A lot of Money and Items
Plug a controller into socket 1 and another into socket 3 and then press the z button on the controller that's in socket 3. After that, press start. You will have 99 of each tool, 99 of all the records, almost all of the seeds, a bunch of cooked food, and other things. If you sell all the things you don't want or don't need then you will get a lot of money! You can keep doing this over and over.
