The first 3 worked great but my edge enhancement was hacked together and Vegas dropped from 60fps down to a whopping 2fps. I did some tests where I just doubled all the pixels instead with no extra work at all and the emulator ran about 22fps. The edge enhancement mode looked neat, but I'm unsure how useful it will be at such low frame rates. I have an idea for speeding it up significantly, but my other tests show I'll be lucky to achieve 22fps. A lot has been updated since Vegas 0.92 so be sure to look at the updates document in the zip file.
Genesis games are really nice and the sound is really good now.
A lot of 32X games now run under Vegas and I can now start listing games that don't work instead of games that do work. I've made some changes to try and improve the performance, but no radical changes. I have some ideas for improving the frame rates on some computers. I found this on both of my computers. This was causing havoc when playing games and on Vegas.
