The Powersaves is shaky, and I use it mostly for backing up my games, as that barely ever disconnects, unlike going to the Codes tab section. I read a lot about how getting a different USB cable would work. So I got one from Amazon, a longer one, which is good for me, and things are better, but not perfect. Good enough for backing game saves, booting cheats? Just hope the process is done fast, the longer it takes, the more I fear it would disconnect.
To be specific, the Powersaves does work with my X, Y, and OR. Haven't tried it on my AS yet. Oh and blowing on the device, that old school superstitious thing that magically makes any cartridge work. I do that with the Powersaves.
