Newer games not working (supercard)

Hi, im currently using supercard "lite", and the newer games i have downloaded dont seem to work, such as Harvest moon Island of Happ, Club penguin, etc. ive used the newer software but im still uncertain of how to upgrade the firmware ,which could be the problem, since the instructions werent too clear.
when i start the games, the screen just goes white and stays like that.
Any help will be appreciated!
Thanks

Download firmware from http://www.linfoxdomain.com/ds/. Extract. Take the files and folders etc. and put them straight onto your card, and overwrite.

yeah, the file should appear as something.bin (example) That will show up in your menu and just hit A on it like you're loading a game. It may ask you to push a button or something after that.. does the rest for you. supercard.cn has all of the updates for it too, although there hasn't been a new one since august.

could Nintendo be putting some sort of lock on the game for it not to be Compatable with most flashcarts or does it work differently

Square Enix have been doing that to their newer games. Nintendo didn't develop this game.
