Itouchds card will not run nds games

downloading the new nds games from Romulation will not run on old M3 card but having bought Itouchds card will not run games at all - only shows white screen. Kids not very happy. What do I need to do to get the games to run?

have you installed the itouch firmware on the card?

Installed boot.end and itouch folder as per instructions in itouch user manual. Runs the itouch language no problem but not downloaded games.

Did you extract them? Just making sure. And what games aren't working?

Extracted as per instructions - but seem to have resolved the problem. Took original firmware from itouchds.com site which is version 1.7. Downloaded version 1.9 from different site and now it is working.
