jg-vecx (Vectrex emulation core for Jolly Good Emulation) Vecx JG is an emulator for the Vectrex. This is a fork of the original, unmodified vecx sources made available by Valavan Manohararajah at http://www.valavan.net/vectrex.html. Many new features have been added since the fork was created. The emulator now contains a new renderer, save states, and support for PSG and DAC based audio. Filenames supported: .vec To run files with other extensions: jollygood -c vecx By default, no controls are mapped. The first time you run a game, press Shift-1 to configure the first controller.
