ARMORED CORE 4 PC port 0.5.0

A native Windows version of ARMORED CORE 4 (PS3, USA, BLUS30027). The game's own PS3 code is translated into a real Windows program, built on your PC from your own copy of the game. This project contains no game data, no game code and no keys, and it decrypts nothing.

Install

What you need

• Windows 10 (1903 or later) or Windows 11, 64-bit, a CPU from Intel Haswell or AMD Ryzen onward (AVX2, the launcher checks) and a Direct3D 11 graphics card.
• Your own copy of ARMORED CORE 4 (US disc, BLUS30027, disc version 01.01). You need the disc's files, meaning the folder that contains 'PS3_GAME'.
• RPCS3, used once during setup to decrypt a few of your game files.
• The PS3 system software 4.93 file 'PS3UPDAT.PUP' from Sony's PS3 system software page.
• About 4 GB of free disk space and an internet connection.

Steps

1. Download AC4-Port-0.5.0.zip below.
2. Right click the zip, choose Extract All..., and pick a folder with enough space, for example 'C:\Games\AC4-Port'.
3. Open that folder and start 'AC4-Launcher.exe'. If Windows says "Windows protected your PC" (the launcher is not code-signed), click More info, then Run anyway.
4. Under Game folder, choose the folder that contains 'PS3_GAME'.
5. Click Prepare files and choose your 'rpcs3.exe' and 'PS3UPDAT.PUP'. The launcher uses your RPCS3 to decrypt the files the port needs. When RPCS3 asks "Install firmware?", click Yes. This takes under a minute and doesn't change your RPCS3.
6. Click Set up. It downloads the build tools and builds the game. This takes a few minutes and is only needed once.
7. Choose whether you want a desktop shortcut and a Start menu entry.
8. Click PLAY.

From now on, the shortcut opens the launcher; click PLAY.

Note

Already decrypted the files yourself? Skip step 5 and choose their folder under Decrypted files instead. More... > Which files does the port need? lists them.

Update

Unzip the new release into a new folder or over the old one, start its launcher and click Set up. It finds your earlier install and rebuilds only what changed; your settings and saves stay. If your game data is in the old release's folder, keep that folder, or choose Move it beside this launcher.
