This is my first character for Shimeji, a customizable desktop buddy system thing. Red below for instructions on how to install and use. If you have any questions or problems, tell me and I'll try to help.
1: Download the Shimeji program here: [link]
and extract the folder inside to where ever you want. (if you already have this move onto step 2)
2: Click the "Download File" link on the right and extract the Mario folder to the img folder in the Shimeji folder.
3: Run Shimeji-ee.exe. A window will appear with a list of characters. Make sure Mario is checkmarked, then click Use Selected to use Mario (and whoever else is checkmarked) or click Use All to use all the characters.
