This is SONIC WINGS 2 (AERO FIGHTERS 2), an SNK NEOGEO MVS cartridge, tested.
Very important notice: the reading part of the cartridge was badly rusted. I have cleaned it, but it is still in bad condition. I had great trouble getting the game to start up, and it took about an hour until the cartridge worked properly (no exaggeration). Please keep in mind that this cartridge is still in working condition, but you will need some patience to play it.
