ProSystem JG
------------
ProSystem JG is an emulator for the Atari 7800.

This is a fork of ProSystem 1.3e with patches from OpenEmu, which contains
patches derived from Wii7800 and js7800.

The code has been significantly altered. It was ported from C++ to C, and
all of the dependencies and Windows-specific code were removed.

This repository lives at https://gitlab.com/jgemu/prosystem

Compiling
---------
Make sure you have The Jolly Good API's header files installed. If you did
not install them, you will be required to include their path in CFLAGS.

Options:
  DISABLE_MODULE - Set to a non-zero value to disable building the module.
  ENABLE_STATIC_JG - Set to a non-zero value to build a static JG archive.

Linux:
  make

macOS:
  make

BSD:
  gmake

Windows (MSYS2):
  make

Cross Compile:
(For example compiling on Linux for MinGW)
  AR=x86_64-w64-mingw32-ar \
  CC=x86_64-w64-mingw32-cc \
  PKG_CONFIG=x86_64-w64-mingw32-pkg-config \
  STRIP=x86_64-w64-mingw32-strip \
  make

The build will be output to "prosystem/". This directory may be used as is
locally by copying it to your local "cores" directory, or may be installed
system-wide using the "install" target specified in the Makefile.

Input Devices
-------------
ProSystem JG uses a game database to determine which input devices must be
plugged in. The following input devices are currently supported:

7800 Joystick
XG-1 Light Gun
