How Do I Uninstall An App.

Go to the "Manager" application (sometimes in the Settings folder), and you get a list of installed apps. highlight the one you want to remove, and press the "c" key.

The only Apps In There Are The Puzzle Games That Were Pre Install

In whcih the apps you installed were not installed by SIS file. Which apps are you trying to remove?

they were blz. files and sis installer i got some game off the net and installed them. blz. file

Not like normal uninstall. I am sure you know that blz files are cracked games which aint something we are supposed to talk about here!

Indeed those are Warez games and don't have an uninstaller.
Delete them with FExplorer (if you'r able to find all the files and don't delete other necesairy files).

Maybe the best thing is to clear your MMC the best you can using uninstall and then format it...

And just buy MMC gamecards the next time around 😛
