When i go to drag or copy and paste in the material it says that the filename must be under 8 letters but when i change the file name it just changes back automatically to the way it was
do you mean that you have a gamefile like : joe bloggs and his amazing platform game.prg - and it wont work ? you need to first rename using Win Explorer and not the GP32 manager
emus go into gpmm - and have a read of the .txt as you may need a subfolder for that particular emu
