why do i have to write GBA roms several time on my M3 mini sd before getting a rom to working. ( the NDS roms always work at first time) For example, if i write 15 roms. only 10 will work. i have to erase the 5 not working and rewrite these roms. Then maybe one or 2 of them will not working again. so i have to rewrite the 2 others and then all is working. I ALWAYS USE DEFAULT SETTING WITH GAME MANAGER thank you for your answers. What do you think ?
