Hello.
I tried your new version 1.1 and, at first, it was not working too.
But then I decided to disconnect the Xplorer cart I had attached and this time the game played correctly.
For curiosity sake, I went back and tried again v1.0 which failed the first time and to my surprise it also worked!
It seems to get the game working the cart has to be actually removed, disabling it with the on-off switch won't do.
The only downside is that I won't be able to input codes for disabling the dithering effects on some of the graphics but I think I can patch directly the slus file to achieve the same results.
I still play on real psx console linked to crt tv or monitor but I have to admit that sometimes 3D games with scanlines don't look very nice, with the rare exceptions when interlace mode is used.
