Product Description:

The Air Jordan 6 Carmine returned in its original form in 2021. The nearly 20-year-old colorway first made its appearance in 1991 during Michael Jordan’s ’91-’92 season and brought in a new form of color blocking to the signature silhouette.

You need ReSkate and your own copy of skate. on Steam.

Search for Jordan 6 Retro Carmine and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.
