Nintendo logo:
The Nintendo logo is a registered trademark of Nintendo Co., Ltd.

A Game Boy (DMG-01) ROM must include the graphics for the logo in order for the Game Boy to execute the program. There have been a number of unlicensed games for the Game Boy on the market, all containing this Nintendo trademark, but Nintendo has never taken legal action against them. This may be thought as precedent for Nintendo not enforcing its trademark in Game Boy software.

Further, Sega had a very similar system in the Mega Drive, which also required the inclusion of Sega trademarks in games to execute on the system. However, unlike Nintendo, Sega decided to go after unlicensed publishers. Sega filed a law suit against Accolade in 1991, which Sega eventually lost. This set the legal precedent that "copyrights do not extend to non-expressive content in software if it is required by another system to be present in order for that system to run the software". This was in the US, of course, and is not directly valid in Finland. (See e.g. https://en.wikipedia.org/wiki/Sega_v._Accolade ).

In conclusion, I consider using the bytes representing the Nintendo logo in the header of the ROM to be fair use.

The scrolling of the Nintendo logo during the start up of a Game Boy is done from the boot ROM of the system. I've left this part out of the video, although it is a very iconic feature of the Game Boy.

(If you cannot allow the inclusion of the logo even in the ROM, then please contact me. It is possible to prepare a ROM image without the logo, which can still be executed in emulators and third party "Game Boy compatible" systems, but just not on the original Game Boy.)
