M3 ds real help

Your textI recently bought a m3 real ds with rumble pack expansion, the ds games i have put on work fine, i then followed a guide to add gba games, then when i get to playing the games there is a large buzzing noise, the battery goes to red and it comes up with a message about slot 2, how do i fix this and add gba games? thanks

 

You need the ram expansion to play GBA games. Rumble pack is only for rumble in some DS games.
