How is it not working specifically?

thanks for the replyIt just says "loading..."

Try backing up your data (copy it somewhere), and reformat your MicroSD.

It's working now, Thanks alot for the tip!!!

i have a question how do you reformat your Micro SD card?the difference is that there isn't any games yethelp pls.

Right click the removable drive when you connect it, and go Format.

how come it says " windows cannot finish the format" ?

Make sure you're not doing anything to the files on the MicroSD. Try rebooting.

i rebooted my comp and it still doesn't workthere also this fileits a pokemon platinum romwhen i take a loook at it it says " 0 bytes"
