hello- I like doing this kind of stuff and learning more and more so I made the file you need for this to work
follow the steps.
1. download this file here ------>
https://www.dropbox.com/s/d5lbjv1e9cv3qwo/Home.xml?dl=0
2. wont take much for this about a second, then ftp to your xbox.
/Q/skin/Xbox-Classic/
3. make sure you go to PAL and PAl16x9 rename the home.xml backup or make sure you have a backup of this skin, safty first
so please do this then move on.
4. once you done the backup go and drop the file you downloaded in the folders PAL and PAL16x9 once you do this you will be done, and then go and try this on your xbox-classic skin, make sure you restart your xbmc4xbox so it can take effect.
5. since you might have this folder named Aracde Emulators I figure, if you already have it added to your programs, it should of worked right out of the box.
6. if you already have this add and it worked, then skin this step, if not, in programs add source and add your folder named arcade emulators, now restart xbmc and see if this takes effect.
7. open a drink of what ever you like to drink and enjoy
if you need help or it didn't work please write back on here and im sure someone will help if not ill get back to you, thank you
once again enjoy!!
