Changelog

1. v1.22026-11-08
   • 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. v1.12026-11-07
   • Phasers fire under impulse power. Impulse and phasers (buttons 2 and 1) were the coin combination, which blocked every button while held: thrusting and shooting at once was impossible, and each shot dropped a coin. Reported by a player.
   • No button combinations any more: all four buttons always reach the game. The board has no free-play switch, so pulling the stick fully down inserts a coin and starts (free play).
   • The controls screen names the buttons: FIRE, IMPULSE, TORPEDO, WARP.
3. v1.02026-11-05
   • First release.
   • The Universal Sound Board emulated whole -- its 8035 and the tone and noise generators it drives -- run on the Z80's own time: the attract music matches MAME's within 5%.
   • The speech board emulated whole (its 8035 and SP0250), with the game's speech ROMs.
   • The cabinet's four buttons on the pad's four; a coin and START are two-button combinations the game never asks for.
   • Runs at 40 Hz, at 300 MHz.
   • Every vector visible: a coloured one is as bright as a white one, and the board's three colour levels are the Vectrex BIOS's own intensity steps. The dimmest were barely visible before.
   • The cabinet's switches as MAME has them (they read 0: cocktail cabinet and odd lives), and the Z80 at the board's own 3.87 MHz instead of 3.0.
   • The picture fitted to the screen.
   • 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.
