There is a minor, but handicapping typo in the TSF one. The following key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Epic MegaGames\Jazz Jackrabbit 2 Secret Files\1.24\List Servers]

Should instead be:

[HKEY_LOCAL_MACHINE\SOFTWARE\Epic MegaGames\Jazz Jackrabbit 2 Special Edition\1.24\List Servers]

Beyond that, good job. Both BlurredD and I have created patches, but did not see it necessary to upload quite yet. This is as good of a time as ever.
