Ace Combat 6 gets an unofficial PC recompilation with major upgrades

Ace Combat 6: Fires of Liberation never made it to PC officially. Nearly two decades after its Xbox 360 debut, though, a new recompilation project is getting surprisingly close to changing that. Called AC6Recomp, the project takes the original Xbox 360 game code and recompiles it for modern x86-64 PCs. That means it isn’t simply running the whole console through an emulator. Much of the game’s original logic runs directly on the PC’s processor, while the graphics side currently relies on technology derived from Xenia. The result already goes well beyond the original console release. You can run Ace Combat 6 at higher resolutions, push gameplay to 60fps, use ultrawide displays and play with keyboard and mouse. It’s still unfinished. But it’s already functional.

From Xbox 360 code to PC

The Xbox 360 used a PowerPC-based processor, which is very different from the x86-64 chips found in most Windows PCs. AC6Recomp converts the game’s executable code so that a modern processor can run it directly. That’s the basic idea, anyway.

The graphics pipeline is more complicated. For now, AC6Recomp still uses a RexGlue and Xenia-based graphics backend, so it hasn’t completely escaped the Xbox 360 emulation world. A more native renderer is being worked on, but that part isn’t finished yet.

You’ll also need your own copy of Ace Combat 6. The project doesn’t include the commercial game files. At the moment, it supports the US release only, so European and Japanese versions won’t work.

Hardware requirements aren’t especially light either. You’ll need Windows 10 or Windows 11, a processor with AVX2 support and a Direct3D 12-capable graphics card. That might sound excessive for a game released in 2007, but recompilation doesn’t automatically make every part of an old console game cheap to run. Graphics translation can still hit the GPU hard, especially when you start increasing resolution and frame rate.

60fps makes a noticeable difference

Ace Combat 6 originally ran its gameplay at 30fps on Xbox 360. AC6Recomp can push that to 60fps, with fixes designed to stop the higher frame rate from changing the game’s flight behaviour. Menus and cutscenes keep their intended timing. Missions get the smoother presentation.

Resolution can also go well beyond the Xbox 360 original. The console game rendered at 1280 × 720, while the recompilation can run at 1440p, 4K and even higher internal resolutions if your hardware can handle it.

Terrain gets an upgrade too. AC6Recomp can use terrain detail stored on the disc at twice the resolution normally used by the original console renderer. It also fixes several visible cracks and seams that could appear across mountainous scenery. Then there’s ultrawide.

Missions can fill wider displays instead of being locked to 16:9, and some in-engine cinematics can stretch across the extra screen space as well. The menus and hangar were built around 16:9, though, so don’t expect every part of the game to suddenly become ultrawide-friendly. Wider cutscenes can also reveal scenery that was never meant to appear inside the original camera frame.

Keyboard and mouse support joins the list

Controller support works as you’d expect, but AC6Recomp also adds keyboard and mouse controls. The default setup takes some cues from Ace Combat 7. Mouse movement can control the aircraft, keys can be remapped and configuration changes don’t require a restart.

For a game that never had an official Windows version, that’s a useful addition. It’s not just about getting the software to launch on a PC. The project is also adjusting how the game feels when you’re actually sitting at one.

Why Ace Combat 6 still stands out

Ace Combat 6: Fires of Liberation launched for Xbox 360 in 2007 and was developed by Project Aces. The story follows Garuda Team during a war between the fictional countries of Emmeria and Estovakia. Its missions were unusually large for the series.

The Dynamic Mission System split battlefields into several operations happening at the same time. You could choose which areas to support while allied aircraft, ground units and naval forces fought elsewhere. Your choices affected how the wider battle developed. The game also brought online co-op and competitive multiplayer to the series.

Unlike several other Ace Combat games, Ace Combat 6 stayed tied to Xbox 360. There was never an official Windows release, which is why this recompilation is interesting from a technical point of view. It isn’t rebuilding the missions or replacing the original game systems. It’s taking the existing game and adapting how it runs.

There’s still work to do

AC6Recomp isn’t finished, and the current builds still have rough edges. Performance can vary. Crashes, audio problems and visual bugs can happen. Some systems still depend heavily on the current graphics backend, which remains one of the bigger areas of development.

A number of fixes are already in place, including changes for rendering glitches, depth-of-field problems, missing missile trails, water-line artefacts and cutscene timing. So this isn’t a polished PC port you install and forget about.

What it is, right now, is a working recompilation of Ace Combat 6 that can already run the game with 60fps gameplay, higher resolutions, ultrawide support and modern PC controls. The next big step is clear: move more of the rendering work away from the existing Xbox 360 graphics layer and closer to a fully native PC implementation.
