Demon Stone isn't the greatest game ever made, but that's alright - it's still good PS2-era button mashing fun. The port and upgrade to modern PC is, however, not very good and will flat-out not run using most resolution settings. The graphics can be upgraded a bit with DLSS image scaling and RTX dynamic vibrance.
This game will forever have a special place in my heart as one of the most "Star Wars" things to have ever been made. However, the game requires some manual tinkering to get basic 3D acceleration to work, and I cannot get the background music to work at all, in spite of an impressive effort by the community. Your mileage may vary depending on your operating system.
