Launching Jazz Jackrabbit 2 through Internet Links

There are many scripts on Jazz Jackrabbit 2 websites that promise to launch you directly into current multiplayer games such as gip.php. One feature that is be present in all of these scripts is the link that downloads a ".j2i" file. However, if you copied JJ2 from another computer and didn't install JJ2 directly from the CD and then apply the patches j2i files will no longer work. I've put together a nice little registry edit so everyone can make full use of the gip scripts.

Overview of Jazz 2 Internet Links

Jazz Jackrabbit 2 Internet links are simple text files containing the IP of the server you wish to join. When downloaded JJ2 should be launched automatically as jazz2.exe -j2i and start you connecting to the server. This is very useful and handy, but it presents a problem for TSF. TSF needs to be launched separately from 1.23 and the gip scripts will not open TSF through a j2i file. Therefore, all gip scripts should now send ".j2si" files when a game is TSF. The J2SI files, identical to J2I in all ways except the extension, will launch TSF directly from a gip scripts.

Load Jazz Jackrabbit 2 with J2I (Jazz 2 Internet Link) Files:
Note: you are required to enter the location of your JJ2 installation into the textbox so the registry patches are be able to register a file extension with the correct program. The registry edits require it locate the correct jazz2.exe (TSF or 1.23).

Load 1.23 with J2I files (you do not need this if you can join 1.23 games from gip scripts already)
Enter the location of jazz2.exe version 1.23 on your computer. Please use backslashes (\) when changing directories.

Load TSF with J2SI Files:
Enter the location of jazz2.exe version 1.24 (TSF) on your computer. Please use backslashes (\) when changing directories.
