Wow. Its been a long time since I have used my r4. First you do know that those cards are basically dead, well they are dead. Anyways, you can still get the games to work. Now I havent touched my r4 is maybe 6 months and I am alittle rusty on this but do you know you can patch the games to get them to work? I dont remember off the top of my head what the messege says but for any game that gives that messege when you try and load it, you use dslazy to patch the arm7 file inside the game. Youll use dslazy to open the game. Then you want to unpack the game and remove the arm 7 file and use your patched arm7 file in its place. Then repack the game and your good to go. Now I dont know if that still works on the new new games because I basically dont use my ds anymore. Also if you need detailed instructions, I wont be able to help you because I am rusty with this stuff.
