CWCheat codes don't work on DBZ: Tenkaichi Tag Team only

[Yeseah]

Hi everyone, I have a problem with PPSSPP on my Android device where CWCheat codes for Dragon Ball Z: Tenkaichi Tag Team (ULUS-10537) don't work at all, but codes for other PSP games work. (I tested Persona 3 Portable and Mortal Kombat: Unchained on the same Android device and the codes for those games worked.) I made sure the codes I'm using are for the right version of the game, and interestingly the codes do work when I try it on my PC (same ISO and everything), so I'm not sure what the problem is when I try to use it on my Android device. If anyone knows what I can do about it I would greatly appreciate it, thanks!
