Hi Acris, this is what i have search. Thank you very much. For me, it works with: mount -o remount,rw / Now i can resize my game images :-))))   For the next People who has this question: try: mount -o remount,rw / or try: mount -0 remount, rw /boot when you go for a restart, the system will be again "read-only"   Greetings abunille

I've saved most of the older releases and always backup my sdcard and roms. I just copied them back to the new install although the games played without them?
