Ill help u, its a very simple process..just find a character on the internet, get some sorta program like winrar, if you are downloading from megaupload just enter in the big bold 3 letters at the top right, then it will say click here to download, after u click it you'll see a count down, after the countdown click on the thing again and save the file into your documents, or save it directly on your desktop...right click the saved file and use the "extract files" option, after u extract it put it in your character folder...heres the tricky part, go to the data folder and there should be a folder titled "EVEvolve" or something like that, just copy the contents of the folder and put it into your data folder, and u probably dont want to overwrite the previous system and select def files, so rename your old "select" and "system" files into something else, now u place the system and select from EVEvolve into your data folder, access the select file with notepad, then scroll down to about the middle of the file, it should say "MIDPOINT" now u replace a "randomselect" with the name of your downloaded character, make sure the name of the character's folder matches the def file inside the character's folder, after replacing the randomselect, save, exit, and try playing winmugen, if it doesnt work, try repeating the process

IMPORTANT NOTE: THIS ONLY WORKS IF U INSTALLED THE EVE BATTLE SCREENPACK, IF YOU DID NOT INSTALL EVE BATTLE, THIS IS COMPLETELY USELESS TO YOU
