Ok so i've had my R4 ds for about a year now. It works ok like the games dont lag or anything but sometimes when im playing a game, it just stops or it becomes frozen. then i turn it off and i have to redo everything again. its not in a certain part of game, it just happens. Is there a way to fix this? I couldnt find a way to fix this. ive been using 1.18 firmware, is there a new one?
