RUNNING REGISTERED QUAKE IN LINUX

Here's how I ran registered quake under Linux.  I suspect not everything
will work, but I played through about half of e2m1, and it seemed okay.

Here's what you need:

. Working Linux Shareware Quake 0.91 setup (the tar says 0.91, the
   game says 0.92 when you run it) from ftp.lek.net:/pub/linux/quake/
. Registered DOS Quake -- 1-800-IDGAMES
. qeu from
  ftp://ftp.cdrom.com/pub/idgames2/utils/bsp_pak_tools/qeu03.zip
. Python

First, put this script in bspver.py <<EOF
#!/usr/local/bin/python
from sys import argv
for i in argv[1:]:
	try:
		f=open(i, "r+")
		c=ord(f.read(1))
		d=ord(f.read(1))
		print "%s was version %d" % (i,d*256+c)
		f.seek(0)
		f.write(chr(28))
		f.write(chr(0))
		f.close()
		print "Converted %s to version %d" % (i, 28)
	except IOError, what:
		print "Failed to convert %s: %s" % (i, what)
EOF

Unpak registered's id1/pak1.pak into the id1 directory of Linux
shareware quake.  For me, the command was
 /usr/src/qeu/unpak -d /usr/src/quake/id1 /dosc/games/quake/id1/pak1.pak

Then, change the version of the bsp files:
 python bspver.py /usr/src/quake/id1/maps/*.bsp

Finally, run xquake or xf86quake.  You'll need to adjust the gamma
setting on e2-e4 maps, since the levels appear overly dark compared to
e1 or e2-e4 in DOS.  I suspect this is related to the "overbrighting"
introduced in 1.00.

And, the step after finally is to send mail to johnc@idsoftware.com
telling him how important having a real version of registered linux
quake is to you.  Dave Taylor, now at crack.com, is willing to do the
work, as he did with qtest and the shareware, but wants Carmack to
give him credit for his work.  I don't know the whole story, but I
think that John Carmack is the one who needs gentle pressure to get
Linux Quake moving again.

Please let me know if this works for you, if my instructions can be
clearer, etc.  You can reach me as jepler@inetnebr.com.

Other Linux Quake tips:

If you can't get sound (quake crashes without -nosound), try setting
these environment variables:
 QUAKE_SOUND_CHANNELS=1
 QUAKE_SOUND_SAMPLEBITS=8
 QUAKE_SOUND_SPEED=11000
In some recent versions of the kernel, stereo sound is incorrectly
detected and causes an error in Quake.
