This is an open source implementation of the classic Tomb Raider I game. It was made by reverse engineering the TombATI / GLRage variant of the original game and replacing proprietary audio/video libraries with open source variants.
See the Tomb Raider Forums topic.
This project was inspired by Arsunt's TR2Main project and the legacy name, "Tomb1Main", reflects that.

Download the latest Tomb1Main release from the GitHub releases.
https://github.com/rr-/Tomb1Main/releases -
Unpack the contents to your game directory.
Make sure you choose to overwrite existing directories and files (Tomb1Main_config.json5can remain). -
(Steam users / music) The Steam version of the game does not ship with the music assets due to the publishers' negligence. If you have previously installed TombATI, you don't need to do anything. Otherwise you can download the music files from the link below.
https://mega.nz/file/f9llhQAY#y0RqaMhR4ghtQ-1IFAGbHep_FCmkV8Q66bzdMWVqtuY
These assets are not a part of this project. The legality of these is disputable. The most legal way to get the music on PC is to rip the assets yourself from a physical PlayStation disk. TombATI ships with this music by default, which this project chooses not to do. -
Launch
Tomb1Main.exe.
-
(Steam users / Unfinished Business) The Unfinished Business expansion pack is freeware, however, the Steam version of the game does not ship with it and you'll need to install it separately. If you have previously installed TombATI, you don't need to do anything. Otherwise you can download the expansion pack from the link below.

Launch the game with
-goldcommand line switch. A more detailed instruction:-
Create a shortcut to
Tomb1Main.exe. -
Select the newly created shortcut, go to File Properties.
-
At the end of the "target" field, append
-goldso it looks something like this:
(...)\Tomb1Main.exe -gold -
Launch the shortcut.

If you install everything correctly, your game directory should look more or less like this (click to expand):

Is the game fully playable from beginning to the end?
Yes. If you encounter a bug, please file a ticket.
-
Can we get HD textures? Reflections? Other graphical updates?
Eventually, probably yes. Please see the road map to have a general idea what is currently being worked on.
-
Can we get braid in every level? Skyboxes? Flyby cameras? New animations? etc.
Not sure at this moment; this requires meddling with the original game level files. It's one thing fixing a faulty trigger bit in The Great Pyramid for the final secret, and another to insert a completely new animation, a textured mesh or a sound file and pretend it's always been a part of the original game. So far we haven't found a good way that'll keep the code maintainable.
-
Can I play this on Mac, Linux, Android...?
No promises here, but the game is now playable with wine (including sound and music) and there is planned work towards reducing the amount of Windows-only code.
