.SH DESCRIPTION

\fIv2600\fP is an X/SVGAlib  based emulation of the Atari 2600 video game system. It can
take cartridges as either binary images (2K or 4K), commodore .prg 
format files, Activision Action Pack .bin files and the new .c26 Common 2600
file format files. 

There are two versions, one for X11 and one for SVGAlib. Sound is supported

.SH X RESOURCES
Only applicable to the X11 version.

The user configurable part of the X resources are chiefly the keyboard 
bindings. These are in the *canvas.translations section of the V2600 
app-defaults file and can be set to any key value as defined in 
/usr/include/X11/keysymdef.h although this file may be on a different path on
your system.
.br

The other X resources are in the file to make development changes easier and
should not be altered by the average user.
.br

.SH BUGS and LIMITATIONS
The sound support only plays the pure tone noises. The bank switching is
fairly unstable. Keypad support doesn't work.
