And it's a bit of a shame the game doesn't support any of good settings. Oddly enough, 800x600 is the highest the menu allows you to go.
Firstly I thought the ePSXe emulator could be an alternative to this, but no. It's flushed out of details and framerate is also quite low.
These are two snapshots I found:
(PC - 800x600)
(PSX version, 1280x960 downsized to 800x600, maxed out ePSXe settings, lots of video card enhancements applied, including AA)
So uhm... no. We rather need some smart ass to come up with a solution :).
