These are all sources and ressources for "Vectorblade" a Vectrex game and port of the good old "Deluxe Galaga" / "Warblade".
To build it you need Vide, since the game consists of four seperated banks and address information "over" banks is injected into each bank-binary by Vide in an additional "linker" stage.
Vide is a VECTREX INTEGRATED DEVELOPMENT ENVIRONMENT (http://vide.malban.de), it is free and can be downloaded for several OS at the given homepage.
