GBx games to work on DS reader?

Hello. I have been searching the site and I don't know if I missed the post or not, but I was wondering if it is possible to have the older GBx games run using a DS reader? I have the R4 SDHC chip and it has the latest offical firmware, but any game that is not DS will not run. Is there a DS reader out there that does allow playing of old GBx games?Thanks.

You can play old Gameboy and Gameboy Color games using LameBoy emulator for the DS. You can get it at www.linfoxdomain.com/nintendo/dsIn order to play GBA games, you need to have a Slot 2 device like the EZFlash 3 in 1 (Slot 2 is the Gameboy slot on the DS).

Thanks for that information.
