Hi there, so I'm new to this but so far have managed to get my R4 card to play all of the downloaded games I have with exception to GTA Chinatown wars. I've seen threads talking about a fix or patch or something but no idea what this means or how to sort the problem out. Whenever I try to open the game i get the following message "the save data coud not be accessed. Please turn the power off and reinsert the DS card ." Any help with sorting this problem out would be appreciated I can now get the game to open by doing the patch arm7 thing but it wont start. When you get to the 'do you want enable autosave' whether you select yes or no the screen goes blank??? Please help??
