For all of you R4 user's that are running your game off the arm7/arm9 patch here is a solution for you if you want to use wifi. Step 1. Install YSmenu onto your R4 flashcart. Guide on how to install it found here: http://gbatemp.net/index.php?showtopic=976...t=0&start=0 Step 2. Put a clean GTA:CW rom (as in unpatched, trimmed, or modified in anyway) onto your R4. (You can still use your previous save) Step 3. Update your urscheat.dat file with the Bypass save error Action Replay Cheat. (If you are to lazy to manually put in the code your self download the Massive Cheat Compilation which is constantly updated. Thread found here: http://gbatemp.net/index.php?showtopic=84991 ) Step 4. Start up your DS/DS Lite. Step 5. Go to your GTA:CW game. Step 6. Select the Bypass Save Error cheat (or whatever it may have been named) Step 7. Start the game. Wifi now works. - EpicPie Edit: If this could be pinned I would greatly appreciate it, every forum I go to for DS related stuff people constantly ask how to get wifi to work on GTA:CW without the game freezing on them. Here is the solution.
