This repository contains a small implementation of the vm BytePysher created by the user Javamannen.
BytePusher is:
- Simple: BytePusher takes minimalism to the extreme. A complete VM including graphics and sound can be written in less than 100 lines of C code.
- Cross-platform: BytePusher's simple structure makes it very easy to write a VM for any OS (or even without an OS). It would also be simple to implement in actual hardware. All programs run cycle-identical and bit-identical across all platforms.
- Persistent: The complete machine state can be saved to a file, and later be reproduced exactly.
- Fixed-size: BytePusher's memory size, screen resolution and keyboard layout are fixed. Fixed-speed: BytePusher is specified as a realtime system with fixed framerate, CPU speed and audio rate. It executes a fixed number of instructions per frame, which means that a BytePusher program can't "hog" the host CPU.
- 100% sandboxed: A BytePusher VM has its own fixed-size "sandbox" memory, which it can never read or write outside of.
You can just checkout the code and build it using cargo.
cargo build --release
and then run it giving it any of the roms in the rom folder.
./target/release/byte_rusther roms/nyan.bp
Should display the animated image below.
