Maximo-GTG

Maximo-GTG

An unofficial native Windows port of Maximo: Ghosts to Glory (PAL, SLES-50703), built on your own PC from your own disc. It uses static recompilation: the game's code is translated to C++ and compiled, with no emulator in between.

This repository contains no game code or data, and no copy of the game. You need your own legally obtained disc. Never share the generated, build or dist folders: they contain the game's code.

Get started

1. Download MaximoLauncher.zip from the Releases page and unzip it to a folder with a short path, such as C:\Games\Maximo. Keep the art folder beside the launcher.
2. Open MaximoLauncher.exe and press Build.
3. Choose your disc image. The launcher checks it against the PAL release, opens it read-only and never changes it.
4. When the build finishes, press Play.

The launcher downloads what it needs: the source code, the libraries, FFmpeg for faster movies, and Git if your PC doesn't have it. If your PC has no C++ compiler, it offers to install Microsoft's free C++ Build Tools, and Windows will ask for your permission. The game itself is never downloaded: it is compiled on your PC from your own disc, which can take a while.

If Windows or your antivirus warns you

The launcher is unsigned and new, so some security tools are cautious about it. Its source is in this repository, and it is built with the C# compiler that ships with Windows.

• SmartScreen may say Windows protected your PC. Choose More info, then Run anyway, if you trust this download.
• Antivirus: a few scanners may flag the launcher through general rules, because it downloads tools and starts a build. Only download it from the Releases page above. If you are unsure, read the source or build it yourself.
• Smart App Control blocks unsigned programs, so it stops the launcher, and probably the game built on your PC. Find it under Windows Security, App & browser control. Read Microsoft's notes before you change it, because it may be hard to turn back on. Your PC is your call: if you would rather keep it on, this port won't run for now.

What you need

• Windows 10 or 11, 64-bit, and a CPU with AVX2
• A graphics card with Vulkan
• A disc image of the PAL release of Maximo: Ghosts to Glory (.iso)
• About 12 GB of free disk space, plus about 8 GB if the C++ Build Tools need installing

To update the game, open Game Files and press Update and rebuild the game.

Build it by hand

You need Git and Visual Studio with Desktop development with C++, including C++ CMake tools for Windows. Visual Studio 2026 is the tested version.

git clone https://github.com/BioRhythmicStudios/Maximo-GTG.git
cd Maximo-GTG
build.cmd "C:\path\to\your\Maximo.iso"

Then open dist\MaximoLauncher.exe. Add --no-ffmpeg to skip FFmpeg; the game then uses its own movie decoder.

How it works

1. tools\kit\maximo_kit.cpp reads the game's executable from your disc and verifies it.
2. PS2Recomp recompiles the executable using the function map in data\funcs.csv.
3. The VU1 microcode is assembled from your executable by data\vu1\recipe.txt and compiled ahead of time.
4. Everything is compiled against the runtime in external\PS2Recomp and the paraLLEl-GS renderer in external\parallel-gs.

In the game

Key	Action
WASD	Left stick
X, Z, C, V	Cross, Square, Circle, Triangle
Q, E, 1, 3	L1, R1, L2, R2
Enter	Start
F12	Screenshot for the launcher's banner
Alt+Enter	Fullscreen or window
Esc	Quit

Controllers work too: plug yours in before pressing Play. The launcher's banner is built from your own disc and your F12 screenshots, on your PC only.

HD textures

The launcher can install Marcus' Ultimate Remaster texture pack from archive.org (9.7 GB), or your own PCSX2-format pack.
