Oh yeah, that would be a godsend. JLukas and Geiger would tear it to pieces. I'm stoked that drx has had so much success finding stuff like this. I've got the Sonic builds now, but lo and behold, my Genecyst emulator (let's see, downloaded in 1999) isn't working with Windows XP. Time to find a new one.
Many people here would suggest Kega Fusion. Me personally, I use Gens+. It's up to you, but they're both pretty good emulators.
Thanks for dumping those all Sonic prototypes and I was suprised that the protoypes included ones that Power Ranger games for Mega Drive/Genesis and Game Gear I even I want to thank for that too since it makes a Super Sentai/Power Rangers fan like me very amazed and happy.
Some people seem to take things for granted. As he puts a lot of his own money and time for acquiring these prototypes, he's not beholden to release any more. Basically, be patient and take things as they go.
Well, from what I had read it seemed like he had most of them ready anyway, already acquired and whatnot. ...though it is possible that he'd still need to properly build some of them, which might account for the wait. That said, another tentative release date would be welcome. Even if it's six months from now.
