I'm actually still trying to figure out exactly what I'm looking for.
Think of it this way - I've replicated the whole SFII arcade experience and themed it, kind of like a parody. So, ideally I swap Capcom's music for original (or remixed?) audio and the length and arc of the songs matches. However, the setting is the late 1800's (but the style is 16 bit / arcade) so there's LOTS of room for creativity.
If I get multiple contributors or one collaborator, I'll be happy!
The real beauty of this project is the physical cabinet. If it helps recruit or inspire, I can ask my team if it's wise for me to spill the details online. There's a really clever twist.
I'll talk to my team and let you know. In the meantime, please keep the feedback and suggestions coming!
