hi all i just bought swap magic 3.8 corder. i installed on my ps2(slim lately model), parts 1. 2. 3 and boot with swap magic disk work well so far but play the games random freeze happening. so i think that the backup dvd is problem. so i change the dvd. but also random freeze happening. what is the matter? my dvd stuff is 1st class(sony) ps : when i paly the backups do i have to open the case(flip-top)?
