I think the links got broken because of the forum update.
I've reuploaded the files and attached them to this post.
MINECR999.8xp is the executable (MirrageOS iirc), MINESRC0.8xp is the main source file, and GENWRLD2.8xp is the world generator source.
To compile, make sure that you have both the main source and the source for the world generator on your calc, and compile MINESRC0. I think I used axe 1.0.3 for this game, but I doubt that I used anything version specific, so it'll probably work in most recent axe versions.
