Working CPU
This is outdated, planning on making a better version in the future.
While I never finished this, I have semi working versions of it and am planning on finishing it in the future. this is a fully programable RV32I cpu in the game Scrap Mechanic. this is made entirely with logic gates (and,or,xor,nand,nor,xnor).
There is also going to be a assembler, which would compile the assembly into machine code the computer can understand, then import it into the game. this computer would not be very fast as scrap mechanic is limited to 40 ticks per second, but with mods you can increase that.
so far for the latest version only the drive and ram where complete, with 16kib of storage for the drive. (below is a photo, each dot is one logic gate, and a line is a connection from one to another.)
