It's a bit more work to add them but its possible.
You need to
1)unzip the file
2)upload the .swf file to the arcade folder
3)copy the .gif file and name one game1 and one game2 - upload those to the images folder where "game" is the name of the gam
4)open the text document, go to Add Games in the top part, and enter all the settings mentioned in the text document
GName is the exact name of the .swf file
