Yes i would use miniSD but i cant find it where to buy and i cant transfer stuff from laptop to it (dont have money to spend anymore on the card readers)
So micro to mini adapter is my only choice.
Thanks for the help,i will read them now and try that tomorrow when i get it AND inform you.
EDIT: Also what will go wrong if i add 1.85,instead of adding 1.7?
Because i will bring only micro sd with one game inside,and the GBA SP.
The dude who is selling it to me,is gonna bring adapter so we will try it there and its on the street. I just need to make sure that the card is working with my micro sd.
So i dunno if i should add 1.85 to my micro and update it tommorow when i try it out.
Sorry,noob to the GBA and flashing...
