A long time a go I could've sworn that a bin/cue of this was floating around the internet. There are some signs that it existed at some point and I believe it actually came from PACHUKA back in the day. I've been trying to locate it for a while now but I was wondering if maybe anyone from around that time still had a copy of it? I know it's a bit of a stretch, but maybe there's a chance someone still has it somewhere. The prototype apparently had debug enabled and a few unfinished levels. The last I've heard of it was when Pach still owned CulT (around the time of his Amazing Spiderman prototype write up) but I haven't heard anything about it since. It'd be neat to find it since we have almost every leaked Sega CD prototype up until this point, except for that one.
You definately should. I would like to see this prototype archived at hidden palace. "(Also as a side request that's not too important because I can't find evidence of it being distributed, but does anyone have a bin/cue dump Eternal Champions prototype for the Sega CD? Pachuka had a copy of this as well but I don't think it was ever distributed.)" http://assemblergames.com/l/threads/request-the-terminator-sega-cd-beta.64220/
