Here's a random proto track and an newly-ripped E3 trailer (@60FPS) from Mega Man X5

Three months!? Gosh, I've been out for a while.

I've been in the mood for prototype/unreleased games again lately. This time, I've taken a listening to a track I've ripped and uploaded on YouTube a year ago, from a prototype version of Mega Man X5 dated May 1, 2000.

The biggest difference to note about this track is in the middle. The first fifty seconds are consistent to the final version, but after that the main verse (or bridge, whatever's the right term for it) becomes different. If you ask me, this version emits the vastness of space much more than the final one (though the stage actually takes place in a planetarium, surprise suprise). Out of all the tracks in the proto, this one is my favorite.

The prototype itself contains a large number of rudimentary elements indicative of its progression into it's final form, all of which you can find them documented at the Cutting Room Floor. The US preview trailer, unveiled at E3 2000 convention in Los Angeles, CA that year, appears to be from this build of the game.

If you want to see the whole VHS rip in it's entirety, you can find it here and reminisce about the old days when Mega Man (and Capcom) was a bigger brand than it is today.
