, which deletes the autosave and my manual backup, anyone got any ideas?

are you playing patche gta china wars works great i have fake r4i sdhc red wich runs great in 106b firmware try that firmware if you need save im kind of far on game i can upload a save 106b and patched fixed rom works good

Make sure you have the latest firmware. http://www.linfoxdomain.com/ds/

i am running on R4i ultra with 1.54 which is the newest available on there site i has only happend twice and always on autosave, but i got to 53% so i dont want to play through again to loose it aigin

it has been happening to me twice, but i think its just getting corrupt because of improper saves. if autosave is off, it works without a problem.
