SEGA 콘솔 클리너 - SEGA 제네시스 / 메가 드라이브 청소 카트리지 by 1UPcard™

Bought this after my Genesis started skipping on the title screen of Sonic, and the included cleaning solution with the cartridge took care of it in two passes. It's nice that you can just slide it in and out like a regular game, no disassembly required.

The cleaning cartridge slid right into the pin connector on my old Genesis and after a few wiggles, the static and glitchy graphics disappeared from my games. It's a simple fix that saved me from having to take the whole console apart, and now even my beat-up copy of Sonic boots up clean.

Still working well after a dozen uses, and the card fits snugly enough to actually scrub the pin connector rather than just slide past it. Only gripe is there’s no cleaning solution included, so I had to grab my own, but the result was worth the extra step.
