About
Tomb Raider: Chronicles is a 2000 action-adventure game developed by Core Design and published by Eidos Interactive, the fifth entry in the Tomb Raider series, in which three friends recall archaeologist Lara Croft's earlier adventures after her presumed death, across linear levels of puzzles, combat, and some stealth. TOMB5 is an in-progress decompilation of Tomb Raider: Chronicles, reconstructed from the final PlayStation and PC versions using debugging symbols and reverse-engineering tools since the original source code is reportedly lost. Current work focuses on decompiling code through the title screen sequence before moving on to in-game code.
How it differs from the original
The decompiled code isn't expected to be a 1:1 match with the lost original source, though it aims to be functionally identical, and it only targets the final NTSC PlayStation and PC versions rather than other localized releases.
Getting started
Requires your own copy of the original Tomb Raider: Chronicles PlayStation disc — after building the project, copy the disc's files into the same folder as the resulting executable to run it.
History
The decompilation effort began on June 21, 2017, and the project's own README warns it may be abandoned at any time.
