There's a new version of the Vectrex32 firmware available, version 1.19. This is a really critical upgrade if you have 1.18; it fixes some serious bugs. If you have an earlier version, this is still an important upgrade because it gives you all the features that version 1.18 promised.
If you already own Vectrex 1.10 or newer, you can download the firmware here (https://vectrex32.com/category/downloads/). If you still have version 1.00, please read this (http://forums.vectrex32.com/index.php/topic,28.0.html).
