Like the title says the M3 Real is saying that the GBA slot2 device isnt there. I believe it is just a random defect, but other might have had this issue too. If so what was your solution. Kickgaming is willing to exchange it for another GBA pak(so I can can keep the Real itself with me, which is really nice)They also replied to me within 15mins a giant thumbs up there. I tried using 2.5beta 2.7 and 2.7d none of which helped.(all downloaded from here, especially since the m3 site has reached its limit. tried Tetris world and Mario Advanced 4(SMB3) both usa. Also there is a scratch on the sticker label about half way down, and the screw in the back fell out, though it still holds together fine. I believe the problem is with the board, the "teeth" dont come down as far as a normal cart or as far as the rumble cart, and so leaving a bit of unused board below them. Looking at the m3 real review The teeth on that one seem the right length so again I believe it is a random defect, just thought I let everyone here know in case they have the same problem and also to let the m3/g6 team know since they come here. Edit: The Real is able to play normal GBA games which also points to the pak. 2ndEdit: Other than that I love it. Nice graphics. Easier to get started(just moving the system folder) Rumble for the second I felt it was nice(I dont have any supported games so I only felt the split second rumble at start up. It even has a power saving mode if you leave it alone for a moment(I guess like a DS open sleep mode, only in the menu though) so I give it a 7or8 of 10 would be 8-9 but I havnt tested the GBA pak so that other point will come later.
