6.1 Are there any cheats or trainers? Can I skip a level?

There are no cheat codes. There are a few trainers available from the internet, for example iMSDOX produced one to give Honor Points, maximise unit and troop control points, and increase town population. The file can be found here, http://www.gamewinners.com/DOSWIN/blpraetorians.htm .

The same site also includes a saved profile with all campaign levels unlocked. This can be achieved manually. From jaycw2309: "Go to your profile directory in the /My Documents/Praetorians folder [see Where are game save files stored? below]. Open up the .USR file [in a text editor such as notepad] (make a copy of it if you are worried). In there you'll see a section under 'Flags_misiones'. This is where it lists which missions you've done, and on what difficulty. The top 4 are the tutorials, so only have 1 difficulty, all you need to do is change the 0 to a 1." For example:

*FILE_FASE "Misiones\ZZZ_Rio Arar.mis"
*DIFICULTAD
{
*VARIANTE 1 0
*VARIANTE 2 0
*VARIANTE 3 0
}

Edit to:

*FILE_FASE "Misiones\ZZZ_Rio Arar.mis"
*DIFICULTAD
{
*VARIANTE 1 1
*VARIANTE 2 1
*VARIANTE 3 1
}

6.2 Where are game save files stored?

In .../My Documents/Praetorians. On Windows 9x this folder normally resides directly on the main hard drive. On Windows 2000/XP it can be found within the user directory, for example "Drive:/Documents and Settings/[Username]/". Profiles and save games are stored in separate sub-directories. Copy the contents of both sub-directories when creating a backup.

6.3 Can the resolution be changed?

Yes, but not higher than 1024 x 768. Resolutions can be set under Options--Video Options.

6.4 How can I take screenshots?

Print Screen works for most people - simply paste the contents of the clipboard into an application such as Paint. Random suggests using Fraps ( http://www.fraps.com/ ) which allows a key to be bound in order to capture a screenshot.

6.5 Are there any custom or multiplayer siege maps?

Officially no. However, campaign siege maps have been hacked to create multiplayer/skirmish versions, thereby allowing multiplayer sieges. At the time of writing these are in the early stage of development and replace existing skirmish maps - read the accompanying documentation carefully. Jason Novak's original siege map based on Tutorial III can be found at http://www.merlinsoftware.com/praetorians/fortress_siege.zip . Others can be found here, http://www.geocities.com/klanpharaoh/dwnloads.html .

6.6 Can I play as Greeks?

Yes. Download and install aWaKeNiNG's Imperial Mod from http://www.mod-project.com/ . The modification adds Greek units to existing multiplayer and skirmish maps. The campaign remains unchanged.

6.7 Is there a map editor?

Officially no. Pyro wrote one for internal use, but at the time of writing this has not been released. However, Jare (Praetorians developer) has made available enough information on the file structure to allow some simple map editors to be developed. Such an editor and documentation could be found here, http://clanpharaoh.com/paulus/ (now offline). A alternative editor is being developed here, http://www.mod-project.com/ .

6.8 Are there any guides to modifying the game?

Yes. Tom Sikking has a comprehensive guide here, http://home.quicknet.nl/qn/prive/jsikking/Praetorians/Guides/v1.0.doc (also see http://www.freewebs.com/pyrostudios/guides.htm ), and a guide to changing the amount of units - http://home.quicknet.nl/qn/prive/jsikking/Praetorians/Guides/Units.doc . Jason Novak described the basics of modifying maps, along with an explanation of file types and terminology. It can be found here, http://www.merlinsoftware.com/praetorians/tutorial/ . Various modding tools could be downloaded here, http://clanpharaoh.com/paulus/ (now offline), including a 3D Studio Max plugin for importing PBA files and a PTX converter.

6.9 Can I open .pak files?

Pak files are the format the game uses to store resources. Jare writes: "Praetorians pak files are actually ZIP files; however, some of them are encrypted by XORing each byte with the value 171 (0xAB). Either type will be recognized automatically, in fact, you can see that the patch datafiles (and some of the original pak files) are not encrypted. The only important thing is that sound files are in their own pakfiles, NOT encrypted and NOT compressed." Jason Novak's utility decrypts encrypted pak files. It is available here, http://www.pctechzone.com/praetorians/pak.zip .

6.10 Can I extract music from the game?

Yes. Shamaani writies: "Extract the music.pak file into a new folder [see Can I open .pak files? above], you will get .OGG files. Use Winamp to read the .OGG files or convert the files with an OGG2MP3 program."

6.11 I can't connect to an online game. Any suggestions?

Ensure you are using the latest patch - all players must be running the same version. Zeta writes: "You need to configure your router so that it redirects DirectPlay ports to your computer. Try with ports 2300-2400 and 47624." The same ports (2300 and 2400 and 47624) apply to firewalls. For help with firewalls in Windows XP, see Microsoft Knowledge Base Article - 283673 "Enable or Disable Internet Connection Firewall in Windows XP" - http://support.microsoft.com/default.aspx?scid=kb;en-us;283673 . Pauldls writes: "GameSpy says: Arcade needs the following TCP ports open in order to function: 6667 (IRC), 3783 (Voice Chat Port), 27900 (Master Server UDP Heartbeat), 28900 (Master Server List Request), 29900 (GP Connection Manager), 29901 (GP Search Manager), 13139 (Custom UDP Pings), 6515 (Dplay UDP), 6500 (Query Port)."

6.12 I have video/display problems. Any suggestions?

The three most common solutions are: (1) upgrading drivers (often said, but it does solve many problems), (2) updating DirectX (to at least 8.1), (3) uninstalling any demo version(s) and then reinstalling the game (the two versions overlap slightly with negative results).
