NFL 2K1 & 2

[Excalibur007]

Does anyone know how to downsample the audio DAT file in NFL 2K1 and 2K2?

Ahhh...I've been searching for this answer myself for a long time....

Anyway open Audio.dat (181MB) with Goldwave version 4 or 5
( http://www.goldwave.com ).
The format will not be automatically recognized, so you have to manually select to open the file as Dialogic VOX - ADPCM 4 bit, Mono with a sample Rate of 11025 hz.

Now play it and you can hear all referee calls, stadium announcer, and in-game commentary by Dan Stevens & Peter O'Keefe, unfortunately the sound quality isnt perfect so some hiss noises are audible. My guess is that all the audio files are somehow linked & packed inside the big .DAT files, so I suppose someone with some free time would need to code a utility to unpack/pack these files so they can be properly modified, or perhaps create a plugin for Goldwave/Cakewalk/(insert your favourite audio program here) to enable them to decode & edit these files.

audio.dat (181 MB) - In-game commentary, (9 hr track length)

chat.dat (20 MB) - Same deal as audio.dat but contains stadium music tracks, crowd noises, etc. You'll actually be able to listen to fans & other players shouting at other players to wake up, get their act together, etc..... some are rather funny... (1 hr track length)

teams.dat (575KB) - Same deal, but it only has the announcers voice calling all team names, Home Team, Visiting Team, 49ers, Bears, Cowboys, Southwest Alumni, NFL, Superstars, etc. (1:40 min track length)

players.dat (19.8 MB) Announcers calling player numbers, i,e: Number 73, Number, 16, all the way from Number 99 to Number 0. It is then followed by all player names, Johnson, Smith, Aikman, Owens, Favre, etc... (1 hr track length)

The following dat files don't appear to have sound info on them, judging by their names I think they could have textures or models, but this is only speculation on my part.

faces.dat
helmetlogos.dat
logos.dat
port.dat

You could try and donwsample the files and see if the game runs, I might give it a try the next few days, as I'm testing some hexediting on that game's BIN files.

I tried this on *.dat files from Echelon's NFL2K2 release, so if you are opening the files from your GD-Rom the sample rates should be higher

WoW!! great info about the big .DAT files. not that i'm going to mess around with them, but good info nonetheless.!!


thx

Well I feel completely frustrated about this game's sound & graphic files
I can't seem to find the right tool to work with them.....anyway here's some more info:


Additional files with sounds =)


Most Files seem to start with: “SOUN............awww...VCSD.”
And end with: “........?.6.....?.....?.2?..EXIT............ ”
When viewed with a Hexeditor.

Play them as Dialogic VOX - ADPCM 4 bit, Mono with a sample Rate of 11025 hz. (Except where noted......)

Additional in-game sound effects.

Fxa0.iff (416 kb) Crowd noises & referee whistles? (Hard to tell)
Fxa1.iff (404 kb) Crowd noises & referee whistles? (Hard to tell)
Fxb0.iff (252 kb) Shoulder pad noises, player grunts, moans, screams, etc
Fxb1.iff (248 kb) Shoulder pad noises, player grunts, moans, screams, etc
Fxb2.iff (250 kb) Shoulder pad noises, player grunts, moans, screams, etc
Fxb3.iff (239 kb) Shoulder pad noises, player grunts, moans, screams, etc
Fxb4.iff (237 kb) Shoulder pad noises, player grunts, moans, screams, etc
Fxb5.iff (248 kb) Shoulder pad noises, player grunts, moans, screams, etc


As00.iff – (25kb) Player huddle noises?
As01.iff – (22kb) Player huddle noises?
As02.iff – (26kb) Player huddle noises?
All the way to………Player huddle noises?
As59.iff – (25kb) Player huddle noises?

Hs00.iff – (87kb) Player huddle noises?
Allthe way to………….
Hs59.iff – (67kb) Player huddle noises?

Qb1cn001.iff – (36kb) Various Quarterback counts (16, 35, green, 45…..)
All the way to……………
Qb1cn100.iff – (38kb) Various Quarterback counts (16, 32, green 45, …..)

Qb1dsh1.iff – (22kb) Various Quarterback sounds (down…set….Hut… hut.)
Qb1dsh2.iff – (25kb) Various Quarterback sounds (down….set….Hut… Hut..)

Qb2dsh1.iff – (20kb) Similar to the above but with other voice.
Qb2dsh2.iff – (19kb) Similar to the above but with other voice.



Qb2cn001.iff – (33kb) Various Quarterback counts similar to the above with other voice.
All the way to……….
Qb2cn100.iff – (32kb) (33kb) Various Quarterback counts similar to the above with other voice.


Loadsnd.iff (86kb) The music that plays while a game is loading with the animated NFL2k2 logo & the football (Open it as Dialogic VOX – ADPCM 4 bit 22050 hz, the sound isn’t perfect but you can definitely distinguish the tune).
Since this file only has 1 music track I tried to open/convert it to wav with adx2wav, cinepack & AFS explorer but none of them were able to recognize the file... =(

Gameaudio.iff (478Kb) The first part would appear to be some sort of crowd boos, then some sort of player moans, then just loud static, and some unidentifiable sounds at the end.
File starts with: “SOUN...../..0...boo/..VCSD”
Ends with “...............g...g....g.CEXIT............”

chat.dir (33.8KB) The file itself doesnt seem to have any audio, but it appears to have the filename references to individual commentary files which I presume are located within chat.dat

This is a fragment from chat.dir when viewed with a hexeditor:

A..A2......>...02..>.......pa_musonce10.wav.pa_mus once09.wav.pa_musonce08.wav.pa_musonce07.wav.pa_mu sonce06.wav.pa_musonce05.wav.pa_musonce04.wav.pa_m usonce03.wav.pa_musonce02.wav.pa_musonce01.wav.pa_ musonce00.wav.

The more I analyze this game, the more I think those echelon guys really did their homework when downsampling the vast number of sound files.

Finally I did some testing by replacing NFL2K2's Loadsnd.iff with NFL2k1's file of the same name, and the DC plays the sound just fine, (I think NFL2K1's music is better....) I also did some tests with stadium files but that belongs on another thread....

Hope this helps,

I'll keep searching........
