i added a couple of game roms to my psp yesterday and after playing "little master"(for snes) for a while i tried to save state and my psp just went nuts... like going back the menu will take a long a$$ time and it just lags so much so i tried to close the emulator but it still took a while and every time i go to the game menu and browse my programs ex: psp reader, snes emu, gbc emu...etc. it kinda freezes and the mem stick light thingy keeps on blinking meaning its probably having a hard time reading my mem stick.. so i went to photos and i tried opeing a pic. and it worked but for some reason the "last" pic. on my list doesnt work my psp will say unsupported format or something and it couldnt open the pic. so i connected my psp to my computer and tried backing up my save files and guess what?! i cant!!! (ever experienced copying a file from an f'd up cd? like when you try to click or right click on a file it kinda freezes or it takes soo long? thats what its like for my psp and again the mem stick light thing keeps on blinking..then it after a while it sez error copying/moving file cyclic redudancy check something..) and yes i've formatted my mem stick for like a hundred times now and i even restored it to the original settings and stuff but its still like that and for some reason its always the last file that gets messed up... like id put all my games on one folder then copy it to my psp, all of it will transfer except for the last file and the error thingy will come out... pls. i really need help. i have 256 sandisk, could it be my memory stick? i also tried cleaning it and stuff but its still the same or is there some sort of program that i could use to fix this problem?
