listenserver do not use swds.dll, it uses sw.dll and hw.dll which build into cstrike.exe 's proc, so it's a little more difficult to patch it, because you only can use signatrue scan the address you need to start the patch, and the signature is not the same as swds.dll in some functions, usually not the same.
so you can do
get_module_handle("cstrike.exe") example, and start signature scan at this address
and use mem_infomation stuff to get the size of image or something...
