Feature.
2, Viewing a ROM in an emulator, such as OpenEmu, shows a rainbow thumbnail.
Build a ROM and view it in OpenEmu.
The ROM would have the name of the game and the emulator thumbnail would be the titlescreen of the game.
The current behavior will create a lot of games called "game," all with the same thumbnail.
Please tell us about your environment:
Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

(I changed the name of my ROM files manually.)
Set the ROM filename to match the project name is a good idea.
Unfortunately it won't be possible to set the OpenEmu thumbnail, it's my understanding those images come from a private video game artwork library, though you're able to manually set your own.

@chrismaltby: What if we could specify a Background as the "cover art" for the game and when a ROM was built, it would copy that file as a PNG to the rom directory?
That way, when players download the game, they will get everything needed for the variety of emulators out there.
(Just a thought.)
