pak0 is a file that you need of the original quake cd or you now can download, you need to look on the "Read me" document to find out were to put it
PAK Game File Required==
The software contained in this archive is only the engine which processes a game file (PAK). You must obtain the shareware Quake PAK file, named PAK0.PAK, which has been compressed with the gzip utility (
http://www.gzip.org). The compressed PAK0.PAK file's size is around 8.5 MB. This file can be downloaded directly from
http://www.pocketmatrix.com/pocketquake/download.html. If you own the registered version of Quake, then you may copy the registered pak files from your Quake CD-ROM onto your device if they will fit (storage card required). The registered pak files can also be gzipped to substantially reduce their size (which greatly increases game load times).
=INSTALLATION==
This software currently contains no installer - you must manually copy the files onto your device. This is a very simple process:
1) Connect your Pocket PC to your desktop PC, and make sure that the ActiveSync connection is patent.
2) Press the Explore button on the Microsoft ActiveSync window, then double-click the My Pocket PC icon.
3) Create the directory /quake (note: do not create this in My Documents, create it in the root of "My Pocket PC"), then create a directory within quake called ID1: /quake/ID1/
4) If you retrieved the pak0.pak.gz file from our website, then the file will be zipped (pak0.pak.gz.zip). This is necessary because some web browsers were automatically decompressing the .gz file, which resulted in a 24 MB file. If the file is zipped (ends with .zip), then you need to extract the file ONCE, so that it is pak0.pak.gz. Note that Windows Explorer on your PC is configured to "Hide known file extensions" by default. In other words, your PC may tell you that the name of the file is "pak0.pak.gz" when it is really "pak0.pak.gz.zip". You can verify that actual type by pulling up the file's properties, or by changing the settings of Windows Explorer so that file extensions are not hidden.
5) Copy the pak0.pak.gz file into the /quake/ID1/ directory you created on your Pocket PC.
6) Open up the PocketQuake ZIP file you downloaded (using WinZip or similar zip software), and copy the files to the following locations on your Pocket PC:
7) Copy the autoexec.cfg file into the /quake/ID1/ directory you created in step 3. (Note that this config file is REQUIRED for proper sound production, and is also needed to make use of 999's custom control layout).
8) Copy GX.DLL into the /Windows/ directory of your device. That file will already be on your device if you have installed other games in the past. In that case use whichever version is the most recent.
9) Copy PocketQuake.exe onto your device. Placing it in /Windows/Start Menu/Programs/Games will make it easy to access.
10) Run Pocket Quake!
This should sort you out :approve:
