Because they are different discs then PS2!
for psp go games you have to download them there is no UMD slot for the games so you cant play psp go games on a psp 3000 unless your psp 3000 is chipped.
There are 500 games for the psp so far and counting
If you're asking whether you can play UMD games in PSP GO, the answer is, no you can't.There's no UMD on the PSP Go. So you can only download games and play them on the PSP GO.
if your talking games /psp/game (or Games I cant remember)music /psp/musicand so on...
Yes, all PSP games are specifically developed for the PSP console so they will all work. The same cannot be said of PS Vita games, Vita games won't work on the PSP.
No the PSP plays PSP games. The PS2 and PS3 games would be too complex to run even if a PSP version was made it has to be made with less capabilities so the PSP can run the program
no you cant because their to different systems designs so no you cant sorry.
no
PSP games are not region locked, any game will work on any region's console. Also, PSP games from England are just EU region PSP games anyway so are the same as you'd buy in Ireland.
PSP Go's have these redeem codes that you put in the psp through psn so you can download them to the psp go's built in memory. the older psp's have UMD's or Universal Media Disk, the older psp's can also play go games, just not as fun.
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.
The PSP 2, or NGP, will not have a UMD drive, so any games you have in UMD format will not be playable on the PSP 2. However, any games that you have downloaded on your PSP 3000 can be transferred to the new PSP.
