Say Hello to Moira
Moira is a Motorola 68000, 68010, 680EC20, and 68020 emulator with high emulation accuracy, both functionally and temporally. It was designed for Amiga emulation which does not only require exact cycle counts, but memory accesses being performed at the proper DMA cycles.
Moira can be compiled on all major platforms (Linux, macOS, Windows) with a standard C++20 complient compiler such as GCC, Clang, or MSVC. The source code is compatible with WebAssembly, too, which makes Moira a first-class candidate for being used in web-based applications.
