ZXGame

A portable front-end library for ZX Spectrum game ports written in C.

• src/ZXSpectrum: a virtual Spectrum (screen conversion, keyboard, Kempston, 128K paging, AY, timing, and macros and helpers that emulate Z80 instructions for code translated from a disassembly). It has no Z80 CPU emulation.
• include/ZXGame/Game.h: zxgame_ops_t, the vtable a game supplies.
• hosts/: front-ends for SDL3, headless, macOS, Windows and RISC OS. See hosts/README.md for the state of each.

Used by The Great Escape in C and Chase H.Q. in C.
