Using Action Replay cheats in a romhack (Flawless Platinum)

Hi, I am trying to use Action Replay cheats for Flawless Platinum. I have the usrcheat.bat downloaded and put in my _dstwo folder, however the cheats are not coming up when I open the cheat list. According to my research, this is because a romhack has a different game id/checksum as the original version of the game that the codes are for. My question is, how do I change the game id/checksum or how do I edit the usrcheat.bat to use the correct game id/checksum.

Using a SUperCard TWO PLUS btw.
