'Alternate Reality The Dungeon'

Alternate Reality: The Dungeon is listed in the database as being signature on track 1 with half of the track being bad data and the other half $AA bytes.

It's actually the encrypted custom DOS, just like V-Max's track 20. It loads over the entire $000-$600 drive memory area (yes, right over all of zero page). Basically like restoring a snapshot of the drive state which I'm guessing caused instant problems for any drive not 100% 1541 compatible. Self-modifying decryption routines that dump drive code in the stack area ($100) and command buffer ($200) as well as the regular buffer areas. It's actually quite impressive and the length of the data being spooled in therefore requires 8k drive RAM or a parallel cable to duplicate.

It identifies itself as BOSS DOS:

BOSS DOS (C) COPYRIGHT 1986 BY INTELLICREATIONS, INC. WRITTEN BY JOHN BUTROVICHV2.4

A quick google search on this turned up an interview with the guy back in '87 where he states that it stood for "Balls Out Super Serial DOS". Apparently the guy is still active in the games programming scene:

Interesting stuff.
