[][1]DGEN is an open source Sega Genesis/MegaDrive emulator that is
available for many operating systems. This port of DGEN is for Mac OS
X 10.4 and higher (Intel build) and Mac OS X 10.3.9 and higher
(PowerPC build).

There was an official port to the Classic Mac OS 9 operating system in
the late 90s/early 2000s, which is still available on on the
[Macintosh Garden][5]. However, this port is not Mac OS X native,
which also means it does not run on Mac OS X 10.5 Leopard PowerPC due
to the lack of the Classic environment. Mac OS X 10.4 Tiger running on
Intel systems can not even run the old port since Rosetta can not be
used with the Classic environment to run Mac OS 9 software. Besides
the previously stated reasons, the last Mac OS 9 release is stuck at
DGEN v1.1.7. The current and latest version of the DGEN emulator is
v1.3.3.

This DGEN port also includes Xbox 360 controller support already set
up for use with the [Tattieboogle Xbox 360 Controller Driver][6]. Read
the Usage section for the controller button mappings and info on
setup.

Usage

### System Requirements

This port of DGEN does not use assembly optimizations as they are not
available on Mac OS X. A high end G4 or better is recommended. Any G5
or Intel Mac will run DGEN great.

Download and unzip the latest release for your PowerPC or Intel Mac.
`Dgen.app` is a portable application, and can be ran from anywhere.
Double click `Dgen.app`, and you will be presented with the following
options:

 * `About` \- Displays the version number of DGEN
 * `Configure` \- This will open the `~/.dgen/dgenrc` config file in
   a text edit window, allowing you to make changes to the settings
   of the DGEN emulator.
 * `Configure Xbox 360 Controller(s) Support` \- This will overwrite
   any existing `~/.dgen/dgenrc` config file with the default
   configuration plus Xbox 360 Controller button mappings for up to 2
   players/controllers at one time.
 * `Load ROM` \- This will open a Finder window allowing you to
   select a Sega Genesis/MegaDrive ROM file, which can be compressed.

### Fullscreen

The default configuration is to start in windowed mode. To enter
fullscreen mode, press the `ALT` and `RETURN` keys at the same time.

You can edit the `bool_fullscreen = false` option to `bool_fullscreen
= true` to go fullscreen by default.

### Xbox 360 Controller(s) Button Mapping

Through pure trial and error (there is no key mapping info it seems
for Mac OS X+SDL 1.x+[Tattieboogle Xbox 360 Controller Driver][6]
already available), I have come up with a pretty sane button mapping
for Sega Genesis to Xbox 360 Controller configuration. You can try to
change this to your liking, but prepared to be infuriated by the trial
and error-ness of doing so on your own without my config. Up to 2
controllers will work at the same time with the below button mappings:

Sega Genesis Button | Xbox 360 Controller Button
---|---
DPAD-up | DPAD-up
DPAD-down | DPAD-down
DPAD-left | DPAD-left
DPAD-right | DPAD-right
A | B
B | A
C | X
X | L1
Y | Y
Z | R1
Select | Select
Start | Start


Install From Source

### Requirements

 * Mac OS X 10.4.x PowerPC (targets 10.3.9+) or Mac OS X 10.4.x Intel
   (targets 10.4.x+)
 * Xcode 2.5

Run the `build-all` script in the source code download. DGEN will be
built into a portable `Dgen.app` in the `/Applications` directory.


Changelog

### Release 5 (9/30/2021)

 * Updated libarchive to version 3.5.2.
 * `Dgen.app` is now a portable application that can be ran from
   anywhere, not just from within the `/Applications` directory.
 * Added Intel support for Mac OS X 10.4.x+ to the `build-all`
   script.
 * Added the `Configure Xbox 360 Controller(s) Support` option, to
   automatically setup button mappings for Xbox 360 controllers using
   the [Tattieboogle Xbox 360 Controller Driver][6].
