Ah ah !!! I lied again...

... when I said there would not be any update before long : I'm about to release a new minor version soon, that will include two new features :

• Vectrex analog joystick support (through mouse mapping). HyperChase will be playable at last, as well as PatriotsIII in analog mode, for instance... :)
  
  
  Screenshot of the left analog joystick working in the Test Cartridge.
• Automatic building of ROM binaries by compiling your sources through Frank A. Kingswood's AS09 assembler. Now, executing your own programs gets as simple as selecting the source file and clicking the "Build & Run" button!
  
  In combination with this, you can also reload external modifications made to the ROM directly from within ParaJVE, without having to restart it : just select the "Rebuild / Reload ROM" menu item and you're done (no matter what kind of ROM you're running - binary or source).

This latter feature was added in an attempt to make ParaJVE more homebrew developers friendly. This great idea was suggested by Alex of Vectorzoa, who has started an effort to involve more people into vectrex creation... If you're interested, run and check this thread at the rec.games.vectrex newsgroup.
