README.md

Zeta

Zeta consists of:

  • an 8086/80186 emulation core, based on lunatic86,
  • an emulation environment geared specifically towards running ZZT and Super ZZT.

Currently, it has the following front-ends:

  • curses - use ZZT in a terminal (sort of),
  • sdl - primary desktop frontend,
  • web - utilizes the WASM-compiled version of Zeta to allow using Zeta inside a web browser.

Directory structure

  • build/ - contains build output files,
  • src/ - contains the source code to the Zeta emulator, as well as the Curse

Implementing your own front-end

Refer to src/zzt.h. Functions marked USER_FUNCTION are accessible to you to interface with the emulator core, while functions marked IMPLEMENT_FUNCTION should be implemented.

Certain methods can be dummied out:

  • vfs_write - if you don’t need file writing,
  • speaker_on/speaker_off - if you don’t emulate the PC Speaker,
  • vfs_findfirst/vfs_findnext - if you don’t want file lookup to work.

There is, unfortunately, little documentation at this time.
