From Homestar Runner Wiki
Sega Tapes, the cartridges used by the Sega Genesis/Mega Drive game system, have appeared in the Homestar Runner universe. While none of the characters has been seen playing any of these games, Homestar Runner once attempted to use a Sega tape and controller with a waffle iron, with delicious results.
"Tape" is a somewhat common misnomer for cartridge, referring to the Sega Genesis cartridges' resemblance to cassette tapes. The cartridges for the Sega Genesis used semiconductor-based ROM chips for data storage, not spools of magnetic tape, so they are not actually tapes.
- Debut: Email anything — Sega tapes with Videlectrix game names on them are used as coasters for glasses of Melonade.
- Teen Girl Squad Issue 8 (Easter egg) — Tompkins steals a Sega tape with the game Road Rash on it.
- Email more armies — Homestar says that "the last time I fired up one of my old Sega tapes, it made me a waffle."
- Email slumber party — Strong Bad goes over to Homestar's house and hopes to play mature-rated games such as Blood Bleeder, Head Chopper 2, Scab Wars, and Blistergeist. A few other Sega tapes are lying around, including Throat Rip and Saliva Quest. Homestar informs Strong Bad that those games are "off-limits" and that they're only allowed to play Clapping Party.
