[hwoarang54]

Hi,can anyone help me ?
i just got a Messiah 3.6 modded PS2 50006, and it got strange problems? The tech modder is my friend but he is bad at english, so he ask me to ask 4 help here,

Here the problem,i tested 2 problems,

All ps1,ps2 dvd movies backup works fine with single tap at reset or twice or just load the tray in for ps2 dvd backup,

But, all his moded 50006 ps2, always hang during the starting movies for the DVD9 backup of Metal Gear Solid 2 Substance,
and Action Replay v2.23 will hangs just before the codelist loading screen,or main menu.

All the disc works fine for my 39006r console,is the modder did something wrong in his modding ? did this happen to anyone?

Please, i beg of you guys can anyone us out, i like to thanks you in advance,

William.
