DSTT freeze

well, yesterday i installed ysmenu and dsision2 on my dstt.
it starts freezing when i load a game after i used dsision to load games(not sure if it did that before I started up dsision cuz i only loaded dsision asap to see if i configured the ysmenu correctly).
i choose a game and the loading square immediately freezes on the dstt OS, but it loads fine on ysmenu/dsision2.is this a sign that i need to reformat?

Usually yes. Make sure to backup all your files too.

thanks, it worked.also, if I get a 4GB mSD, will that speed it up a bit?
the second largest thing on my dstt is the dsision files, and it's pretty much one large file scattered into many smaller ones+the caching of loading roms...

Depends on the brand, how long you've had your old MicroSD etc.
