This fourth .REG file (import3.w2k.reg) is NOT part of the challange, I just put it in there to illustrate the UNICODE issue with Windows 2000 exported .REG files.

Anyway, the challange only requires you to import the provided .REG files. It doesn't expect you to import any and all types of .REG files.

Nevertheless, if anybody would be willing to write a complete UDf for this, then all registry types and escape sequences must be taken into acount.
There are two types of vessels, submarines and targets.
