To reduce download size, the base theme includes only essential assets.
Optional addons (4K images, videos, console arts, wallpapers, etc.) can be installed separately.
/themes/ckau-book → Main theme directory
/themes/ckau-book-addons → Addons directory (not overwritten by ES updates)
You can install and update addons automatically using the included script:
tools/install-addons-batocera.sh
This script provides an interactive menu for managing all official addons (4K images, videos, console arts, wallpapers, etc.).
It also supports command-line usage and will automatically keep track of installed versions.
📘 For full usage instructions, see
tools/install-addons-instructions.md
Currently there is no automatic installer for RetroBat. Batocera users can choose to use manual mode too.
In this case, addons must be downloaded manually from the corresponding GitHub repositories:
| Addon | Description |
|---|---|
| COLORFUL 4K Images | High-detailed, beautiful 3840x2160 system images |
| COLORFUL Video Pack | Gameplay videos for each system |
| CINEMATIC Video Pack | Full-screen cinematic system view |
| CONSOLES / WALLPAPERS | Console or wallpaper-based layouts |
In addition to covering all systems in the latest version of Batocera/Retrobat, the theme also supports extra systems not officially included (e.g., Aleck64, Amiga 600/4000, Casio Loopy, Dragon 32, etc.).
