I have been allying with with Google translate and browsing some of the Russian forums. Altmer at some point passed a remarkable barrier with a proof-of-concept in his version of FreeDO.
Has anybody else looked at these screenshots? http://www.arts-union.ru/smf/index.php?topic=265.0;
Here's a copy of one:
Notice the resolution of the image, It's far beyond 320x240. In fact, these scenes are rendered with real polygons. This is similar to to remakes of Doom that use OpenGL rather than the game's original software rendering, like Doom Legacy. As for 3DO emulation, I think this is the holy grail. This would significantly improve any game that relied on 3D graphics. Of course, all those games relying on video or sprite graphics simply wouldn't receive any benefit.
These screenshots were from over a year and a half ago, though. I've pinged Altmer, and apparently he's still working on FreeDO (which is great news!). I'm intensely hoping that he allows me to help out, since 4DO is based off a version of the FreeDO code that definitely
doesn't include improvements like these.
I can't find a version of FreeDO that includes these improvements though. Is there a version floating around out there that I can't find?
