Most mains run checks on the local BMD files (Items, Skills, Text, etc) to make sure they haven't been edited... this makes it ignore edits and still run ;)

Great, thanks a lot!!

hm.. it opens many roads for cheaters. Like changing twisting slash radius in 97d.
will it bypass CRC check for bmd files? I can make russian translation of all BMD files if it will =)

as to the cheating issue...in the client - change push to a custom dll - use dll to code a generic md5 check on the files you want checked, then then poke (sorry for older terms..us OLDSCHOOLS who haven't rev-eng'd in years are a bit rusty) it in. make sure server is modded to use new checksum. :bigsmile: Bit weak on my old skillz, but concepts still apply. (if you dont have md5 checksum generator source, search souceforge...I got some a while back from there for custom app, or the enterprise architect MSDN library if you have VS or VS.net). GL!!!!

P.S. - Someone needs to post f-in olly to RZ!!!! dont have time to try to find it LOL!!!

If you use serverside protection with a launcher & alternative CS (Ex skyteam's anticheat) then you can control what files are require in the client to play the game.
