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
No, Nintendo is just the oldest home console developers. Sony are older, but they started making consoles after Nintendo so they don't count. Nintendo is the oldest video game company. Nintendo was founded in 1889 and Sony was founded in 1946. Sega was founded in 1940 as Standard Games which would make it older than Sony also. Nintendo has also been in the video gaming business longer than any current company. They started in the video gaming business in 1973 when they released the the light gun arcade game Laser Clay Shooting System. In 1974 Nintendo secured the rights to distribute the Magnavox Odyssey game console (which was the first home video game console) in Japan. In 1977 Nintendo created it's first home console which was called the Color TV Game 6. It was never released outside of Japan. In 1980 they released their first handheld console the Game & Watch. It was a series of 60 different handheld video game units released between 1980 and 1991. The first one released in 1980 was simply named Ball. It was a game where you juggled balls in the air for as long as you could without dropping any.
Any router should work. I prefer using wired versus wireless for the additional speed.
