- Notes on Doom V1.2 compared to Doom v1.1.
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
- Last Change: 23/3/94
-
-
- First off, please tell me if these instructions contain any
- innacuracies!
-
- Anyway...
-
- Some things about v1.2 compared to v1.1 (NOT new feature descriptions,
- just general information):
-
- 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: ig 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. Some have said even these do not
- always work, either, although I found them to be ok.),
-
- 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 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..
- Id is working on this problem just now. 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."
-
-
- An apology if you are having keyboard control problems:
-
- Unfortunately, if you are someone who is experience character-
- control problems using the keboard, then I am sorry to say that I do
- not have any information on how to lessen such problems at this
- time.
-
- Hopefully, however, the rest of the above information will be of
- some use.
