1. v1.12026-11-08
   • The romset can live in any folder of the card. The game looks in .roms/, then roms/, then searches the whole card, and remembers where it found it (.conf/<romset>.loc), so the next start goes straight there; if it is moved, it is searched for again.
   • Settings go in .conf/ and romsets in .roms/: the UVMC2's menu hides folders whose name starts with a dot, so the card shows only the games. A card set up before keeps everything: the old config/ and roms/ are still read, and nothing is written to them any more.
   • Without the romset on the card the screen says ROM FILE NOT FOUND and the name of the zip it wants.
2. v1.02026-11-06
   • First release.
   • Sound through the jack: the board's two POKEYs emulated, one on each side. The options screen can send them through the Vectrex's own chip instead.
   • The arcade's upright screen, as MAME shows it (checked frame by frame against MAME), fitted to the tube by the console's calibration. It used to be framed on what the game drew: scaled and off to the left.
   • An options screen at start, after the Vectrex Studio intro: sound, refresh, brightness, controls and calibration.
   • On the web, the same two POKEYs in stereo.
