Takka releases CWCHEAT for 6.20 TN-A. Now you can cheat each and every ISO you’ve loaded on that memory stick of yours. You can ctivate CWCHEAT for 6.20 TN-A in game.txt, which should be located in your seplugins directory. If you’re unsure, read the instructions for Game Categories Light. The same idea but you’re using game.txt instead of vsh.txt. Once you’ve done that, start your game and hold select until the CWCHEAT menu appears.
Update: With the cheat database added, under the seplugins directory, where game.txt, vsh.txt, and the prx files reside, create a new directory called “cwcheat.” Copy cheat.db there so you end up with this: seplugins/cwcheat/cheat.db. Now try.
