   I Introduction
   --------------

   zDoom began to exist as Doom83.    Raphael Siryani,  soon joined  by
Alexis Guinamard,  and they started to make a BASIC demo of a doom-like
engine.    Then they moved to ASM,  adding enemies,   weapons and other
things,  and released Doom83 for TI-83+.     Then they released a TI-83
version  and  the  game  reached  the version 0.97c  after which it was
abandonned for more than one year.
   December 2003, I  though it  was time to continue this project, so I
started to worked on it from time to time.
   This version (0.12) adds enemy animations.
   You can report  any  bug  or  comment  on the TIFT forum [1] or on the
Maxcoderz forum [2].
   zDoom is released into public domain, so you can do whatever you want
with it, but proper attribution is always appreciated.
   (Don't play it on VTI because it is sluggish.)

This version is released on ticalc.org, we fixed a bug that appends

is now only for MirageOS.
SIZE : ~14500 bytes

2002/05/14: v0.97b
Addition of a menu, and options, only the adjustment of contrast
max works for the moment, but the adjustment of the difficulty and
the tremors of the screen will come quickly... Moreover, the bug
which crash some times while exitting is fixed.

interruptions of Ti-OS also, the play is more fluid, and
displaying is cleaner!

2002/05/10: v0.96
The so much awaited 83'-' version is finally functional! Moreover,
the division made in a table was replaced by another calculated,
the program thus lost 2500 bytes! Finally a bug which made display the
sprites several times on the same image was solved It thus doesen't
have there more the deceleration by displaying several items!

2002/03/20: v0.95
The side bar starts to be functional: the life and amo are now
displayed.
