PS1/2 Pal ps1 games on modded ntsc ps2

[mcopo]

So, I have a modded ntsc-u ps2 that is able to play ps2 games from any region and ntsc ps1 games. But when I tried ps1 pal games, the screen got displaced and the game ran at 60hz instead of 50hz. My chip is some kind of matrix infinity clone at v1.89 that came installed on the console. My question is: is there any way to force the system to use the pal screen format when playing those games? Or is there a way to convert them to ntsc?

Btw, when playing pal ps2 games, the screen does "go pal", running at 50hz. So no problem with these.

If no one can help me, is there a ps2 dedicated forum that I can ask this?
I just posted here because I didn't know where I could ask it. Since gbatemp is more focused on handhelds and nintendo consoles, I'm pretty sure I won't find the answer any time soon...

This is definitely weird. I think there is an option to force games to 60hz, try disabling it from your chip.

PS1 mode behaves differently than PS2 mode for some reason. This might be useful, I haven't used it.

Thanks for the help! I'll try these as soon as my tv comes back from techinical assistance.

Oh and disabling my modchip would be useless - I do not own ANY legal game (by legal I mean not pirated/downloaded)
These kind of games used to be pretty expensive around here. They are affordable nowadays though (that is, if you happen to find one for sale).

FINALLY the tv is back. And those suggestions didn't seem to work. When I launch Ps1VModeNeg through ULaunchElf it, it simply goes back to the PS2 browser... Honestly, I'm almost giving up.

You might have to patch the ISO and burn a new copy to get it to work. I had to do that with a game once a long time ago, but don't remember the exact process.

Unless it is a game that only ever came out in PAL, you might be better off just tracking it down as an NTSC version.

Holding triangle + circle while booting brings up matrix settings.

About patching... I already tried it with Earthworm Jim 2, but it didn't work. And at the matrix settings I can only change the color system for ps2 games.

Well, I'm giving up on this. The only pal game I wanted to play so far was EWJ2. I can live without it =)
I was mostly curious about this behavior. I mean, if ps2 games work ok, why not ps1 as well?

Thanks everybody for the awesome help!!

I'd try a ps1 game after it goes back to the browser. Not sure about that, the program's readme is vague.

I did exactly that. Didn't work...
