Yes. A memory sick duo
You don't need to modify it, the PSP can save games to the memory stick normally, as well as download games to it from PSN.
Yes, you can play PSP games without a memory stick. However, if you're playing games from PSP UMD's (little PSP games in cases). If you want to play games saved in your PSP's hard drive, then no. So, pretty much by UMD, you can play games without a memory stick in your PSP, but you'll be unable to save.
It has a small amount of internal memory, but you need a memory stick before you can save games.
To acess the root of your memory stick you must connect your PSP with a USB cable. The fldr that has PSP and MS_ROOT is the root of your memory stick. Sooo... if you wanna save anything to the root of your memory stick...SAVE IT HERE ;) It's the folder that pops up when you plug in your PSP.
Nothing. The memory stick is for you and the PSP to store data on. All the PSP's system files, the firmware, is coded into its internal memory. You will need your PSP to format the stick, and after that it will be able to save games, or you could load music onto it for the PSP to play, etc.
Theres never really been a console or handheld where you save it to your disk, except the Nintendo DS's (they arent disks but more like chips). But on the PSP you save it to the memory stick.
You do not 'need' any kind of memory stick in the PSP for you to play games. However without it, you are unable to save game data. So while it is not mandatory, it is pretty much essential.
no you just need to be in range of a wifi spot. but a memory stick can save your games and you can play where you left off in the game with out the game in it.
Depends If You Wanna Save Games/Movies/Music/Saved Data
You can copy games from one PSP memory stick to computer and then copy to another PSP's memory stick. Make sure you put the game on the folder 'GAME' on the memory stick.
Yes, you need a memory stick for all PSP's except the PSP Go which comes with a 16Gb hard drive built in
All psp games can be used with a memory stick. The memory stick saves your progress on your games. You can buy a memory stick from wal-mart for about 10 or 20 dollars.
