Version 1.15 has been released. It consists of bug fixes and a very minor new feature. If you already own Vectrex 1.10 or newer, you can download the firmware here (http://vectrex32.com/version-1-15-upgrade/). If you still have version 1.00, please read this (http://forums.vectrex32.com/index.php/topic,28.0.html).
Many thanks to "Astrosynthesist" who found and reported many of the bugs.
