ATX, a mod for the PC game Trespasser, Dreamworks Interactive (2023)

This page is the official page of the Trespasser mod ATX Trespasser. It will contain any new updates and other notes related to it. You can get any help related to Trespasser atTresconBulletin Board. I signed it as "Big Red". NOTE: These downloads are available for experimental purposes only. Use at your own risk [but report bugs or they won't be fixed].

ATX is a mod for DreamWorks Interactive's PC game Trespasser, designed to provide the game with a number of additional features, including new code, dinosaur options, graphics optimizations, technical assistance, and most notably level design addons. It consists of a DLL, a hack executable and some other basic files. It has been recently updated (version 2.00+).

In particular, ATX allows level designers to use additional ActionTypes in their levels and combine many new features with many old ones into one package. The new ActionType value is set using an external DLL, which automatically detects the associated executable after loading. This system allows updating a small DLL file without having to update the executable multiple times. New ActionTypes are programmed to use existing T-Script entries and are recognized as valid functions by Traspasser. All other functionality uses self-modifying code implemented by a DLL.

The list of included features is constantly growing. There is a list here, but I can never update it. For a complete list, you should check the ATX_README.htm file included with the latest ATX package (under the "Features" section).

Full documentation on new ActionTypes, tricks, and other features is provided, along with full FASM assembly source. As long as the end result is reasonably different from the source code, the source code is modifiable and can serve as a basis for others to gain trust. it doesyesFear of using, modifying, compiling, etc. ATX source. It's open for a reason. Much of the code has been reorganized in newer versions of ATX to help with this, with extensive use of FASM advanced macros, and an additional hacking guide (TEHG.txt).

ATX is generally tested for use with the following operating systems: Windows ME, Windows 98 SE (with and without unofficial updates), Windows2000 Professional with Service Pack 4, Windows XP Home, Windows XP Professional (s/SP1-SP2). However, generally only use Windows 2000 Professional with SP4 (with Update Pack 1) to test all new features. Later versions of ATX are also known to run on some versions of Linux (notably WINE).

Note that this is a beta-only mod. There are many more bugs/mistakes/bugs, though they may not be obvious at first. Depending on your system, it might work differently and you might run into issues. If this is the case, I would appreciate being notified of such issues via the Tresco message boards or email. Include a description of the problem, the type of executable and your operating system, the error.log and/or ATX_LOGFILE.txt log files, and screenshots if necessary. However, please read the list of known bugs beforehand to avoid submitting previously known bugs. Thanks.

Detailed installation process

For detailed installation instructions, or if you are upgrading from an ATX version earlier than 2.00, see the installation section of the ATX_README.htm file in the latest ATX main package.

Consider the following potentially serious problems before running ATX:

Here are some of the most common Trespasser/ATX problems and easy solutions:

Game settings or Traspasser/ATX executable errors on launch

-> In Windows XP, right click on the executable (or setup95.exe, trespass.exe, ATX Trespasser executable or any executable EXE on the Trespasser CD), select Properties, select the Compatibility tab, select " In Compatibility mode:", select Windows 95 or Windows 98 from the drop-down menu, and click OK. With a few extra steps, this is also possible on Windows 2000 (search MSDN for Windows 2000 Compatibility Mode).

Intro video plays too fast, choppy sound, fatal error when launching ATX or game executable

-> For this, you need to download and unpack ATX, and you should try to run it at least once. Open ATXconfig.ini (in Notepad), find the [Troubleshooting] section, set DisableA3DdllDetection=1 instead of 0 and save the file. This error is caused by the presence of an incompatible A3D.dll file in the system folder. This fix just prevents it from being detected by intruders. NOTE: This will disable 3D sound.

The configuration file ATXconfig.ini is missing or cannot be found

-> Run the ATX executable once, then quit the game. ATX only creates this file on first boot (this makes updates easier).

What files does ATX need to run?

-> At least, in the Trespasser folder you should have the ATYPEX.dll file, the trespassATX2.exe (or other ATX patch executable) and the MAPS folder (containing everything in the latest atx2XX.zip package). ATXconfig.ini should also be created after first boot (if not, ATX uses default configuration).

User-created levels become garbled after restarting, loading a savegame from the same level, or selecting "Restart Level"

-> Select the ATX "Disable Fast Reboot" option in the main menu of the game. This helps fix some issues with scene files and saves games that don't load properly. NOTE: Some levels with specific issues such as unstable terrain will not work properly with this feature.

The game randomly crashes when there are too many things on the screen or after the level loads

-> You may have set the drawing distance too high. Go back to the video options menu and swipe it all the way to the left. Also, try enabling hardware rendering if it is not already enabled (use the "Choose a new video driver" button). Some layers do not work properly in software mode.

Not available for Windows Vista or Windows 7

-> Unfortunately ATX has not been tested to work with Windows Vista or Windows 7.
