Here's something interesting that's just Korean. It's Sonic 2 , which you'll know for the Game Gear, but here it's a cartridge for the non-portable console, the Mark III. It uses the same artwork as the PAL box (shown here). The cartridge is pretty tall, not like those short rectangle Genesis ones. You can see how big it is compared to the system in the bottom photo. The top has foil & Korean writing, likely to be the title.
