Gameboy advance games

[whoops]

DS is 6 and doesn't read very well yet.
We bought him a gameboy with a Pokemon game for Christmas but he is struggling with the game.
Can anyone recommend good games he can play by himself so that I am not spending all my time sittng an reading what the game is doing so that I can do stuff with dd too?!

GBA games are getting quite hard to come by now unless you get preowned or can find them on sale. Cars doesn't need much reading or Sonic. ds also had Incredibles, Monsters inc and Nemo (some reading required btu you can skip and at times hard to manouevre) at that age.

My DS has Spyro and a Power Rangers game. he needs a bit of help sometimes still.

Thanks,
I think we might go for a Sonic game as he has seen it on a friends
