    Hi all lamers, hackers and all you people

who are now, after 3 years still eager to see what Mr. Carmack did to
Doom that it runs so quickly. Today (20.1.96) I happened to download a
programm called SnapShot 1.00 written by Joshua Jackson. This little TSR
saves screen shots of DOOM/DOOM II/HERETIC every 2 or so seconds. The main
idea was to 'see' Doom rendering engine in progress. We (me and Ped) liked
the idea very much and decided to improve the concept.

  Our Carhack (tm) (c) 1996/2233 works in this way:
You reboot Your machine (after You read this great doc), press DEL or
whatever to enter BIOS setup, set no CHACHE, and other options, which can
make the computer slower ! (of course remember, what You did toggle)
In other words: Make your computer as SLOWEST as possible.
Ideal speed for default setting is st. like 386/15 (non-cached).

Bypass all autoexec.bat config.sys or whatever to keep the memory clean
(in MS-DOS 6.x press F5 when You see Starting MS-DOS ... message).

Load Your favourite mouse driver (when possible, compatible with MS-DOS &
DOOM thing u want to explore). THEN load the: (whatelse?)
CARHACK.COM
And then run Your doom-thing game (as DOOM/DOOM ][/HERETIC).

WARNING:
 Don't forget, You have no WARRANTY that it'll work !!! If the doom freezes,
or reboots, or whatever, we are sorry ... Anyway, try to keep the memory
before using carhack totaly clear (just mouse driver).
NOTE: TSR doesn't unload itself... reboot to remove.

How to USE it?
 Select NEW GAME and let DOOM load itself completely. THEN, find your
 favourite total-complex-mega-infested-place and:
 1. turn off turbo
 2. use IDDQD (IDCLIP is useful too)
 3. press 'S' to slow it even more (hehe)

loop: (this needs a little practise and patience)
 4. CAPS lock clears screen
 5. RIGHT mouse button slows DOOM Ooooooh so much
 6. watch out! (and either hold rmb or don't move yer mouse)
 7. dec cx
 8. goto loop

Getting sick, huh ?

 9. to turn off "right-mouse-button-slowdown" move the mouse ...
    (it took HOURS of coding to enable this feature)
10. turn on turbo
11. quit doom
12. Ask Carmack why he overwrites all sprites to VGA????
13. send us E-mail
    ^^^^^^^^^^^^^^
14. goto 13 (at least 2 times)


FAQ:
 Q: Doom flickers and behaves strangely.
 A: This is normal (everything is under control and runs ok).

 Q: Doom freezes or drops to DOS or (i dunno whatelse) . What now?
 A: Reboot and retry.

 Q: Rendering is still fast!
 A: 1. Borrow your neighbor's crap for awhile.
    2. Disable all caches, turn off turbo and so on.
    3. Press 'S' to set timer to 500Hz and press RMB (Do it ALWAYS)
    4. Examine the sources (if you can code ASM) and change some
       constants (they're are commented to help you find them)

 Q: Black screen (after CAPS lock) and RMB forever??
 A: 1. Wait. (some 8-40 secs)
    2. Release RMB, move mouse, press RMB, release RMB, move mouse, pr.....
    3. else something f*ed up (reboot)

 Q: I still can't see anything that interests me.
 A: This programm was not intended for you, sorry.

 Q: I want to thank you, how?
 A: Send TWO E-mails to the addresses below.


Have fun!    Greetings: to Joshua Jackson !!! U made a great deal of work for
                        us !!!!!! Once more thanx ... Get more so cool ideas!
