Installed Matrix Infinity on my old model of the PS2, the big one. It's a PAL version. Have played imported NTSC titles (Ps2 games), and of course PAL games, both PS1 and PS2.

Recently, I bought some PS1 games, of NTSC format. They were: Suikoden, Suikoden 2 and Symphony of the night. None of them work!

What happens is:
I try to launch a game, and a message comes up: "Please insert a Playstation or Playstation 2 format disc". The background is pretty red-ish in the browser at this point.

So. What the hell is wrong? I'm desperat here, guys! Can someone please tell me whats wrong? I have the latest Firmware (1.88), and I have tried to change videomode from PAL, Color to NTSC. Nothing changes.
