The Vectrex draws everything manually by the CPU and one frame to the next ideally the drawing timing does not alter all that much to keep the output as stable as possible.

Emulator-wise please do check the included FAQ which romsets/zips are necessary. Also the data for the ‘KiWi Vectrex Stand’ is included again if you do not have one yet..
