PS1/2 Issue with OneChip

[Woxinum]

Hello everyone,

I bought a PAL PsOne (SCPH-102) and soldered OneChip (8 wires) on it. All my PAL original games still works great (fortunately) but i tried an original Suikoden 2 NTSC-US and this screen appears:



I also tried to quickly burn (IMGBURN, x16) Einhander NTSC-US and i got the same screen. What does it means?

If there was no chip on my PsOne does this screen will appears aswell if the region is not compatible ?

Thank you for experience.
