I'm having trouble getting my R4 cheats to work. I press Y, the menu thing comes up. I press X, cheats come up. I use A to select the cheats I want and accept changes. I go back in, cheats are still selected. I enter the game, they don't work. I go back to the cheat menu, and the cheats are still selected. I have tried this for all my R4 games (Which comes to about 8) and not a single cheat works, So i checked the R4 cheat code editor and checked the game IDs of all my games and compared them to my USRCHEAT.dat. They matched up. I checked the cheat codes on several websites against the same ID, they matched up. So I just can't get it working!
So is there anything I can do?

Extra info:
I got my R4 recently, so excuse my stupid mistakes!
I'm running wood firmware.
My microSD is 2GB
The games themselves run fine, all of 'em.

If you need any other info, just ask, please help me!
