Game boy i recuest to my momy to buy me a new game boy advance

Brand new Game Boy Advance SP costs around $250. You should also check Nintendo DS, you might like it better.

go to gamestop.com if they dont have it check at a local video game area in your city/town/state you live in or you can look online to purchase it i hope this helps.

Amazon has some use at a decent price.

Hope this helps.

Will cost more to have the game boy repaired. better off buying a new one.

you either play them under direct (sun) light or attach some kind of external light like a worm light for a game boy color/advance, but the light isn't evenly distributed. i have a halo light for my gb advance--better than nothing.
game boy advance sp has a front lit screen.
GameStop sells game boy advance sp for $40.
hope this helped some

Depends on which country you are from
Try your local trading post for second hand games, but your best bet is eBay. Typing "buy nintendo games" on google seems to pull up a lot of responses.
also try the nintendo website - they have a list of major online retailers here:

Burnout Legends was scheduled to come out for Game Boy Advance in 2005 or so, but it was cancelled.
