*walks in casually...*
Coincidentally, someone posted a bunch of links to extra levels in the forum of my "JK & MotS SP Levels List" project on the Hub the other day, and by chance I was doing one of my occasional visits so I spotted it. It actually inspired me to update the list, and I was all set to re-post it today, and Bam! The Hub is gone!
If anyone is interested, the new list (of all known released JK and MotS SP levels, with download links) is here: https://drive.google.com/file/d/1AqbitNv_7bZXUTFE3KIBLZiKsGrqZ8g7/view?usp=sharing
Most of the new levels are either available at Massassi anyway (released since I made the list), or really old and pretty poor. However the main highlight is that I managed to find a copy of A Jedi's Quest 2 on an old CD-R; that was one I had thought was lost forever. Nikumubeki, I seem to remember you saying you'd like to play it, but that must have been about 10 years ago now, when I originally made the list! Anyway, if you're still interested, now's your chance.
The only one I'm now missing a link for is SavageX's Space Soldiers 3 SP level. Annoyingly it was on the same CD-R as A Jedi's Quest, but the file seems to be quite heavily corrupted. I uploaded it anyway in case anyone can do anything with it, but as it's a self-extracting EXE inside a zip, there's probably little hope of recovering it and we'd need to source a copy from elsewhere. I think I asked SavageX a number of years ago but he never got back to me...
