You buy it. I wouldn't get memory though. not much games use memory. If your looking to play alot of games get a hard drive ( does the same, but works for most games ) i would order yours online at unclevics.com ( cheapest if you don't mind used .. or new also) and if you want it fast i would recommend a used one at GameStop ( or new) or Walmart.
Simply by buying more memory and installing it in your PC
Clear the cache.
The ps3 usually has more but it depends on the one you buy. Ps3 has more in its highest memory console then the xbox 360
yes you can
No, you must buy a special memory card for the 360.
No.
Yes it has memory cards and hard drives
No, that's like putting a latpop ram into a desktop.. just isn't possible.!
Go right all the way to the purple tab and click memory and you can clear your memory device
There are only 2 versions, original and elite. The difference is that the elite has more memory and doesn't have a flat top. -Rittyl
256MB worth. Witch is terrible!
You can but Hard drives are way better.
Yes, but only if you save it to the XBox360, switch out the cards, then save it to the other memory stick.
