I can't seem to select a render mode. It never gives me a chance to enter a number, I see the prompt ">" and then it immediately tells me I gave invalid input.

Adding the dash fixed it for me: cat mario.nes - | nc play-nes.org 4444

However, while i got the game to render, I couldn't get the game to respond to controls after that, so YMMV

Thanks, that did fix it! (Controls working fine too!)
