[525]how to make shops [525]

Hello.
I got a r2hd source and i really need 2 know how to make shops.
I don't want the guide from vitality-scape on runelocus so please someone help me.

There arn't any 525 developers on here (well I havn't seen any advertised or in the project section).

Most of the tutorials released are basic shops that don't work very well.

You should code them yourself.

awww but i really need it :(

simply implement my and serenitys 508 shops....
It will work on 525 aswell, just need to change a few things lawl
