Okay I was completely not expecting ANYONE to run this on Raspberry Pi It turns out there is no Discord RPC for ARM processors https://www.reddit.com/r/discordapp/comments/blt3c8/rich_presence_and_discord_on_arm_processors/

I’ll try to detect if you’re using ARM processors and disable the Discord I guess…?

Huh I guess the framework doesn’t work for Raspberry Pi at all, sorry =/ So for now I’ll put that in the main readme

I think dealing with several errors like that will fix this issue. It shouldn’t be that hard.

I am also getting the same errors #4943

With some work this project might be considered as a classic game to play on Raspberry Pi?
