VecXGL 1.2 (SDL/Win32)
Written by James Higgs 2005/2006/2007.
This is a port of the Vectrex emulator "vecx", by Valavan Manohararajah.
This version uses OpenGL to render the vectors, and SDL to handle the keyboard/controller input, and the audio streaming.
Portions of the source code of are copyright James Higgs 2005/2007.
These portions are:
1. Ay38910 PSG (audio) emulation wave-buffering code.
2. Drawing of vectors using OpenGL.
Comand-line parsing code gratefully borrowed from vecxsdl (Thomas Mathys).
Key mapping and command-line options were also changed to be compatible
with Thomas Mathys' vecxsdl.
Controls:
Arrow keys Vectrex joystick
A S D F Buttons 1 to 4 on the Vectrex controller
Q or Esc Quit
W Toggle audio debug output on/off
P or SPACE Pause
Command-line options:
-h Displays help for VecXGL command-line options.
-b <file> Load BIOS image from file.
If this option is omitted, VecXGL will use
a default BIOS.
-l <#> Set line width. The default line width
is 1. Other values may cause slowdown.
-o <file> Use overlay TGA file. Can be 24 or 32 bit
compressed or uncompressed TGA.
-t <#> Overlay transparency (actually opacity).
Must be in the range [0.0, 1.0].
Default is 0.5.
-x <#> Window width (default is 330 pixel)
-y <#> Window height (default is 410 pixel)
Usually you'll only specify one of the -x/-y parameters.
The other one is then calculated from the given one,
so that the aspect ratio of the window is that of a
vectrex display.
This version only supports overlays which are in 24 or 32 bit
compressed or uncompressed TGA format. The overlay is
converted to a 512x512 texture internally.
