fast script .fsc in l2ph

[nab]

i have to use a WP with this scrit in order my walker to work

//Fix ProtocolVersion for Hellbound
//828->831
begin
if (_gAbsNumPkt = 1) then 
if not _gFromServ then begin
_gOutBuff := _gBuff;
_gOutBuff[4] := #$3f;
_gOutBuff[5] := #$03;
end;
end.

but if i try to run l2ph to my walker crash , i gues coz bouth programs inject the walker.exe

so any solutions ? can i use fsc in l2ph ?
