Sometimes when i'm playing it just stucks. For example in mario kart it usually stucks while it changes the map. Can you say it a map? : D and in donkey kong jungle climbers it stucks after dying or after finishing level, anyway whenever it loads probably. So i'll get blackscreen and maybe some music on the background. I'm not sure if all the games stucks, but atleast those two, mario kart and donkey kong jungle climbers. Haven't played so much games yet, because it's sucks to play 20 games at the same time. Anyway, is this a common problem, easily fixable or am i just unlucky? ps. i've used r4ds romtrimmer 2.0, dunno if it's good or not. And microsd is formatted to fat32, if that matters anything. And i've 1.11 fw on r4. It's not a big deal if it's stucking sometimes, but it's annoying in some games where you can't save whenever you want. Like after playing 15-20 minutes one level on dk jungle climbers and getting every coin and stuff... it just stucks just before end..
