Couple of weeks before, I posted a blog saying something is wrong about my game (GTA chinatown wars) that "I was trying to play GTA Chinatown wars on my R4 DS, but it didn't work. It says "The save data could not be accessed. Please turn the power off and reinsert the DS Card." I reinserted the DS card but it couldn't work. I'm not sure if they are asking me to change the version of my R4. (I Have V.1.18) I am really not sure. If you can help me, I can really appreciate it." and I used it well but some other games wont work and if i want to use cheats, I cant use it for GTA chinatown wars. Please answer Do you think v5.2 would work on Grand Theft Auto China Town Wars?
I have no clue what you mean by v5.2. On the original R4, just get the Wood R4 firmware and run the game clean. No patches needed or anything.

use wood r4 1.08 everyone is using it now for the r4ds and its really really good. you can download it from this site.
