e8Bit Emulator

[mint perch]

A lightweight 8-bit VM emulator written in Rust. It simulates a basic CPU with registers, memory, and a custom instruction set. I'm making this project do develop my Rust skills and understand how some things work.

this is very cool

Hey! This is extremely cool. On the topic of 8-bit CPUs, I highly recommend you play through Turing Complete. It teaches you the very base of everything from a simple XOR to a full-fledged LEG Computer, with 4 byte instructions. You even make the assembly code yourself!

Thanks for the recommendations, I'm very interested in the low level of the computers, thanks!

Of course! It is a fairly easy game, but if you ever have trouble, come by on their discord server, they will answer within minutes!
