VOB is kinda simmilar to SF3 but SF3 is a way much better coded as it doesnt take so much resources as VOB does. But VOB isnt a so much found Protection at all. The last Games i know are Port Royal 2 + Arena Wars from Ascaron and Holiday World from Brigades.
The similar thing is they both used special drivers but VOB can always be copied with the same trick what for SF3 isnt possible. SF3 you either have a good burner or are skilled enough to patch the installed .sys file from SF3.
The difference is: VOB from Ascaron is filled with hidden checks (crc, size, date, etc.) or like in Arena Wars a non original exe cant play online in any way. Maybe u ask the main creator of SF3 as he did the most VOB cracks before
Its a lot of work too and their are to less people that try themself and improve on trying. Most people simple leech via p2p and dont care how much work crackers invested and that they might need help and new talents.
Its like in sports ... only if no new talent arrives the ppl start crying ... but i dont see alot of people here that exchange infos about their trys .... its always i nedd, how do i, and so on ...

i hope it gets done before the russian freak finds something new
as
i hate games like D-Day German where you dont see an end during debugging
Good luck on it.

btw. Tages is a lot harder as you hae to play the game to finish as it gets only decrypted level by level
