Hey there and thx for your support! ;-)
Dunno as i'm not using geolith myself but these files are standard MAME‑style BIOS zips that are needed for most emulators around.
Thinking about it, i will also add aes.zip which is the BIOS for the home version of the console..
Let us know how it goes ? ;-) if it helps i will duplicate these files for other projects.
