Introduction
------------

For most of the MegaDrive's life, cartridges were produced without any sort 
of territory protection. Some games even had multiple languages for different
territories, Neo Geo-style.  However, later in the MegaDrive's life, Sega and
several third-party developers decided to start implementing a software 
territory lock-out to keep people from playing games outside of the territory
they were intended for. The software routine is different in each game and 
always resides in a different part of the program code. Basically what the 
routine does is to check the hardware address in RAM that specifies what 
kind of MegaDrive the game is running on (Japanese, US, European, etc), and 
if that doesn't match the intended territory, the game locks up with an error
message.

What this list does is list MegaDrive games and states whether they contain 
a territory lock-out or not (but its far from complete). My purpose for doing
this is simple, I own a Sega Nomad and live in the UK. Therefore I thought 
it may be useful to know whether a games going to be compatible or not before
I purchased it.


How do you know?
----------------

The only way to find out for sure is to test them yourself. All the games I 
own personally have been tested on my Nomad, everything else on the list was 
tested using DGen.


DGen testing
------------

DGen is a MegaDrive emulator which contains an option to select the country 
of the machine to be emulated. By using this I've been able to test whether 
ROM images contained a territory lock-out or not. This method probably isn't 
as accurate as testing it on an actual machine so I don't take responsibility
if some of the following results prove to be wrong.
