simple yes or no question about r4?

With a r4 can u download gba games too.

You need a Slot 2 device (that plugs into the GBA slot of the DS) to run GBA games.

btw, you can find this info on the web. If you find the right info site.

that's why he asked here dude-it's easier to google if you know what exactly to type.

GBAtemp.net has some Reviews (click Reviews tab) on various Slot 2 devices. I believe you need to have an account to view them now though =\
