GLHeretic V0.4 [29/05/99]
-------------------------

GLHeretic is an OpenGL port of Heretic for Win32.
GLHeretic compiles with Microsoft Visual C V4.0 & V5.0 compilers.
Minimal requirements are a Pentium & 32Mb of memory.
For fast rendering, a 3D accelerated card is needed (OpenGL compatible).
It runs fine on a P200 with a voodoo1 3dfx card.

GLHeretic has been successfully tested on (with a decent framerate):
 P200     + 3dfx voodoo1 (WinNT, Win95)    [V0.4]
 PII300   + ATI Rage Pro (WinNT)           [V0.4]		(transparent sprites are invisible)
 PII400   + 3dfx voodoo2 (Win98)           [V0.3]
 K6/2-350 + I740                           [V0.3]
 PII266   + Riva TNT (Win98)               [V0.1]
 PII450   + Savage 3D (Win98)              [V0.1]
 K6/2-300 + Riva TNT                       [V0.09]
 K6/2-300 + ATI Rage 128                   [V0.09]
 PII450   + G200 (Win98)                   [V0.08]
 PII266   + Riva 128 (Win98)               [V0.06]

Note for 3Dfx users:
--------------------
!!! Be sure you have installed the OpenGL beta 2.1 drivers from 3Dfx !!!
Here how to install them:
1- Download from: http://www.3dfx.com/view.asp?IOID=26
2- Run opengl2.exe and uncompress it in a temp directory.
3- Copy 3dfxopengl.dll into your Doom directory.
4- Rename it into opengl32.dll.

Quick Start:
------------
Put GLHeretic.exe in your heretic directory (shareware or commercial version).
3D PCI cards < 8Mb users: launch VOODOO1.BAT
3D PCI cards > 8Mb users: launch VOODOO2.BAT
AGP users: launch AGP.BAT

Important note:
+++++++++++++++
 When you start GLHeretic, there are informations displayed in a console.
 If you play fullscreen or with a 3Dfx, you may miss this console. You can
 redirect it to a log file by using: GLHeretic ..your command line switches here.. > log.log
 If you want to send me any problem, please attach this log.log file to your e-mail.
Screenshots:
++++++++++++
  You can make screenshots: use -ravpic & F1 key like the classic Heretic.
  A RAW file (GLshot.raw, flipped 640x480 RGB format) is generated.
  If you have a problem and want to send me a screenshot, please convert it to JPG (with PaintShopPro for example).

Joystick issue:
+++++++++++++++
If you don't have a joystick plugged in your computer, be sure the use_joystick value is set to 0
in your hereticrc.cfg. If it doesn't, you could experience slowing down !

What's new in Version 0.4:
--------------------------
- Mouse look: Invert mouse Y axis:
	In doomrc.cfg, use: "invert_mouse 1"
- Bug in floor raisng/lowering fixed (found in DoomGL)
- Optimisations: the few fps lose in look up/down should be recovered !
- Screen width/height now correct in fullscreen mode.
- "PAUSE" displayed when game is in pause.
- Sound crash fixed (when using the phoenix rod with tome of power for example).
