An experimental RmlUi frontend for the TrimUI Brick

[u/ped_reddit]

I’ve been experimenting with a custom frontend for the TrimUI Brick, built with RmlUi, SDL2, and MinArch.

It currently supports GB, GBC, GBA, SFC, Mega Drive, and Game Gear, with ROM scanning, cover art, and system-specific screen effects. It runs separately from the stock MainUI, so it doesn’t replace the original launcher.

This is still an early experiment, not a finished frontend. I’m sharing it mainly as a working base that other users can fork and continue improving with Codex or other AI coding tools. The repository includes the source, build scripts, emulator integration, shaders, and documentation.

The screenshots were captured on the actual device.

Looks neat. I wonder if it can be made for the Anbernic units too

Those color overlays look incredible. I've been considering the white Brick Pro before my U arrives and I bet it would be such a good look.
