games not working?

Hi all.

Downloaded a few more games for my son last night and this morning, been using Romulation for a long while now with no problems.
Now the problem is that I extract the zip file and then transfer the NDS file to a 4gb micro card as per normal, running TTDS card BTW and all of the files when opening them with the DSi come up with file failure code 7??

I have had this a few times in the past but it just seems strange that I downloaded 6 games some of which are duplicated so done them all and they all are faulty.
Is it me or just the download ?
Many thanks.

Think I have just solved the problem,
I have just updated the TTDS program, TBH I didnt realise that they were updated :

Hi bro, the last post (the post merge part) has started the answer, so update your firmware
