No problem to take one or more pictures with the characters, I'll send it to you later today. Just it's a Game Boy DMG with IPS screen, so it's not the real screen of the original Game Boy :) .
For the musics, I made myself my first ones for my game of the Jam, and that requires really a lot of time, so if you need one for a future game, or even to complete this one, don't hesitate to contact me I could make one for you ;) .
I also know GB pic since very little time, but it's true that it's a practical software, even if I make mine with GIMP, with the Game Boy dedicated color palette ;) .
