Relic Castle

I'm starting the development of a game and I came across the Bag System - BW2 Mod (created by shiney570), but it does not update the project any more.
I am using v17 and have already added other scripts.

Link of the project: https://web.archive.org/web/20161215064652/http://reliccastle.com/forums/showthread.php?tid=1090

Can help me please.
