#766 — OT: A few questions for Japheth and Q3A runs in DOS

Japheth,

1)  What stuff are you working on now?

2)  Do you have any plans to release another SVGAPatch for 16-bit color?
E.g., 640x480 16-bit? 15-bit?

3)  Have you seen Xeno86's work on KernelEx?  I think your work on HXGUI is
somewhat similar in nature.  E.g., have you two considered coding an OS
together?

4)  Has HIMEMX been fixed to scan for additional extended memory after a
block starting at 0x100000 has been found?

5)  Do you know that Quake 3 Arena executes correctly with HXRT+HXGUI?

It's not listed on your compatibility page:
http://www.japheth.de/HX/COMPAT.TXT


For Q3A in DOS, you have to use the software renderer and add some files
posted on BTTR.  I'm not sure about sound or networking.  I don't know how
to set up the networking for DOS.  I did test a sound card with DOS drivers,
but I couldn't get sound.  The video, keyboard, mouse, and gameplay is all
correct though, including the introduction video.  The only problem is a
grey box with black border displays on one screen which isn't part of the
game just after starting the game.

You need these files in HXDLL.ZIP the HXRT/HXGUI bin directory:
http://www.bttr-software.de/forum/mix_entry.php?id=10855

The system files recommended by Doug here do not seem to be needed.
http://www.bttr-software.de/forum/mix_entry.php?id=10642

First, do the normal HXRT and HXGUI setup, e.g., unzip, adding BIN to PATH
variable, etc.  Start a mouse driver and an LFN driver.  Run your MTRR video
set program.

You also have to set FILES=120 in config.sys, maybe 80...  None of the other
settings, like HDPMI=32 or DPMILDR=8 or 16, for HXRT or HXGUI are needed.

You start Q3A's software renderer with HXRT+HXGUI this way:

  DPMILD32 -g QUAKE3.EXE +set r_allowSoftwareGL 1

To get more than 1 to 3 FPS, you must do change many Q3A variables.
I get 50 to 70 FPS with HXRT+HXGUI.  I think the most important are to set
the following in BASE\Q3CONFIG.CFG (or wherever there is a Q3CONFIG):

  seta r_lastValidRenderer "GDI Generic"
  seta r_textureMode "GL_NEAREST"

I haven't gone through to determine all the needed Q3A tweaks to get 50-70
FPS with the software renderer and HXRT+HXGUI.  I know the FPS will be low
with normal texture modes, like GL_NEAREST_MIPMAP_NEAREST or
GL_LINEAR_MIPMAP_LINEAR.  I previously tuned Q3A for the software renderer
in WinSE and VBEMP in a DOS console window.

If you, or Rugxulo, have more information, please post.

I'm going to add support for PE binaries to jwasm.

No. If you're interested, I'll upload the source code ( but it is
Masm, IIRC ).

Yes and No. The problem is that Win9x doesn't run on my current PC
(incompatible graphics).

No. I guess this has to be done by someone else.

> 5)  Do you know that Quake 3 Arena executes correctly with HXRT+HXGUI?

No. I'll try. Thanks for the hint!

You mean the source code for your patcher?  That's nice, but not needed by
me.  Someone might want it though.  If additional patches become available,
it'd be useful.

If you know of other code regions in SVGAPatch that could be modified, i.e.,
writes to vga ports, or what various code regions do, that'd be good to
know.

If you've got correctly disassembled source for svga256.drv, supervga.drv,
vga.drv, or framebuf.drv.  That'd be great.  Copyright issues may prohibit
providing them.

I also found another patch to svga256.drv for vmware, derived from your
patch:
https://sites.google.com/site/chitchatvmback/misc

It modifies more stuff, and some of the same regions, but differently.

Do you know of any other generic video drivers compatible with Win9x?  I'm
aware of VBEMP.  It's pretty good but has a few problems, especially
scrolling.

I've been searching for something that allows NT's or XP's VGA.SYS
to work on Win98/SE.  There are many patches and fixes for it.

Why don't you ask about it in microsoft.public.win98.gen_discussion, or
post a question in the win-9x/me forum on msfn.org?
