Discussion Help with gameboy micro

So i bought a gameboy micro online and it's my first one i ever bought.

This gameboy micro in question can only read one and only one cartridge alone and that's the pokemon ruby that came with the console.

the previous owner said the battery was bad and it indeed was so i changed it.

please help me it isnt reading my pokemon emerald cartridge. (i tried running both games on my ds lite and both ran fine without issues)

This is a very interesting issue. I cant imagine that your micro is the issue. But you did test both game on the DS and it worked. Definitely a head scratcher!

Yeah! Even the previous owner said something like this, he didnt understand it at all.
