i dont think this feature is directly in MG. However, im sure you can achieve this with a VB Script or Batch file. Or since MG really just loads the emulator you should be able to just load the emulator with said game on boot instead of mGalaxy. Then have the emulator run a command on exit. that ...

Yeah i wanted to purchase a couple themes from the store however it came up with some kind of paypal error. You might want to check our your PayPal account.

Thank
