It depends on what MCU is in it, post about it here when you received it. Options are Sean, kevtris, and maybe even the Dumping Union group.
The artwork: I can do simple internal artwork like I did with most handheld games. But if you want photorealistic 'external' artwork, the best option is to do it yourself. It's a lot of work but not a difficult task. Playable game pieces is a thing in progress by crazyc in LUA.
