Yet another ZX Spectrum Emulator. Part of a project for an upcoming C++ talk.

• Pre-requisites: CMake, Ninja and a clang compiler newer than 20.
  • On Ubuntu: wget https://apt.llvm.org/llvm.sh; sudo bash llvm.sh 20 all will get you clang and the things it needs.
• LibSDL's development headers and dependencies: sudo apt-get install libsdl2-dev on Ubuntu.
• for the console app libreadline-dev too.
• Build with cmake in your favourite way.

• sudo apt install libc++-20-dev-wasm32 libclang-rt-20-dev-wasm32
• Ensure you have a node and npm installed.
• also a newer WASI and point at it with -DSPECBOLT_WASI_SYSROOT=... and configure with -DSPECBOLT_WASI_SDK
• edit web/.env.local and add VITE_SPECBOLT_WASI_SYSROOT to point at your cmaek build root
• then run npm start from the web directory

Huge thanks to:

• Hana Dusíková for all the clever C++ stuff, and help with modules.
• blargg (aka Shay Green) for the band-limiting code used in the audio.
