AthenaOS

Open source reimplementation of the FreyaBIOS/FreyaOS abstraction layer.

Motivation

The main purpose of AthenaOS is achieving interoperability of freely available WonderWitch software with third-party emulators and cartridges. Acquiring a WonderWitch user or development kit in 2024 can cost anywhere between 150 and 500 USD, on top of the cost of the console itself. There is no alternative solution to run most WonderWitch games, other than the second hand market. As such, hundreds of games and applications have no way of being executed in a freely available environment. Like FreeDOS for DOS and WINE for Windows, the goal of AthenaOS is principally to build such a system.

PS. If you just want to play Judgement Silversword, that one is available on Steam.
