Ok, first off i am a newbie so please be patient with me... I have read around, have not directly seen the answer to this so heres my question... I own a slim line ps2 model number scph-70012. I have never had a problem backing up my games (thanks ALOT to the people that has discussed numerous ways to do this!) But i have been having issues about my swap magic coder not booting up every time. I can play a back up games with no problem when i have not use my ps2 for a while. but when i play one that i like then want to play anouther (doing the swap out all over again for a new back up game) i get the "no data on disk" screen were you would see your memory card and such... Ive tried the unplugging the system, cleaning the lens with a dvd / cd disk cleaner...CLEANED the boot disk itself and im still getting this issue. I can play my normal games by ps2 with no problem after i play a back up, im just not sure what could be wrong. I have 2 copys of this swap magic coder and if the one don't work the other does when i want to play the 2nd game...EH? Any ideas???? Thanks for your time and help guys!
