I've no idea if the work that Chris Senn and Ofer Alon had done on the PC could even be ported to the Saturn, but their work - achieved in just a few weeks, no less - is far more ambitious than anything Sega Technical Institute or Point Of View managed to produce in months of trying/failing. My only wish is that Ofer would finally allow Chris to release his engine, giving fans the opportunity to recreate their vision for Sonic Xtreme in full (as most of the other required assets are already available). Maybe then some enterprising team might even be able to attempt a conversion... the scope of homebrew programmers has come a long way in recent years, as seen by the ongoing restoration of Biohazard 1.5 for the PlayStation!
Interesting. What is this restoration you speak of...?
