/vr/ - Retro Games

Hey /vr/os.
I have a thread in the catalog, but have been told a few times to ask you guys.
I have a modchipped ps2 (Matrix 1.93) I got from a lot, not knowing it was chipped.
I decide to try one of my import games from japan (guilty gear XX slash).
But when I put it in, I get the 'insert a playstation format disc' screen.
I've tried playing japanese region DVDs and they work perfectly fine, but for some reason ntsc-j games are not working.
I've tried both a ps2 and ps1 ntsc-j game and neither worked.
It's a PAL ps2 if that helps.
Thanks.

I have a modchipped ps2 with matrix infinity 1.93.
Decided to buy a japanese game online (guilty gear xx slash) to play on the mod chipped ps2.
Got the game today, put it in the ps2, and when I try to start the game I get the 'Insert a playstation format disc' screen.
Is there some setting I have to change to make it region free?
Was expecting it to just work.

I just recently bought a ps2 lot off someone and to my surprise it turns out it is modchipped with Matrix Infinity 1.93.
My question is, how do I play import games on it?
I have a japanese copy of Final Fantasy 9 on PS1, but whenever I try play it, it comes up with the 'insert a playstation format disc' screen.
