CRC32 hypothesis explored/tested/examined:

According to my CRC32 routines the CRC32 for pak0.pk3 is:

1811190257 (in decimals)
6BF491F1   (in hexadecimals)

xor-ing with 02261994 gives:

69D28865

Not even close to the reported checksum by the quake3 executable.

The value 401698992 cannot be a file offset, because that would mean file 
offset 401 million... the file is only 45 million bytes.

(Maybe it's a simple checksum ?) I shall try that next.

Is a "!" a valid symbol in the file-name for the demo program?

Checksum hypothesis tried:

Constrained to 32 bits.

Checksum would be: 1677152593 (assuming extra bytes would be padded)

Otherwise if ignoring last few bytes:

Checksum would be: 1388822617

This indicates what the last bytes could have been:

1677152593 - 1388822617 = 288329976

File size is:

46,853,694

46853694 mod 4 = 2

Last two bytes appear to be zero so they don't add to checksum.

So doesn't matter anyway.

Let's see what happens when these checksums are inverted like internet 
checkusm

xor FFFFFFFF if I am not mistaken ;)

First method: 2617814702
Second method: 2906144678

Still totally different ?! ;)

So this is probably not it ?! ;)

Bye,
  Skybuck... :( :)

> Is a "!" a valid symbol in the file-name for the demo program?

Yes I think so...

I have other demo files with other names (just letters and numbers) and they 
are also not working.

Bye,
  Skybuck.

I just discovered something slightly funny:

Apperently it is possible to add empty files to the zip file.

I added a file called "b"

And it worked... Quake 3 started.. as long as no other pk3 files present.

I also tried truncating larger modified pk3 files but that didn't work.

Maybe quake 3 arena demo only checks for correct file size ?

Who knows ;)

But my bet for now is on some kind of crc32 check...

Maybe just the crc32 from the zipfile itself (though the sources indicate 
otherwise... some kind of special structure ? source code: 
"pack->checksum" ).

I tried looking at the pk3 file with a hex editor maybe I should take a 
closer look sometime ;)

  Skybuck.

Weak trolling attempt. 
You overplayed the stupid part.

Ok,

Little update on the truncating idea (matching file size):

As long as no other modified pk3 files then it says:

"Can't load default.cfg".

So it no longer says corrupted...

So truncating might get it a step further or maybe vice versa me not sure ?

So maybe this could work:

Stuff demos into it.. make pk3 smaller somehow... maybe use compression ?

Or maybe remove some unnecessary file... and then simply pad it with bytes
to make filesize large/the same...

Maybe that will work... since maybe then the zip is complete...

now is partial/sections missing... which could explain this new message... 
or maybe not ;)

Bye,
  Skybuck.

Some more experiments:

When I delete atari.cfg from the pk3 which is 41 bytes

It says this:

Corrupted pak0.pk3: 2760330299

Then when I add test.txt which has 41 bytes:

Corrupted pak0.pk3: 1449115608

So it does seem to change somewhat.

Bye,
  Skybuck.

Another little strange thingy happened... my graphics resolution was 
lowered/changed... don't know why...

Almost seems as if it stored settings inside pk3 but probably not...

It probably resetted it because of the bad stuff etc ?!

Hmm...

Bye,
  Skybuck. 

Something else weird happened as well.

My hud is now gone ?!?

Like the health indicator ammo indicator ?!

Checked everywhere in menu's no where are options.

Very strange !

Bye,
  Skybuck. 

Even the score display is not working anymore ?!?!?

Totally strange.

For now I will assume it's some kind of wacky driver bug or something.

I hope not a date/time check or so... since I copied the original pk3...

I will try to use original pk3 and see if it returns to normal.

Nope... totally strange.

Fucking game.

Bye,
  Skybuck. 

Ok,

The settings responsible for the hud is in the q3config.cfg:

seta cg_draw2d "1"

Apperently quake3 resetted itself and forgot to re-enable this settings
or maybe it put it off for safety or so ?

Weird anyway  ;)

Glad it's back on ! ;) :)

Bye,
  Skybuck.

Goto "DEMOS" in the main menu.  Your demo should be listed there.  Select
it.

Against bots?  Um, I'm sorry to say, that's not going to happen... unless
you manage to impress non-Q3A players.

Did you install onto a legitimate copy of Q3A?...  Did you apply the final
Q3A update version?...  q3pointrelease_132.exe

> The recording is stored in a file called: SkybuckPlaying!.dm3

The extension should be something like:  .dm_68

That's dm underscore two_digit_number.  Look under "DEMOS" in the main menu.
Your demo should be in the "Quake III Arena\baseq3\demos" or maybe it's just
"demo" singular directory.  If you set  g_synchronousClients "1" and used
"record <demoname>" and "stopdemo", I don't understand why your demo was
incorrectly named and/or misplaced.

I don't think you need any...

I've got no problems recording and replaying, but I updated from a legal
version of Q3A.  Is that the difference?

That's because .PK3 's are just PKZIP's with the .ZIP extension changed to
.PK3.  (Hint: Does this clarify your CRC32 issue any?...)

These settings are to allow modified dll's.  I'm not sure about modified
.pk3's.  They should be entered into the console or q3config.cfg file (in
baseq3 directory):

com_blindlyLoadDLLs "1"
seta vm_ui "0"
seta vm_cgame "0"
seta vm_game "0"


I'm not sure why you're having problems.  It might be they restricted the
demo.  Or, it might be that you've got a bad install.

Because this is Usenet, and some people, er... "think" they better have
a few groups too many than one too few.

Yeah Demo is too restricted it needs to be cracked so it can play externally 
stored demos and not just the demos stored in the pk3 file ! ;)

Bye,
  Skybuck. 

What you do is set up your Phone Movie camera, (You'll need good
memory though,) and record it to your phone. Then Bluetooth it over or
serial cable or infra red it to computer. As a 3gp or mpg or mov file,
you can download it to U-Tube that way. I'm not sure if it will accept
3gp file though so check what formats it can do B4 going down that
path and if a converter is available if it doesn't.

I took a movie from U-Tube on my phone which turned out pretty good so
is same but in reverse. Hope this helps as may be a way to do easily
if nothing else works ok?
Paul.

Not ok lol,

Thanks for tip, but I want this demo to be played lol :)

It's ok... if it's not cracked then I could get quake full... and convert 
the demo.

But it's more fun/interesting to crack the demo.

  Skybuck.
