NTR-CFW provide you with cheats of several titles. Just search the web, or check speedfly.cn with translator.
Or else, you can try dumping the main memory of the game with it, and search for some your own.
Or, you know there is Spider AR, could do a little job.
I used NTR for memory edit, and hex-editor or dedicated save editor and cyber codes for save edit.
The one from gateway has time to come. So.. "SOON (TM)" for that.

EDIT: Forgot to mention, i don't use those edited data to play online. My network sucks.

 

Gateway Cheat support is still coming soon. I emailed them asking for an ETA, they actually said any day now (as of today) and are in the final step of testing it
