Hello one more time,
There is Kal-Online launcher unpacked. I think the last time it was updated were 2-3 months ago, but I unpacked it again today anyway.
Do with it whatever you want.
Just to mention: It's little bit faster than packed version (I don't mean internet speed). Protection is removed (Debug-Blocker etc.) so it should require less resources than normal Kal-Online launcher. You can also modify some update settings...
It was unpacked on Windows XP, so it shouldn't have any compatibility issues (at least it works on my both systems - XP and Win7)
Used tools: Olly, Universal Import Fixer, Import Reconstructor
Best regards, Thiesius
