Meka – multi-machine emulator

Last Updated on July 11, 2021

MEKA is a multi machine emulator, originally started as a Sega Master System emulator, and generally very oriented toward Z80-based Sega 8-bit systems.

Original VDP (Video Display Processor) functionalities have been implemented as accurately as possible, including some obscure features, so most games should be displayed accurately.

MEKA includes a dedicated graphical user interface (GUI).

The origin of the name MEKA comes from the dragon Meka (or Mecha) in the Master System game Wonder Boy III: The Dragon’s Trap.
