But what about the rest of us, who can only play on emulators or Famicom?

It should work on Famicom (with an adapter), preferably the AV because player 2 will be at a disadvantage without a select button. PAL should sorta work, but timing will be off and the music will sound bad as the cart is designed for NTSC. Aside from that, there's always the soundtrack to listen to!

We recently released a new NES game called Star Versus. It's a hybrid fighter / shooter with a complex control scheme, sorta like Street Fighter with spaceships, and available only on physical cartridge. You can check out the trailer here - https://www.youtube.com/watch?v=U63ImXUtIvE

Today, Knife City put up the soundtrack on his bandcamp, you can get it for whatever price you want! Check it out - http://knifecity.bandcamp.com/album/star-versus-ost
