GRAND THEFT AUTO : CHINATOWN WARS need action replay help on R4

I downloaded the patched version of GTA:CTW from a romulation forum not long ago. However when I try to use action replay codes that I put in there, it is not recognised, theres no Cheat(Y) tab underneath the game title. THANKS IN ADVANCE ;D

quote from cjdogger, download cheat.dat and put it in your _system folder

You will need to find the updated Game ID of the patched ROM using R4CCE and then modify that into your usrcheat.dat database file.

If you're running a R4, there's also a good chance that you can't use the cheats because it's too far down on your cheat list.

Removing entries, or simply switching to YSMenu can fix that.

THANKS
