Is there any way to "hack" the game into displaying in 4:3? I got a full retro setup with a CRT and would love to play through Hypnospace on it. It looks so great on it except for the big black bars.

We started a 4:3 mode but never finished it - we didn't really plan for it from the beginning so it'd be a SIGNIFICANT amount of work. That said... I think technically you can still access it via the in-game BIOS, but it'll break stuff, and I'll have to research how to do so.

Hey! I had some extra time this morning, so for you and the other tinkerers out there, I've published a blog post on how to access Hypnospace's hidden and disabled* 4:3 and 16:10 modes:

*for good reason - they're broken and unfinished.

Enjoy!
