LostSaga 2014 client launch line (LosaDev local setup)

lostsaga.exe "<check>?<launch key>?<options>?<ip/port number>"

check       EDEW3940FVDP4950,10,20,30,1,autoupgrade_info.ini,300,0,1,938400398
            Only the first field is checked. Field 6 names the info\ ini file.
launch key  hex( Encode15(loginKey, loginKey) ) + hex( Encode15(userID, secondKey) )
            loginKey  = userLoginDB.encodeKey of the account (15 characters, set before every start)
            secondKey = newest define_encode_key.encodeKey (under 16 characters)
            Encode15  = SEED-CFB, see ls_gamesvr\Util\ioEncrypted.cpp (the server only decodes).
options     0   (any non-empty value; the client always reads rs.iop + map.iop)
ip/port     64-bit number: bytes 0-3 = game server IPv4, bytes 4-7 = CSPORT, little-endian
            = a + b*2^8 + c*2^16 + d*2^24 + port*2^32   for a.b.c.d
            192.168.1.10 port 14009 -> 60168364730560

The game server must be the address it listens on (the PC's LAN IP), not 127.0.0.1.
The login key is used up at logout (the server writes a new one), so generate a new
launch line for every start.
