WidescreenFix 1.0.0

Full 32:9 / super-ultrawide support for Double Dragon Gaiden: Rise of the Dragons.

Install

1. Download DoubleDragonGaiden-ROTD-WidescreenFix-1.0.0.zip.
2. Extract it into the game folder (the one with DoubleDragonGaiden_ROTD.exe; in Steam: right-click the game → Manage → Browse local files).
3. Launch the game.

The zip includes BepInEx 5.4.23.5 (x64). Already have BepInEx 5? Just copy WidescreenFix.dll into BepInEx/plugins/.

What it does

• The world is rendered at the full width of the screen: no black bars at the sides
• No invisible walls at the old 16:9 edges: walk to the edge of your screen; enemies at the sides are not despawned
• Main menu, mission select, game over and versus menu backgrounds fill the whole screen
• UI keeps its 16:9 size and layout, with no jumping loading screens
• Cutscene letterbox bars cover the full width

Tested at 5120x1440. Every feature can be switched off in BepInEx/config/com.yourname.widescreenfix.cfg (see the README).

Linux / Steam Deck (Proton) (untested)

Use the same zip, then in Steam → game Properties → Launch Options enter:

WINEDLLOVERRIDES="winhttp=n,b" %command%

Without it, Proton ignores the bundled winhttp.dll and BepInEx never loads. Not tested yet with this game; feedback welcome.
