UpscaLR2 is an injected .dll for Lunatic Rave 2, which fixes fullscreen mode crashes and introduces multiple upscaling methods to choose from.

How To

1. Download fmodex.dll and UpscaLR2.dll from one of releases. If you don't know which one you want, grab latest.
2. Rename fmodex.dll in the root of your Lunatic Rave 2 folder into fmodex_real.dll.
3. If you previously used chainloader to load your mods, remove d3d9.dll from the game folder.
4. Put downloaded files in the root of Lunatic Rave 2 folder.
5. Modify/Create chainload.txt file, adding UpscaLR2.dll to it's first line. It must be first in the load order.
6. See UpscaLR2.ini configuration file, which is generated upon first game launch with the mod, to adjust the settings. Settings apply at game launch.

Note

If you are using graphical mods like LR2ArenaEx or LR2OOL, make sure they are at least dated 12 May 2026. Any future graphical mods will have to implement appropriate DirectX pipeline if they are to work correctly with this project.
