Hey, I'm fascinated about this expansion of XO-Chip! We'd like to discuss about this more, would you interested join into the Emulation Development discord server? There's might be a lot to be talked there https://discord.gg/dkmJAes ;)
Hey Kouzeru, thanks for the invite!
It's not really an extension to XO-chip, it's already in the spec, it's just not been implemented by interpreters :) The only thing that isn't defined is the colour palette. I've been thinking about drafting a separate proposal for the palette, but I have yet to finish that.
I've joined the Discord server, but I don't normally use Discord much so I need a few pointers ;) I'm Timendus on Discord too. Hit me up!
