Coding 4 Fun: 8-bit game emulation in .NET
summary
A working Atari Lynx emulator written in C# on .NET and using MonoGame runs cross‑platform and models the 6502/65CO2 CPU plus Suzie and Mikey custom chips, memory‑mapped registers and audio/video pipelines, using spans/unsafe for speed and unit plus a 3 million‑cycle CPU functional test that completes in ~1.7s. The repo includes RAM/ROM handling, cartridge support, debug traces, fixes found by tests (a corrupt video bit produced a stray yellow line) and instructions for Visual Studio 2022 or VS Code.
