Hey !
This is the Item pack i made for the map Concrete: https://tm.mania-exchange.com/maps/224915/concrete
There are about 230 items. Most are modular. Many can overlap without flickering. If you think the number 9 decal is missing, just use the 6 upside down ;)
To install just extract and place the "_n00by" folder in "C:\Users[YOUR NAME]\Documents\Maniaplanet\Items"
Enjoy :)
