Hello,
now i play Goodboy Galaxy on a few RetroOSes (some like emulatorstation/retroarch combis) and all functioned well. The softpatching function from retroarch is very cool and so rumble works,) and Cartridge saves and states are crossplattform compatible) but i miss Goodboy Galaxy Assets for the emulationstation gamelist.xml. It will be great if it gives some Pictures with the Gameboy Cartridge where peoples can made here own cool Art for the emulationstation oses. Greater it will be cool if you can give an download.
Update: some scraper has medias;)
