For people asking for items:
This thread is for sharing items created with the obsolete ITEM_TOOL and a WiiBrew hack. It was for advanced people who were making their own items.
It was started around 2 years ago when people were hacking AC:CF more actively.

Today, this is obsolete.
The best (IMHO) contributed items have already been turned into OHDLC or permanent HDLC items.
You can easily install them in your game with WiiBrew and EZ DLC Install
