Problems with NDS ROMS

Has anyone else been experiencing problems with NDS ROMS over the last couple of days?I've been able to download some that work fine i.e. 1612 Lego Saga but others 1662 Contra 4, 1773 Ultimate Mortal Kombat and 1629 Ben 10 will not load on my DS Lite. All three begin to load on the DS but then present the same error message i.e Data cannot be read. 'Please power off and reinsert the card'. However doing so has no effect at all.At first I believed my flash card was corrupted and reformatted the whole thing but this didn't solve the problem. When I downloaded Lego Saga and this worked fine, I then believed the ROMs in question are faulty.Can anyone help?

Our ROMs are all clean dumps, meaning they have the exact same data as the ones you buy, they're not trimmed or anything. If they don't work then it's the firmware of your flash cart. (reformatting it won't do anything btw, upgrading your firmware might)Thus I'm moving this to technical help as it's not a bug on our end.I'd suggest you read the "common issues" thread of the Technical help section.

Sorry, I'm new at this. I've done as you suggested and everthing is working fine. Thanks for your help.

No problem, at least you could figure out how to upgrade your firmware, many people can't; nor do they have a look in our tutorial section.
