If I'm understanding the question correctly...no.
Only PSP games will work in the PSP. Vita (or any other handheld system) games will NOT work.
Scott Pilgrim vs The World is not on any handheld system. It is only on the PlayStation 3 and Xbox 360.
Any game from any region will work on any console from any region as long as they're the same language....In other words, 'yes'.
If it is an XBOX 360 game then it will work on any XBOX 360 console.
Any Ds game works for the dsi, there isn't any difference.
This game isn't compatible with the console that plays PS2 games or any of the others
Yes, if you google search "angry birds handheld game" , you will come back with a small handheld console game in the search results, kinda like those cheap poker and slots games you can buy at walmart. I found one on amazon for $24. If you dont have any luck, you can also download them on PC and Mac, as well as Ipads and a number of other electronic devices.
Yes. Any Wii remote will work on any Wii console, regardless of color
Probably going to be the original Nintendo. I would say that is the PlayStation 2. It has the longest life of any console as they are still making games for it today. It has the most game titles available of any console. And it has sold the most games of any console to date.
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.
IT does for Guitar Hero 3, World Tour and Metallica. Not for Guitar Hero 2
Any router should work. I prefer using wired versus wireless for the additional speed.
It is not, due to the lack of buttons on Game controllers.
