Sorry, I completely forgot to mention the demo image I attached contains the 
ROM "Floracy" which is a game that never found a publisher and was later made 
public by the author.

GAMEBOY COLOR HOMEBREW: GAMES, DEMOS AND MORE: What you find here is a large 
section of Gameboy Color homebrew developed over the years, by homebrew I mean 
games/apps and other binaries for use on the Gameboy Color that are actually 
developed from scratch (no hacks).

"Floracy" is a roleplaying game with elements of strategy and action games, in 
which the player breeds plantlike creatures for exciting animated combats. This 
demo was made public by the developer - no publisher was found for the game 
even after several attempts.

I don't think so. You can run with a copyrighted boot ROM if you choose to do 
so, but you can also just set your RAM and CPU registers to mimick what the 
boot ROM does. Even so, there are many gameboy variants (even a super nintendo 
cartridge variant), which all do things slightly differently, so there are few 
official ROMs that depend on any kind of memory or registers being a specific 
way at the start.

Having said all this, there are still murky corners for emulators, and I 
completely understand the question. But my submission is not an open OS or "an 
emulator." In practice its a static machine image built from IncludeOS and my 
embedded GBC emulator, which can only run the embedded freeware ROM which is 
also built into the image. The machine image is hard-wired to play only this 
ROM. I wonder if that might make the whole thing less interesting? This is my 
repository for the emulator: https://github.com/fwsGonzo/gamebro

Just to show what I mean, I have added an example machine image with a free ROM 
(which I have not asked for permission to embed, so this is just to show you 
here). There are also some annoying bugs left in the emulator. If you are 
interested I will create a machine image with a homebrew ROM which I have 
permission to use.

The reason for the large size of the .ISO is because of GRUB. Qemu has an 
if-sentence that exits with an error on Elf64 binaries, which if removed will 
make the image 3MB and would run with multiboot (64-bit) 😊 I don't know how to 
contribute to Qemu to get those lines removed.

Either way, I completely understand if you're not interested. Have a good day.

 Hi,

there are still some open slots left, ... but I'm not sure whether a
Gameboy emulator is really 100% freely redistributable? Don't you also
need some proprietary firmware for such emulators?
