re3

That's someone who re-posted their own fork – the original repo <https://github.com/GTAmodding/re3> was taken down in a DMCA action. The only commits they've added are to change the README links to point to their repository.

Isn't this just a fork of the DCMA'ed repository? The links in the readme still point to https://github.com/GTAmodding/re3

This repository is a mirror by a completely unrelated third party. The original repo was https://github.com/GTAmodding/re3.

Also re3 and reVC (Grand Theft Auto III and Grand Theft Auto: Vice City, for PC), though it is down for now, pending the outcome of a court filing... https://github.com/GTAmodding/re3

> If they decompiled the code and just cleaned it up it’s very grey. From the filed complaint, Take-Two quote one of the developers : > GTA 3 and Vice City were originally written in [programming language] C++ . . . The compiled executables that are shipped are in machine code. So the general task is to go from machine code back to C++. . . . To go back to C++ is by no means a simple 1:1 mapping, but over the last 10 or so years decompilers have appeared that help with this process. . . . So what we typically do is work with the output of the decompiler and massage it back into readable C++ And although this probably has no relevance from a legal standpoint, but sounds pretty bad in the context of the complaint, from right at the bottom of https://github.com/GTAmodding/re3/blob/master/CODING_STYLE.m... : > Generally, try to make the code

>If they decompiled the code and just cleaned it up it’s very grey. This is from the CODING STYLE document: "Don't just copy paste code from IDA, make it look nice" https://github.com/GTAmodding/re3/blob/master/CODING_STYLE.m...

If you engage in clean room reverse engineering, probably not. Some have already done this: look at ScummVM and https://github.com/GTAmodding/re3

It is absolutely unbelievable (and unforgivable) that a cash cow such as GTA V has a problem like this present for over 6 years and it turns out to be something so absolutely simple. I do not agree with the sibling comment saying that this problem only looks simple and that we are missing context. This online gamemode alone made $1 billion in 2017 alone. Tweaking two functions to go from a load time of 6 minutes to less than two minutes is something any developer worth their salt should be able to do in a codebase like this equipped with a good profiler. Instead, someone with no source code managed to do this to an obfuscated executable loaded with anti-cheat measures. The fact that this problem is caused by Rockstar's excessive microtransaction policy (the 10MB of JSON causing this bottleneck are all available microtransaction items) is

premake is something like cmake. The sources are at https://github.com/premake/premake-core. The binaries in the repo are from their github actions builds, from whenever I last updated the premake binaries in re3: https://github.com/GTAmodding/re3/pull/945

Not exactly CSV but close. The good thing is now you get to see the...less than optimal code that reads this file: https://github.com/GTAmodding/re3/blob/master/src/vehicles/H...

Apparently, this project requires the game assets to work - so you have to own a (legitimate) PC version of the game. https://github.com/GTAmodding/re3#intro Of course, R*/Take-Two could always make a case.

Check the other branches out! There is one for GTA Liberty City Stories[1], and another one for GTA Vice City[2]. This project enabled people to port GTA to the PS Vita device[3]. This device hasn't seen any games from the franchise, so this is a big thing.

Maybe you'll find the first commit instructive: https://github.com/GTAmodding/re3/tree/600bf0351476a5a21aabb... We were very lucky that we had symbols for global things, which inludes function names and signatures but not return types. We then replaced the first instruction of a function with a jump to our own. global variables can be done with a reference to a raw address. virtual methods are a bit of a challenge but we found way to handle them.

Just saw GTA III re[1], but there are other similar projects that impress me. Prince of Persia[2] is an interesting one as is Starcraft running on arm[3]. And what about you? What is the recompiled software that amazes you the most? [1] https://github.com/GTAmodding/re3 but [2] https://github.com/NagyD/SDLPoP [3] https://pyra-handheld.com/boards/threads/starcraft.73844/
