This file contains updated .SCN and .GRF files for the levels from the Build 55 release of Trespasser, to make them compatible with GeomAdd, TresEd and the retail Trespasser engine and its mods (ATX, CE, etc.).
After having copied the Build 55 level files and TPA files into a fresh retail (or demo) install of Trespasser, and having used fixOcclusion with the Build .pid files and TPAupdate with the Build 55 .tpa files, replace the original Build 55 .grf and .scn files with the ones contained inside this archive. It's recommended that you make a backup first, anyway.

This unofficial patch improves models viewing distance in all trespasser levels, except the TestScene level. Visual look is greatly improved, but it also takes a hit on framerate.
Note: Alternative use the CE patch instead. For vanilla/patched version.

This patch will update your game to v1.1 (117). This update includes update for the Trespasser executable and level files.
Note: This patch will add a registry entry to the registry and a folder to your Trespasser installation. The registry entry is made to the game will know where to look for the patched level files. If you're modding Trespasser, this can become a problem since the game will load the files in the patch folder first. The changes to the levels are minor, and be found HERE. If you want the updated level files without the folder, download the "Trespasser Patch v1.1 Level Fix" instead, and replace the level files in your TresCD/data folder (after doing a hard-drive installation).

Thank you for keeping this game alive! I remember when it came out as a kid and it was fantastic! brings back old memories! Do the new patches allow game play on new systems without rapid acceleration?
Hi, Joshua. If you’re referring to 3d cards (hardware acceleration), the patches will work just fine with or without. I recommend Big Red’s atx patch as it adds new cheats and you can up screen resolution and quality.
Thanks Rebel! Much Appreciated 🙂
Thank you so much for making this game come back alive! This is the best open roaming Jurassic Park game to date and nothing has surpassed this! Thank you so much for this site, I LOVE IT!
How do I get the atx installed?
I have a question, which patch is better? The ATX patch or the trespasser CE? Which one is newer? Thanks!
Hello? Which patch is better, ATX or Trespasser CE? I think that Trespasser CE is newer than ATX if I am not mistaken.
Hi James,
yes it is. Have a look at this thread and join the conversation: http://www.trescomforum.org/viewtopic.php?f=6&t=10674&start=645
Cheers,
Paul
Thanks Paul! Jeez, I can’t believe it has been exactly a year since I have played this game. Time to delve into Jurassic Park Trespasser like never before.
this is a bit overwhelming i’ve never played this game yet….Although I have windows vista and the older ATX seems to say it is not compatible?
oh forgot, also do I need to install that 1.1 patch or any other sort of patch before I put CE/ATX on my game?
Justin: No, the 1.1 patch is not required for either ATX or CE. You can even use all three (all uses their own exe that doesn’t overwrite each other).
I have been trying to get this to work well all day. When I installed the game it launched in like 640 x 480. When I clicked the video options button it would crash. So I installed the Trespasser mod and I could click video. It would go black for about a second then give me a fatal error. Does someone know how to fix this?
Michael: What patch are you trying to install?
Anyone recognize this problem: On my Windows 10 machine, when I run Trespasser CE at 1024×768, medium texture res., in-game “quality” slider at 25%, the first/brachiosaur level is fine, but when the second level loads (plains/raptors attacking triceratops), nothing is skinned correctly and all shapes are a solid red color. I tried every res. setting combo and disabled dither and page manager. Any thoughts? Thank you!
Hi fnj6. Sadly no. I would recommend joining the forum and post about your problem. You will get better help there. 🙂
can someone tell me why i get 30 fps while using the update for 1090 reserlution on a new pc?
Hi satanshund, sorry for late respond.
Which patch are you using? The engine is old and without rewriting it you will still get lower FPS even on modern systems, as the engine was also written for older systems.
Hi, i have this videogame and yesterday i founden in a box with other pc games i have, i install in my pc when i start the game this open the game good but some textures their look in blue colors, and i can change the resolution, i need help to play this game 🙁
Hi Carlos.
I would recommend to register at our forum (link on left or right further up) to get help with that. It is difficult to point out what the issue could be. You could test the “Trespasser CE Patch” patch and see if it helps.
Fun to hear you found it! 😀
Is it possible to get a current guide with a step by step listing of installation for Current PCs.
I believe I have everything installed correctly, have updated with patches, installed some new High res textures and have spent alot of time altering the ini values.
BUT still looks like jank & sometimes I see utubers with a better looking game overall than me.
I can get better resolution and textures, but the ground is superlow res despite my edits, and the hills in the distance have way too high LODs, so can see too much tiling.
Can we get full guide + settings ini?
ie Game + CEpatch + tuxture downloads + latestRecommended downloads + ini file settings for people who have anything between a Geforce 780 – RTX2080
Hello FzN.
There is not recommended .ini settings as you will need to experiment what works for you. One setting that works on one PC will likely not work on all the other. The example ones that comes with the CE downloads are ones that should work for most people.
As for the terrain, there is not way to increase the quality due to how the game handles the terrain.
As for the LODs, not sure you mean the terrain itself or the billboards. The billboards are just flat objects and terrain texture issues is sometimes due to the terrain itself or CE settings.
It is also worth noting that the terrain will very likely look worse and higher resolution you use. The game was not made for resolution beyond 800×600.
I’d recommend joining our forum or Discord to get better help.
So I am playing the game again. But I am wondering about the ATX version. Is there a way to make it use the actual GPU rather than DirectDraw (HAL)? Because when I set the quality and draw distance to maximum, the game becomes impossible to play.
But I notice with the CE version, that the game is using my actual GPU. However, I can’t use cheats like invul or aim.
I’m at a crossroads between ATX and CE.
Hi dreaper. ATX added features into Trespasser by hacking them in, while CE is based on the Tres source code. ATX doesn’t include any support for modern hardware, while CE is based on DX9, which is also why it has a massive performance improvement.
Full draw distance will make most Trespasser levels laggy as ATX has the same performance issues like the retail game.
The AIM cheat would be exclusive to ATX and is not included in CE. Invul was disabled by the devs themselves but I believe it is possible to make it work in CE by adding:
“LogDevInfo=10” below the [Debug] section. You can look at the trespasser.INI example in the CE download doc/trespasser.ini file for reference. 🙂
Is there a way for CE to boot without having the CD or the .iso loaded?
I’m trying to setup a hard drive install, the normal exe from the game works fine, but the CE one doesn’t.
Hi Muffins.
Yes. For a hard drive install you need to move everything from the CD to a folder on your PC and install it from there (if using an ISO, unmount it before installing). The game loads the levels from the “CD”.
An alternative way is to use the Tres demo. Move the data folder from the CD to the demo folder and replace any file it asks. Install CE to the demo as normal and run the Demo EXE once. It will create a tpass.ini file that will make everything portable. Then run CE and it should work as a portable install. 🙂
Hi, Tatu. That works. Thanks! I can live without the aim cheat.
BTW, this games work nicely on Linux with Wine. Better than on Windows. 😉
Hi dreaper. Glad it worked! And it is glad to hear more people are able to play it on Linux even if there isn’t an official or unofficial port. 🙂
Hi Tatu,
There really doesn’t need to be any port. Wine on Linux works perfectly for older games in general. And Trespasser is no exception. In fact, on newer versions of Windows like 10 or 11, I had experienced issues running it; even with compatibility mode. If anything, Wine does a better job at running this game. Or, legacy applications in general.
Beside, I look forward to Valve making gaming on Linux via Proton (Wine fork) even better with their Steam Deck. But for the games I play, I have no issue. The only thing that’s really holding up Linux gaming is anti cheat. But for some anti cheat games, it works on Linux via Proton already. And more will be soon to follow by supporting Proton on Linux.
I am kinda looking forward to MS not having such a stronghold on PC gaming anymore. ;p
Can confirm I just completed a full playthrough on Steam Deck with the CE patch. Played great. Even seemed to adjust resolution between external monitor and Deck. Also the Deck’s touchpad worked great for aiming. Scratch this one off my gaming bucket list!
@no_donatello
Glad to hear it is working, that is cool!
The CE patch cannot be downloaded. Has it been taken down?
Hi Kim. It is still there. This is the old download page, please see the new Patch page on the menu on the left.
