Hacking need helpppp

[Blackcat_XIII]

Hi.
I recently bought a NDSL and DSTT card with 1 GB mini card. And.... i downloaded some games and put them into the card.
Then when i turned on my ds and select the game, it started downloading and creating save files.
At about 70% a black warning box appeared saying that Rom download faillure...
error code 214xxxxxxxxx and...at the end it said reset system.

How do I fix this problem ???? plzzzz help me..
and thank you.

The ROM you were loading must have been a failed dump. Try another game that you know will work.

Hope that helps.

I can play some of the game, but not all of the games work..!!!!!
..it said... Downloading Rom failed.
please reset the system...

I can only think of two things why this is happening for some games and not for others.

1.) You have some Roms that are failed dumps. Try dumping/downloading them again from another source.

2.) Your SD Card is having compatibility issues with reading/writing. Try another quality SD Card.

Possibly using badly trimmed ROMs?

Formatting your Micro SD may do some good

Thanks guys.
Do you mean format manually ? so I delete everything in the card ?
What do you mean by badly trimmed roms?
