               Notes on Doom V1.2 compared to Doom v1.1.
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Some things about v1.2 compared to v1.1:

(see section 5 for info on the psychomouse bug and keyboard control
problems)


1. Saved games from v1.1 are NOT compatible with 1.2. This ALSO applies
   to .lmp demo's made under v1.1. In both cases, this applies to the
   Shareware version AND the Registered version. ALSO: if you are
   reading this BEFORE using a 1.2 patch file, be warned that all the
   old saved game positions will be destroyed, so take backups if you
   want to keep them!

2. The cheats still work, but not in Nightmare mode (only idclev and
   iddt still work in Nightmare mode).

3. I have been informed that Doom v1.2 will NOT run under OS/2 if you are
   trying to use a soundcard. If this problem occurs for you, turn off the
   sound using the setup program.

4. v1.2 contains some new secrets! One is on E1L1. Where the others are, I
   will not say... :)

5. v1.2 has some nasty bugs cencerning the control of your character.
   If you have a PS/2 mouse setup, this is almost certain to occur, but
   it is far more widespread than this. Symptoms: your character goes
   crazy, shooting all over the place, moving erratically, the etc..
   This problem has been _fixed_ in the final release of registered Doom
   and Shareware Doom (version 1.666).

   You can ftp Shareware Doom v1.666 from many ftp sites. Email me for the
   detailed help file on how to ftp Shareware Doom v1.666).

   Some Doom ftp sites, the main one first:

     ftp.orst.edu:/pub/doom

   Others:

     ftp.iglou.com [192.107.41.3] /doom                  Kentucky


     ftp.uni-erlangen.de       (Europe)
        Old ocf mirror directory is in /pub/pc/msdos/games/ID/ocf
        /pub/pc/msdos/games/ID/doom-stuff is now a mirror of infant2


     ftp.luth.se               (Sweden)
        Look in pub/doom       (very fast transfer rates if you're
                               close. I've had 100K/sec here in UK
                               from this site. Averages about 25K/sec).


      ftp.cdrom.com [192.216.222.5] /pub/doom            California


      nctuccca.edu.tw [140.111.1.10] /PC/games/DOOM      Taiwan


      ftp.sun.ac.za [146.232.212.21] /pub/msdos/doom  (weekly?) South Africa


      ftp.demon.co.uk:/pub/ibmpc/games/id   for the 1.666 patch files.

   Look in the ...doom/id directory. Patches to upgrade v1.2 to v1.666
   (both registered and shareware) should also be in this directory on the
   above sites.

   In the meantime, here is some extra info about the bug and a temporary
   fix if you can't, for some reason, get v1.666...


   As someone who emailed me about the bug said:

   "It's not limited to the PS/2 mouse or even to the mouse in
   particular. There's some bug with the input device. The bug can
   happen with *any* mouse, or even if you are playing only with the
   keyboard."

   However, PS/2 mice are most prone to the problem.

   Running Doom from windows is apparently one way to solve the
   problem. I now have a help file available for anyone who wishes to
   know how to run Doom under windows. If you would like a copy, please
   email me.

   One definite way to fix the problem (if it's the mouse that's acting
   crazy) is to use an adaptor to plug the mouse into the serial port,
   or just use a serial mouse. This method was successful for me, and
   has been for many others as well.

   Some people have found that using a different mouse driver solved
   the problem, or at least greatly lessened it. One mouse driver
   particularly mentioned a lot is the GMOUSE mouse driver. This driver
   can be obtained via ftp from:

      oak.oakland.edu

   in the directory:

      /pub/msdos/mouse

   and the file is called:

      gmous102.zip

   Don't forget to enter 'bin' before you enter 'get'!!

   For those without ftp, I can email you the driver.

   Someone said to me that this driver works best when configured for
   two button mode, in that the bug is still present when set for three
   button mode. Thus, if you're used to using a 3 button mouse, try (a)
   using just the left and right buttons, (b) setting the driver for a
   two button mouse, and (c) maybe use ALT for strafing instead of the
   middle button (or whatever it was that you used the middle button
   for).

   As to why the PS/2 mouse setup is particularly problem prone, I
   spoke to someone who knows a lot about pc's, and was invloved with
   their design years ago. He said:

      "Also, PS/2 mice are a marginal idea at best--they suffer from
       many of the same problems as do PC joysticks--the interface
       was built with a 6MHz cpu in mind -- not 33/66MHz PCs!
       There are several areas were improper matching of impedance,
       etc. can cause various forms of aliasing effects to occur."


   Keyboard control problems:

   About the only tip I have here is this:

       - if your character goes nuts, try pressing the key that would
         normally be used to cause whatever the character is doing; e.g. if
         the marine starts to run forward out of control, people say that
         whacking the 'forward' key should stop the uncontrolled motion.


Hope this helps.
