Where are U-boat training missions accessible???
 

I had to reinstall SH4+UBM game due to acquisition of new computer. Of course I downloaded UBM Mission Pack but it does not contain training missions. Could you give me link to such missions?

I remember I had one training mission on previous installation downloaded from Subsim forum: one U-boat hunting three Allied ships near Australia's northern coast.

The other day I looked for U-Boat missions to see if there were any gotchas, like different file extensions for the .tsr file or anything, but I came up empty. So I made one anyway to produce a U-Boat Fast-90 tutorial video. There were no gotchas.

Use the mission editor and it automatically creates the mission with the .misge extension. It gets a standard .tsr and optional .tga file attached. Put all files in a subdirectory with the name of the mission, install in \wolves of the pacific\data\SingleMissions\<your directory>. Works fine.

So I really can't explain why there aren't a lot more.
