I can't get Sm3.3 to do a refresh neither. I am using the slim tool on my pstwo v12. When I enable the internal switch it says "insert bigger toc disc" then I do and disable the internal switch then it just go back to the startup screen and says "not a valid ps2 disc". If I do the exact same process with my swap magic 3.0 cd disc (dvd disc is damaged) and do a toc refresh it works perfect. I need this for the game ris of kasai to work.
