Inside Five CPU Emulators
Building five classic CPU cores in Rust for WebAssembly: 8008, 8080, 8088, Z80, and 6502, with shared state formats, cycle timing, and the edge cases that keep emulation honest.
Video Chips and Serial Streams: Rendering C64 Graphics Over a Modem
How I emulated the VIC-II video chip and forwarded its framebuffer as ANSI escape sequences over a serial connection—turning a 40-year-old graphics architecture into something a BBS terminal can display.
Three Languages, One Weekend (Sort Of)
Building BASIC, Forth, and Scheme interpreters in Rust, running them in browser workers, and what that architecture taught me about language shape.
Deep Dive: The Z-Machine Interpreter
Building a Z-Machine transpiler in Rust—opcode decoding, Z-strings, branch offsets, and the constraints that make Infocom's bytecode tick.
Z-Machine Foundations and Storage Sync
Pushing the Z-Machine interpreter forward with decoder work, text handling, and SAVE/RESTORE—plus content-addressable storage with S3 sync.
Big Repo Restructure and Backend Migration
Splitting the repository into clear domains—cores, languages, assemblers, BIOS—and making future work less of a guessing game.
