I've got custom firmware 3.80 m33-5 and i've got a fifa 09 cso, which i can load up and it looks like its going to work but then it suddenly says the game could not be started, what can i do? I've changed my usb iso mode to m33 driver and my burnout dominator game works fine so why doesn't fifa? Also how can i update my firmware to a more up to date custom firmware?
Make sure under your VSH menu that your USB device is mem stick and your umd iso mode is sony np9660.
