mgshdfix Config Tool and Settings Explained

Installing MGSHDFix is the easy part. The interesting part is the Config Tool, the small program that lives in your game folder and controls everything the fix can do. Custom resolutions, ultrawide support, anti-aliasing, gamma, controller behaviour, launcher skips, even a few hidden extras Konami and Bluepoint never shipped: it all flows through this one tool. If you open it for the first time and feel slightly overwhelmed by the number of checkboxes, this guide is for you. We will explain where the tool lives, how its settings are saved, and what the important options actually do, so you can set up each game the way you like it and stop guessing.

Finding and running the Config Tool

After you extract MGSHDFix into a game folder, look inside that folder for the /plugins folder. The MGSHDFix Config Tool sits in there. Run it before you play for the first time, because on a first install the tool generates the settings file that the fix reads at game launch. No settings file, no applied settings; that is the single most common reason players think the fix is ignoring them.

The workflow is simple:

Open the Config Tool for the game you want to adjust
Change the settings you care about
Save, close the tool, and launch the game through Steam
To change something later, close the game, reopen the tool, adjust, and relaunch

Each game has its own copy of the fix and its own settings, so the MGS2 tool and the MGS3 tool are separate. That is a feature, not a nuisance: you can run MGS3 with the retro camera behaviour and MGS2 with every experimental extra switched on, and neither setup disturbs the other. A good habit is to change one or two things at a time, test them in game, and then continue. If something looks wrong, you will know exactly which toggle to blame.

Display and resolution settings

This is the section most people install the fix for. Here you set the custom resolution the game renders at, which is how ultrawide and other non standard displays get proper support. Remember that the game’s own launcher must have Internal Resolution and Internal Upscaling set to Default / Original, because MGSHDFix handles resolution entirely. Alongside resolution you will find the display mode options, including borderless and windowed modes, and the mouse cursor toggle, which lets you hide the cursor while you play so it does not drift across cutscenes.

MGS2 and MGS3 also get the experimental 16:9 HUD option, which resizes the HUD and movies for widescreen play. Experimental is the operative word. It makes a real difference on wide monitors, but if your HUD ever looks stretched or oddly placed, this option is the first suspect, and turning it off returns the interface to its default presentation.

Graphics settings

Several options change how the games actually look:

SMAA anti-aliasing (MGS2 and MGS3) smooths jagged edges without the heavy cost of traditional supersampling. For most players this is an easy yes.
Anisotropic filtering (MGS2 and MGS3) sharpens textures viewed at an angle, like floors and runways stretching away from the camera. Higher values give a cleaner image.
Gamma correction applies to all supported games and is one of the fix’s most loved features. It makes colours more vibrant and blacks deeper, closer to how these games looked on a CRT television.
Disable bilinear filtering goes the other direction on purpose. Turning texture filtering off gives the games a crisp pixel art, retro appearance, which MSX and PS2 purists may genuinely prefer.
Increased texture size limits (MG1, MG2 and MGS3) and the option to force highest polygon models during gameplay and cutscenes both push visual quality upward where the original ports held back.

One honest warning from the project’s own notes: at very high resolutions, some visual glitches and post-processing oddities are known issues. If you see strange effects after pushing resolution hard, step it down a notch before you start disabling everything else.

Gameplay and convenience settings

This is where MGSHDFix quietly becomes a quality of life mod. You can skip the launcher, which gets you into the game faster, and skip the intro logos in MGS2 and MGS3. You can disable the automatic pause when you alt-tab, which is a blessing if you check messages or a guide on a second monitor. There is an option to restore the original PS2 memory card strings and messages, a small nostalgia hit for anyone who played these games on the original hardware. Cutscene caption scale and opacity can be adjusted to taste, and the option to disable the 2011 HD Collection camera changes lets purists return MGS2 and MGS3 to their original camera behaviour.

Controller settings live in this neighbourhood too: DualShock 2 and 3 support with pressure sensitive analog face buttons, the option to swap X and O between OK and Cancel in menus, and support for custom PS2 controller glyphs that does not overwrite existing textures. There is also an option to keep aiming your gun after firing it in first person or lock-on, a small change that veteran players tend to appreciate immediately.

Speedrunning and internal settings

Two features deserve a mention even if you never use them. The speedrunner options include an in-game timer and statistics overlay, plus the option to disable Steam achievement unlocking, which competitive runners use to keep their runs clean. And on the Config Tool’s Internal tab, there is an option to start MGS2 and MGS3 in their developer menu level select screens. That is a genuine piece of game history sitting in a checkbox: a debug style entry point the developers used, now available to anyone curious enough to explore it. Handle it like a bonus feature, fun to explore, not part of a normal playthrough.

The toggleable wireframe modes also live on the experimental side of the tool. They are not settings you play with; they are settings you peek behind the curtain with, showing the raw geometry of scenes you know by heart. Features like these are why fans love this project. It treats players like adults and lets them poke at everything.

A sensible order for your first setup

If the sheer number of options is putting you off, work through the tool in this order and stop whenever you are happy. First, set your resolution and display mode, because those define the whole presentation. Second, turn on gamma correction, because it improves every game in one click. Third, if your game supports it, enable SMAA and raise anisotropic filtering. Fourth, add the conveniences you will feel every session: logo skips, launcher skips, and the alt-tab behaviour you prefer. Everything after that, the cameras, the wireframe modes, the developer menu, the retro filtering, is exploration. The tool rewards a layered approach: a solid base setup first, curiosities later, one experiment at a time so you always know what changed.

Conclusion

The MGSHDFix Config Tool, found in the /plugins folder of each game, is where the fix becomes yours. Run it once to generate your settings file, then work through the display, graphics, and convenience sections at your own pace, changing a couple of options at a time. Prioritise resolution and display mode first, add SMAA and gamma correction for an easy visual upgrade, then explore the deeper options, from pressure sensitive buttons to developer menus, whenever curiosity strikes. Set up thoughtfully, each game in the Master Collection ends up configured exactly the way you want it.
