I posted stuff around my school looking for the owner but i did find it in the street and I go to school at CCNY so the chances are very low... I feel bad but its blank it has nothing ill post some pics soon and ill try to open it up but im a little afraid too.

Yeah, at least make a small attempt to locate the owner before making it your own property. There could be months of someones work on there!

Why dont you post a picture, or take it apart and photo the pcb.

Hand it into the school's reception as lost property!

You can try using a GBA flasher of some sort. Most likely, the cart is corrupted or something if all it shows is the nintendo logo. Who knows if it can even hold the data.

Hey I found a blank GBA cart at my school the other day like it just shows the Nintendo logo and thats it it has no markings but I wanna know if there is a way to check if there is anything on it at all is there some kind of a test cause I wanna see if I can copy my LSDJ data to it just as a back up other then the backup already on my comp. Also what are your ideas on what I should do with it? Any thoughts?
