Créé par CaptainYS, il s’agit d’un émulateur pour Windows, MacOs et Linux de Fujitsu FM-Towns et sa déclinaison console Marty. C’est un émulateur du légendaire ordinateur Fujitsu FM TOWNS. Le but est d’imiter le modèle II MX qui était le dernier ordinateur sur lequel l’auteur a (dixit) « prêté allégeance ». L’auteur essaie également de trouver et de documenter autant que possible les fonctionnalités non documentées du système FM TOWNS pendant l’écriture de l’émulateur.
