M3 DS Real

I started using my M3 DS real again. I downloaded the lastest System software for it and some games in the NDS folder. The MS DS software loads, asks for language selection, etc. I can see the games in the NDS folder in the GUI. I click start for a game, it creates a save file, then both screens go white and nothing loads. It happens each time I try, even after the save file is created. Any ideas of what is going on, my cart worked before?
I use a DS Lite.

 

sorry for the double post, did not think the last one posted

 

Have you tried the sakura firmware? I get random freezes occasionally with touchpod when selecting games.

 

I tried it all, nothing seems to work.

 

How old was the original firmware, if it was very old then the new save files are different to the originals so causing issues.

Format the card with panasonics SD formatter (its free - google will find)

Add the latest System folder

Create a new NDS folder (with Sakura this can be named anything you like)

Add the clean roms and try again
