See you can do it when you actually try, which is the purpose of this section.

Simple rule :

- Always keep the first byte
- Put * for everything else.

Do that until you get an unique signature under IDA.

It should be more easy/fast to make signatures and also reliable ; though signature might gets longer, but that's not an issue itself.

can we hook a function from any metamod plugin using orpheu? I mean till now what I have observed is people have been posting about only functions that are registered within swds.dll ..... what if i want to hook something in a metamod plugin eg. SB Guardian

You can. At least using latest orpheu version, it should auto register any metamod libraries. From that, just a matter to use it's name in config file. You should be able to see a list using "orpheu config" command, at the top.

You have to use tricky way, like finding a function where it's used, then retrieving it from there by checking bytes.

I put a code to return the value of argument on SV_ParseVoiceData function and got a 9 digit number. Does it have any relationship with svs_ptr?

Don't do random things if you have not idea what you're doing.
If you retrieve svs from SV_ParseVoiceData, you have to retrieve it's address (4 bytes) which is used a the top of function. That's why I said you have to count bytes.
