- Clone the repo
- Open the folder of the specific theme variant
- Take the boot_image.bmp out of the folder
- Open up the boot_logo.bmp.gz from the MISC partition in 7-zip
- Place the modified boot_image.bmp into it and replace the original one
- Copy the rest from the theme's folder into the CFW/skins folder in your OS/"ROMS" partition
- Boot into GarlicOS
I've added .psd files (open them up in Adobe Photoshop ~2022) so anyone can make modifications to the icons/boot logo
If you want to have GBA overlays (be it with or without the screen filters), just take the files from "GBA_overlays" and put them into
I:\CFW\retroarch\.retroarch\overlay
After that:
- Enable the original GBA scaling by enabling
Settings > Video > Scaling > Keep Aspect Ratio
- Go to
Settings > On-Screen Display > On-Screen Overlay > Overlay Preset
and choose the overlay you want
