Hi, don't know if anyone will read this, but here it is:
I suppose installing a custom ROM would also do the trick, but if you want to keep the Ouya ROM (keep in mind that this is not a pretty solution, and that it requires a PC running on the same network as the Ouya):
- Download the ADB tools and install them on your desktop PC
- Activate network ADB on the Ouya (development menu)
- On your PC, go to the ADB folder and type "adb shell am start -n com.xiaoji.emulator/.Entry"
If this does not work, try "adb connect <IP>" with the IP shown on your TV, and then the shell command.
You can create a .BAT file to launch it, which is a cheap hack but works.
