XBMC-Emustation and XBMC4Gamers are both awesome. I use both on various Xboxs I have. You can definitely get CoinOPS and Ninja to appear in the menu. To use it as the default dash, simply make a shortcut using xbeshortcutmaker to the default .xbe for XBMC-Emustation and place it in the c drive. I usually edit the current dash in the c drive to evoxdash_bak.xbe. Then name the shortcut you created to evoxdash.xbe (assuming you are currently using the unleashx dash). This way if you decide to go back to booting from your original dash, just delete the shortcut you added and remove the _bak from the original file.
