I know there are numerous Sonic Heroes prototypes that have been found and dumped over the years. There's the Xbox/Gamecube E3 prototypes and the 10.8/11.18 prototypes. It's well-known that they have beta music files that have been found and documented long ago. So far, so good.
But then there's this. The 10.8 proto music link is not the one that bothers me, it's the "early Xbox proto" one. Which early Xbox proto is that anyway? A lot of the songs in that archive I can't find anywhere in any currently known and dumped prototypes, as they have songs like Egg Fleet and Final Fortress and what have you that clearly sound very different to any other prototype, and the final. As far as I'm aware, the only known Xbox prototype we know about is the E3 one, but it only has beta songs of Sea Gate, Seaside Hill and Rail Canyon unless I didn't look at it carefully enough (I made sure I did). So I have to ask: where did these songs come from?
To make things even more confusing and frustrating, there's this Sonic Cult forum thread I found dating all the way back to when Sonic Heroes was just released, and it seems that it already had these "alpha" ADX files up for grabs by that time. None of the links work anymore though, so I have no way to know if these "alpha" tracks are legit and match up to what's found in Retro's "early Xbox proto" archive.
So what I'm getting at is: if you somehow have a clue where these "alpha" ADX files came from (if it really is an "early Xbox proto," which one?), or at the very least happened to be able to download them at the time and preserve them on your hard drive to this day: please please share them. I like to keep nice and clean ADXs of any and all Sonic songs, and I just can't stand the thought that there were beta versions of these songs right under our noses that we all failed to notice and question their existence.
