No go, I managed to get retroplayer installed in dev mode but all it did was kick me to the store, and the appx i got from the store with fiddler won't install, i don't know if the version being deployed to the xbox is a different build or if there is just some special install privileges it receives from MS. I am not very knowledgeable in all this though, I do believe from what I gathered it wouldn't be difficult for someone more experienced to either get a version working in dev mode, make a work around in retail, or at the very least be able to determine what the current road blocks are.
