The PSVita does not use UMDs, your games either come on the new PSVita Game Cards, or are downloaded from the PSN.
No, it takes its own PSVita game cards. It is not compatible with PSP UMDs, but an increasing number of PSP games are being made available on the PSVita's PSN store.
No, the PSVita's games look more like memory cards, it does not use UMDs.
You need to have downloaded the games from the Playstation Store. The PSP UMDs do not have a slot in the Playstation Vita
Yes, but only downloaded ones. The psp go doesn't have a driver for UMDs.
The Playstation Go has to use downloads while the PSP can use UMDs or downloads
YES. As long as the game for your old PSP was downloaded from the PlayStation Network. UMDs will NOT work in the PSPGo. The new games can only be downlowded.(PSP go can text)
no it well not have any umds.
You do not need to have a Memory Stick inserted to play games if you have UMDs.
psp go is smaller has internal memory of 16 GB and requires no umds to play games normal psp is bigger requires a memory stick and uses umds to play games see the difference now?
This really depends on each individual. Personally I like the PSP Go because it is slimmer and I don't have to carry around UMDs as you do with the older model PSPs. You can get pretty much the same games for each one. The PSP Go is really just smaller and has the capability of holding downloaded games whereas you have to play games via UMDs with other PSPs. There aren't any graphic enhancements or anything else it's really just a more portable handheld than it's predecessor.
The Ultra Mini Disc is a small CD inserted in the PSP to play games. I think that there were even movies that came in UMDs for the PSP.
PSP Go can only download games and the PSP 3000 can download and play UMDs. If you need to play UMDs then the PSP 3000 is the choice but if that doesnt matter to you then go with the PSP Go.
