Madcows Roleplay

Hello everyone,
you probably know all the famous Madcows Weapons coded by Worshiper …
These weapons were coded for gamemod Madcows Roleplay for Garry’s Mod 10.
Obviously you can imagine with Gmod 13, Madcows Roleplay has some errors.

So is anyone could help me to put it on gamemode feet.
I already resolve various problems but some are unfortunately exceeds my knowledge and

So if someone could help me with these problems it would help me hugely

This sounds like a bigger project than you think, look at some of the GM12->GM13 conversion threads or put up a job at the hire thread, nobody will do this for free/admin/donations/etc by the sounds of it.
