From ZX Spectrum to Blazor
summary
A ZX Spectrum emulator implemented in C# and ported to web using .NET 7 AOT runs in the browser and on consoles and phones, reproducing CPU timing, 256×192 screen plus attributes, and 20 ms audio frames. It sends bytes to JavaScript via a shared memory pointer, queues sound on the audio context to avoid glitches, converts Fuse tests to Visual Studio tests, processes 10,000 assembler instructions per frame and demonstrably works at zxbox.com.
