Vecx JG
-------
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.

This repository lives at https://gitlab.com/jgemu/vecx
