ok, that happened to me...i fixed it...what u have to do is delete everything...EVERYTHING...i had to delete all other files that weren't needed for cf...I had to delete all the apps except the necessary ones...I know it should have enough ram to run it without deleting everything, but it doesn't. You have to delete EVERYTHING...
chrono trigger...and ff7...the best
also if that doesn't work, clear the RAM after deleting everything...ALSO I FOUND THIS VERY IMPORTANT AND HELPFUL:
Do NOT save until after crono leaves the town...the map takes up too much memory and making a save file leaves too little ram to run the program. Wait to save until you get to the part with terra. Then everything should go smoothly.
