some people have problems with this (kingston 4gb class 4 taiwan c04g) or other microsd cards. i use acekard 2 hwid 41 with above microsd card and akaio 1.8. i can't get to work soft reset (black screens after key combination) and super scribblenauts (looping intro, no matter which rom i use). i tried different format combinations: - panasonic formatter - full format + gparted partition fix - windows fat - windows fat32 results are always the same. of course it was easy working by just putting rom and akaio 1.8 (the same settings) on kingston 2gb japan... what can i try except this? are these microsd/akaio's/both issues and will these be fixed in another akaio or do i need to buy other card? which brands 4gb or above are very fast and working perfectly with akaio?
