Nintendo DS / GBA compatibility

My 8 yr old says GBA games are compatible with the DS.

Is this true? Are there issues?

The DS has a GBA slot. So, yes it’s true, and no there aren’t issues. It’s only backward compatible with GBA games though, not GB or GBC games.

And I believe some things are not supported, such as the card reader. And multiplayer does not work for GBA games.

Zelda : Four Swords doesn’t work on the DS. It’s the only GBA game I’ve heard of that just plain doesn’t work, though. Then again, it comes with A Link to the Past, which works fine, so it’s not a complete loss.

It doesn’t work because the game is multiplayer only and the DS doesn’t support GBA link cables.

thanks guys.
