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. v1.02026-11-05
   • First release of this port (the earlier 0.1a on this page was Ralf Kornmann's).
   • Sound through the jack: the POKEY, and the board's own circuits -- the crash, the machine gun, the nosedive squeal -- as MAME's model of them, ported line by line. The two levels measured against MAME on its own writes replayed (correlation 0.97).
   • The cabinet's switches are read: English, 3 lives, bonus at 6k/20k/50k. They were not wired at all, and the game read whatever memory held.
   • Coin 2 no longer held: the coin inputs are active low and idled as pressed.
   • The picture is MAME's 520 x 400 window, from Battlezone's measured one, fitted to the screen; what the vector generator draws past it is cut, as MAME does.
   • 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.
   • Fluid at 60 Hz: the cartridge runs at 300 MHz (at 150 the emulation and the drawing filled the whole frame, 56-57 fps), and one picture a frame -- the board runs at 61.5 Hz, so now and then two pictures fell into one frame, doubling the strokes and making the picture beat.
