Problem getting ROMs to run and replacing ROMs

Right, so I only started using your site yesterday... but Im having a few problems getting a few ds roms to run.- Professor Layton and the Curious Village - Im sorry if its been said (Probably has but i couldnt find it anywhere) - Just loads a blank white screen and doesnt go any further
- Yugioh GX Spirit Walker freezes when you type your name in...Diabolical box worked fine though, thanks a lot!Erm so yeah I tried to get rid of the ones that didnt work and put new games from my computer on but now I cant seem to get rid of the silly things. Deleted them off my card, put on Kingdom Hearts ... loaded up and woah, the original games that dont work are still on the card. Tried deleting them again... still there. And my new game hasnt turned up either.Please help me :(Thanks!

hi
certain games have a set cartridge backup media setting
meaning for a game like driving theory you would need to set the NDS CBM to 0.5KBytesand for a game like super mario 64 you would need to set it to Flash 256 or 512try setting the CBM differantly and resetting the game

Im sorry...I dont know much about roms. How exactly do I do that? Thanks :)

You don't unless you're using an emulator, idpaul probably didn't read your post thoroughly enough.That said, the first step to solving problems is reading this thread: https://www.romulation.org/forum/index.php?topic=1462.0

Ok cool. Im using an R4.I've found the solution to the game freezing... being format your card, but I cant see anything about games not being deleted? Sorry if its there, but im still stuck with it :( Thanks!

Are you sure you are deleting the games and not just the save files? One will be .NDS and the other will be .SAVIf you only delete the SAV file, then the game will still be there.

Nope.. I put all my games in folders so I just deleted the folder.Um I just tried to format my memory card and the stupid thing wont even do that. I think there must be something wrong with it. Am i doing the right settings in FAT32, 4096 bytes, etc? It looks like its doing it then promptly tells me that it failed to format. So Im stuck with all games that wont delete or format at all yet they all play fine (except for the broken ones) even after I've 'deleted' them.Hmmmmm.

Some MicroSD cards have a lock function where it goes into read-only mode. Check to see if there's a tiny switch on it.

Cant see one... :(Ok so i went out and bought a new card today. Formatted it. Put all my games back on. Yet Im having problems with all the games I've downloaded from here :( The other ones are fine...Kingdom Hearts 358 days freezes after you start a new game
Professor Layton and the Curious village still doesnt load up...
and Yugioh GX still freezes as i try to type in my name.So formatting hasnt really solved... does anyone have any other ideas? :( Or has anyone got these games themselves? Thankssss.

Great, thanks a lot, fixed the Kingdom Hearts issue. I checked the other thread and all I can see it says is format card and I've tried that as much to an extent as buying a new card. Sorry to be a pain. Is there anything else I can do? Or should I abandon it. Thanks

You could try using a trick called arm7 patching, there might be a tutorial on it. That's generally what R4 people do when games doesn't work on their flash carts.
