I always try to enter in a 1.4 server
The BugHunter/EVO patch doesn't work...(it gives me a memory allocation error/a server message "Server is using protocol 16" ... this crack doesn't need the latest patch, it should work with the old 1.3 -> see the crack info)
With the Fl@sh one, I can enter in a server using 1.04 version (my jk2 copy patched with same official version+game cd inserted in my drive) of the game, but after a few second it kiks me with the "CL_server_etc ... invalid server message etc"
