i have managed to load some games onto my card and they are working fine but now whenever i load a new game it says 'the save data could not be accessed. pls turn power of and reinsert DS card'. i am doing the same as i was with the first games any advice would be great.
It's possible that your memory card is full and that the DS doesn't have enough space to make a new save file.
What cart are you using? Some more recent games give that error with some flashcarts. I dont have a handy link to fixing it, but I know it involves patching the rom.
If you're talking about DLDI patching then here's a link I googled. Not sure if it's relevant or not though.
DLDI patching is for homebrew. I'm talking about the arm7 patch. Theres a program called DSLazy that can do the patching.
If you are using the original R4 you can use anther kernel and it should fix the problem, it is highly likely compatible issue with the kernel you are using. try using Ysmenu here's a guide i found http://www.r4ds-forums.com/viewtopic.php?f=16&t=1957
