fact: Tages can be cracked. But its difficult. Since Crack/Warez groups are always racing to be the first one to release I think they will definately spend all the time on cracking Tages just to be the first one
Most certainly it'll take some time/weeks but sooner or later 100% proper cracks will appear.
As for XIII: You dont even need the 20MB version. There's a small version of some kb which does the same thing.
