This is an attempt to override Forge's early loading screen.

Usage may be unstable, and the game can crash unexpectically

Forge does not support custom early window (NeoForge does), so I tried to use an ugly "hack" to override it.

Unfortunately, the override is applied quite late, which may result in the original red early loading (or a white screen) to "flash" on the very game start. I can't do anything about that.

However, the red color of the original loading can be changed using darkMojangStudiosBackground:true in options.txt.

Installation

In contrast to NeoForge, this requires the default value in fml.toml:
earlyWindowProvider = "fmlearlywindow"
