Virtual Atari 7800
Dan Boris

v7800 is an Atari 7800 video game emulator for MSDOS. I originally wrote this code to be part of the MESS multi-system emulator but also decided to release it as a standalone emulator while the next version of MESS is still in development. This emulator is a pretty quick and dirty hack of my code so it's not perfect and a little slow, but it's playable.

Introduction
        
        v7800 is an Atari 7800 video game emulator for MSDOS. I originally
   wrote this code to be part of the MESS multi-system emulator but also decided
   to release it as a standalone emulator while the next version of MESS is still
   in development. This emulator is a pretty quick and dirty hack of my code so
   it's not perfect and a little slow, but it's playable.

The current version of v7800 can be found at:

---------------------------------------------------------------------------

v7800 was written using DJGPP a free 32bit C/C++ development system:

        http://www.delorie.com/djgpp/ 

v7800 uses Allegro, an excellent game programming library for djgpp by Shawn
Hargreaves:

TIA sound emulation was done with TIA Sound V1.0 by Ron Fries.

v7800 uses the SEAL sound library. SEAL Synthetic Audio Library API

----------------------------------------------------------------------------

Setup:

        Before you can run v7800 you need a copy of the 7800 BIOS ROM. For
copyright reasons I am not including this ROM image in this archive, but
it can be found at:

        http://www.emuviews.com/

Once you get the image rename it to 7800.rom and put it in the same directory
as the emulator.

If you are running under plain MSDOS you must copy the file CWSDPMI.EXE to
your root directory.

You will also need cartridge images, but again for copyright reasons I cannot
provide these. PLEASE DO NOT E-mail me asking for ROM images! All messages
asking for ROM images will be promptly deleted. The carts must have a 128
byte header to work properly with v7800, see details on this below. ROMS with
the extension .A78 will probably already have the header attached.

The following games run almost perfectly:
Pole Position II, Ms Pac Man, Galaga, Dig Dug.

-----------------------------------------------------------------------------

Basic Usage:

To start v7800 simply type v7800 followed by the name of the ROM file you want
to load. For example to load a file called poleii.a78 you would type:

V7800 POLEII.A78
