Need some help. Whats wrong?

Hey im having trouble playing some games, I have an nintndo DS lite with the R4, SanDisk 512mb micro SD and when i try to play some games that i recently just downloaded this is what it says " could not read the data. Turn off the power and reinsert the Game Card " and in some other games it starts to work but then it stops and says " Cannot access save data. Turn off the power and reinsert the DC card " Whats wrong? How come its like this? Thanks for all the help.

 

make sure you have the latest version of it. thats all i can think of.

 

what is the latest version?

 

Not sure about the G4, but on the M3 some games require an ARM 7 fix.

 

i believe it is version 1.11, r4ds.com. not sure though.

 

@Svstang: That's only needed on Worms 2 and the Slot-2 carts.

The Firmware that Dragnandy is talking about is Here.

 

thanks for the update, that is why I said I am not sure. I have a m3 lite and a lot of games need the fix regardless of my firmware.

 

so to fix this problem all i need to do is udpate my R4 right?

 

not 100% sure what the problem is though, but getting the update might fix it, it wont hurt updating it thats for sure.

 

Yea, it just needs the firmware update and it will work just fine. I had the same problem and finally found a thread somehwere that told me that, but i dont have the website for the firmware update. But its only newer games that its doing this with.

 

Cant edit my post, but the Link that nintenut is where i got mine, that should work, readme was very easy to follow.
