+This now includes the open source boot ROMs from [https://github.com/LIJI32/SameBoy/](https://github.com/LIJI32/SameBoy/) (for maximum GBC compatibility/authenticity you can still place the Gameboy color bios/bootrom into the Gameboy folder and rename it to boot1.rom)

 Core supports custom palettes (*.gbp) which should be places into Gameboy folder. Some examples are available in palettes folder.
