leverage the multi-platform nature of SDL to provide first-class support for
the major plaforms supported by SDL, which includes Mac OSX, Windows and Linux.
I'm not a huge fan of OSX, but I keep a MacBook Pro nearby for work, so the
first version to be release is this OSX build. I'll try to have builds for
other platforms available in a few weeks.
Some notes:
# USAGE NOTES
You need to provide the ROM file and disk images and a config file. I'd
recommend you just drop it in your current GSport or KEGS folder and run it
from there.

Overview & Purpose
This project is an attempt to build a better Apple IIgs emulator by modernizing the KEGS/GSport emulator family and extending it into a platform.
This project is an attempt to build a better Apple IIgs emulator by modernizing the KEGS/GSport emulator family and extending it into a platform for gamers, enthusiasts and developers.
The first steps were a release of a new SDL2 driver. SDL or "Simple DirectMedia Layer" enables the writing of one cross-platform driver to handle input and output (video, mouse, keyboard, audio, joystick). This helps the goal of providing first-class support for all of the major platforms supported by SDL, including Mac OSX, Windows and Linux.
Part of this effort has also led to the development of an automated build and packaging pipeline using Gitlab CI. This helps our team of one continue to develop on primarily a single platform, while still ensuring that it works across many operating systems
Currently, the main supported platforms are Linux, OSX and *Windows.

Getting started

1. Download the emulator package from https://apple2.gs/plus and put it in a folder
2. Download the Apple IIgs Firmware ROMs, for either a ROM01 or ROM03 machine.
(If you have a real IIgs, there are ways to save it from your machine too.)

Mac/Ubuntu: ./gsplus
If the config file cant be found, it will try to create a config.txt file for you, with all of the defaults.
1. Note: You can also specify a config file. This is very useful as you can have specific disks/setting pre-set in a config file and launch directly into your favorite game with that config. They can be named anything you want, though the officially recognized extensions are .txt and .gsp.
Examples:
Windows: gsplus32.exe -config arkanoid.gsp
Mac/Ubuntu: ./gsplus -config choplifter_config.txt

Other Input/Output
1. Mouse and keyboard should automatically work
2. Joystick with SDL2 driver is known to be working. It simply uses the “first” joystick and the first analog pad on that stick plus the first two buttons. The axes and buttons are not yet configurable. Better info forthcoming.
3. There are drivers for serial controller, ImageWriter (II?) printer, and networking. I may have broken some of this functionality to get builds working. Im not currently familiar with the state of these drivers or their usage. More info will be added as I take time to research more of the modules.
4. You can also drag-and-drop disk images onto the emulator window and it will try to automount the disk! (SDL versions)

Configuration Menu
Configuration options are loaded from, and saved to, a configuration text file. The default configuration file is config.txt. If you are just starting out, its recommended to use the configuration menu versus editing the file yourself.
Enter the configuration menu at any time while running GSplus by hitting <F4>.

Most important options are:
Disk Configuration menu - options to “mount” and “eject” disks images
ROM File Selection menu - if you dont have it correctly pointing to a valid ROM 1 or ROM 3 image, it will not boot
