M3 Real - 'No Slot-2 GBA Cart Found'

Hi.

I've got my M3 Real Perfect today, which I'm really pleased with except for one thing.

When I try to load GBA software, I get the message 'no slot-2 GBA cart found'. I've got the GBA expansion cart pushed in as far as it will go.

The slot-1 card works fine. Have I got a duff GBA expansion cart, or is there some other software I need to put on the card to get it to work?

Not to worry, it's working now. Don't know what happened but it's fine.

Please lock the thread, mods.

Thanks.
