That's what mine looks like that I got today
Color differences, different texture on the cartridge than normal cartridges and mainly NO NINTENDO LOGO of OFFICIAL NINTENDO SEAL
I don't have the proper screwdriver to open it up to see if the board is fake as well.
It seems to save and play fine but...yeah.
Bootleg?
