I have some spare time so I will copy the entire contents of the leaflet that comes with the freeloader.
FREELOADER - For Nintendo Wii
For use with euro consoles
Introduction
Freeloader for Wii uses proprietary technology to enable your console to play import games from other regions. Using freeloader for Wii you can now, for example, easily play japanese or U.S. games on any European console.
We recommend you always buy a game designed for your own region wherever possible due to language differences and extra features ect. However there will be occasions when you simply can't obtain a game, or are not prepared to wait many months for a foriegn title to be released in your region

. In these cases, Freeloader for Wii is your passport to playing games from any country on your console.
If your one of the many gamers that bought an imported console and you now want to play games from your own country, then Freeloader for Wii is also ideal for this task.
Whichever way you use Freeloader for Wii, no modifications to your console are needed and your console's warranty is kept intact.
Now read on to find out how to get the most out of your Freeloader for Wii.
Getting Started
Follow the simple instructions below to start up Freeloader for Wii.
If the game that you wish to play is from an NTSC region then you may need to first set the display settings to 60Hz. For best results. This setting is found in the Tools Menu on your console.
Insert the Freeloader for Wii disk and it will automatically load and run.
Multiple colour bars on the screen will indicate that Freeloader for Wii is in operation.
The colour bars will appear twice then the drive will stop.
Eject the Freeloader disk and now insert the game disk that you want to play. The game will play as normal.
Game Upgrades
Most game disks have an upgrade program which is loaded before the game application itself.
The purpose of the upgrade program is to update your console, where necessary, with new firmware modules.
When loading a game from another region on your console this upgrade program may have unpredictable results if loaded.
Freeloader for Wii will prevent this upgrade program from being loaded and will only load the main game application.
A number of games will not function unless the upgrade program has been first loaded and so Freeloader has an alternate, selective load method for these games.
Alternative method
Insert the Freeloader for Wii disk and it will automatically load and run.
Multiple colour bars on the screen will indicate that Freeloader for Wii is in operation.
The colour bars will appear twice then the drive will stop.
Eject the Freeloader disk and then RE-INSERT the Freeloader disk once more.
The multiple colour bars will appear twice more and the drive will again stop.
Once again eject the Freeloader disk and now insert the game disk that you want to play.
The game will play as normal and this time the upgrade program will be selectively loaded.
Please be aware that allowing the upgrade program to run may, in a number of cases, still cause unwanted effects.
It is advisable to check through the FAQs at
www.codejunkies.com BEFORE you load any game that requires an update program!
Since any game updates can create unwanted results or even incompatibility with the Freeloader, it is recommended that all new games, even ones from your own region, are loaded via Freeloader's alternative selective upgrade method.
CAUTION - Online Upgrades
Freeloader for Wii works with all current versions of the Wii firmware at the time of its release.
No guarantee can be given of compatibility with future firmware releases so if Online Updates are performed on your console this may prevent Freeloader from functioning correctly.
We recommend that you consider the benefits of any Online Upgrade against the possible loss of compatibility with Freeloader and its functions.
