IF THE ACHV IS NOT POPPING FOR YOU:
1. Exit the game. Menu click on the game to QUIT officially.
2. Start up a new game, start it officially, then Exit and QUIT officially.
3. Start up GONE HOME again (a new game) - and beat in 1 minute. Mash B.
4. Achv should pop at Main Menu screen!
This is of course assuming that you are beating in less than 1 minute but the game is glitching and not popping.
