AnyAspectRatio Decky Plugin 1.1.0

AnyAspectRatio for Decky

Play your games at fullsceen 16:10 on Steam Deck and SteamOS.

Install

Requires a Steam Deck (or SteamOS) with Decky Loader.

1. Download AnyAspectRatio-1.1.0.zip from the latest release.
2. Put the zip on the Deck (for example in Downloads).
3. In Game Mode, open Decky (... button), then Settings → General and turn on Developer mode.
4. Open Settings → Developer → Install Plugin from ZIP, pick the zip, and confirm.

Tabs

• Mods: shows who made the mods. Two buttons:
  • Import repository zip...: use all of this repository's mods offline. On a PC or the Deck's browser, open this repository on GitHub, choose Code → Download ZIP, and save it in the Deck's Downloads folder. Then pick it here.
  • Delete all local files and caches: frees the space used by imported or downloaded files. Your settings and already-applied mods are kept.
• Settings: where mods come from, an optional folder of your own mod zips, and Update to fetch the newest mod list.

Special thanks to Lyall

A large part of the game list comes from the work of Lyall, whose open aspect-ratio and UI fixes are mirrored in external/Lyall (full list with Steam IDs and release dates in its README) and installed unchanged by this plugin. If these fixes make your games better, please support him:

License

MIT. Third-party notices are included in the zip.

Visions of Mana v1.0.0

Initial release: custom resolution and FOV support. Default resolution: 1280x800. SteamOS / Proton launch option: WINEDLLOVERRIDES="dxgi=n,b" %command%

Dynasty Warriors 3: Remastered v1.0.0

Custom borderless-window resolutions, including narrow aspect ratios such as 1:1, 3:2, and 4:3.

Final Fantasy XIII v1.0.0

FINAL-FANTASY-XIII-Any-Aspect-Ratio

Why?

• The existing Final Fantasy XIII Ultrawide Fix crops the image to fill handheld screens. I made this patch to preserve the full image at narrower custom resolutions below 21:9, such as the Steam Deck's 16:10 display.

1. Install vibration fix, +7fps: https://github.com/rebtd7/FF13Fix

2. Install
   Extract the contents of Final-Fantasy-XIII-v1.0.0.zip into the game's bin folder:

steamapps\common\FINAL FANTASY XIII\white_data\prog\win\bin

The folder should contain FF13_ARFix.asi, FF13_ARFix.ini, and dinput8.dll. Keep them beside the game's ffxiii2img.exe. The README and license file are documentation; they do not need to stay in the game folder.

3. For SteamOS / Winlator (Wine Users)

For SteamOS / Proton, open the game's Properties, then General > Launch Options, and use:

WINEDLLOVERRIDES="d3d9,dinput8=n,b" %command%

This enables both the game's d3d9 proxy and the mod's dinput8 ASI Loader. It can be used alongside other mods such as FF13Fix; keep both DLL names in the same WINEDLLOVERRIDES value rather than adding a second variable. On Windows, no launch option is needed.

4. Configure the Aspect Ratio

The included FF13_ARFix.ini is preconfigured for the Steam Deck's 1280x800 display:

[Resolution]
ReplaceWidth=1280
ReplaceHeight=720
TargetWidth=1280
TargetHeight=800

Nova 4:3:
In launcher, select Window mode with 1920x1080, set Stretch mode

[Resolution]
ReplaceWidth=1920
ReplaceHeight=1080
TargetWidth=1280
TargetHeight=960

To use another display, edit only TargetWidth and TargetHeight to that display's resolution. For example, use 1280 and 800 for 16:10, or 1920 and 1080 for 16:9. Keep ReplaceWidth=1280 and ReplaceHeight=720 match your launcher setting: these are the original values the patch searches for in the game, not your display resolution. (Some SteamOS, like DroidDeck, only work at 1080p.)

5. Known Issues

• The GUI may be misaligned at custom aspect ratios.
• At very narrow aspect ratios such as 4:3, subtitles may be obscured by the video.

The bundled dinput8.dll is the 32-bit Ultimate ASI Loader. Its MIT license is included in Final-Fantasy-XIII-v1.0.0.zip and in the repository root.
