1. v1.12026-11-08
   • A second control layout, TURN WITH BUTTONS on the options screen: buttons 1 and 2 turn left and right, 3 thrusts, 4 fires, and the stick up is the shield.
   • Coin, game and start on the stick, in either layout: a tap down drops a coin and selects the game, held down it starts it -- the same as button 3, which the game also wants for SELECT.
   • The options screen's CONTROLS page also says what the stick does.
   • 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. v1.02026-11-05
   • First release.
   • A game can be started: after a coin the game wants SELECT to box one of its four games and then START. SELECT was on no button, and the game sat on that screen.
   • Sound through the jack: its two POKEYs emulated, at the level measured against MAME on Gravitar, the same board.
   • The dots show: the stars and the shots.
   • One picture a frame: a second picture inside one frame made still screens blink (found on Gravitar).
   • The cabinet's switches as MAME ships them: three lives. They read four.
   • The picture is MAME's 540 x 400 window, fitted to the screen, at the game's 45 Hz.
   • An options screen at start, after the Vectrex Studio intro: screen vertical or horizontal, refresh, brightness, controls (the buttons can be remapped, and the choice is saved) and calibration.
