etabeta78 a2b6866d52 (MESS) gamegear: moved GG-SMS scaling from VDP file to the machine file;
undone the specific X-Scroll timing introduced to fix Chicago Syndicate, for Game
Gear, because it causes problems with the games Sonic Drift 1 and 2; reduced
the amount of duplicated code in the VDP file. [Enik Land]

out of whatsnew: gamegear units modded to output the image signal to a TV are able
to show games using SMS compatibility mode in full screen, without scaling, while
native GG games are displayed in a centered, smaller image, that is surrounded by
bigger borders. Also, GG units that have the original LCD display replaced by another
LCD display model (not just the back-light) also displays SMS compatibility games
without scaling, and native games with borders. This suggests that the scaling
isn't performed by the VDP and therefore motivated the moving of the scaling code
in this commit.

What is MAME?

MAME stands for Multiple Arcade Machine Emulator.

MAME's purpose is to preserve decades of video-game history. As gaming technology continues to rush forward, MAME prevents these important "vintage" games from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the games are playable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?).

What is MESS?

MESS (Multi Emulator Super System) is the sister project of MAME. MESS documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators, as MAME does for arcade games.

The MESS and MAME projects live in the same source repository and share much of the same code, but are different build targets.

How to compile?

If you're on a *nix system, it could be as easy as typing

make

for a MAME build, or

make TARGET=mess

for a MESS build (provided you have all the prerequisites).

For Windows users, we provide a ready-made build environment based on MinGW-w64. Visual Studio builds are also possible.
