Just downloaded this game today so decided to make a multiclient. it a sloppy patch but it works.
1. Open Nksp.exe in olly(make sure you have the 'Ultra String Reference' plugin).
use it to search for ASCII text look for this(see image below) and double click it.
2. above it change the JNZ to JE(the address is higlighted in grey in image below). copy to executable all modifications and save.
3. create a shortcut to Nksp.exe and in shortcut properties add 'LastChaos run'(not LostChaos sorry) at the end of target, run game from shortcut.
tested it today on US version and it works.
