For fans who want to explore Sega’s 16‑bit library beyond what Nintendo offers, legitimate alternatives exist: (available on Switch eShop, PlayStation, Xbox, and PC) includes over 50 games in a single purchase, often on sale for a modest price. That collection features titles not found on Nintendo Switch Online, including Sonic the Hedgehog , Sonic the Hedgehog 2 , and ToeJam & Earl , along with robust emulation features like save states and screen filters.

This is where the terms and lab exclusive enter the discourse. In the Switch hacking community, an NSP (Nintendo Submission Package) is the digital file format used for downloadable titles from the eShop or for game updates. When a dataminer extracts a retro game from NSO’s encrypted files and shares it, that ROM becomes a “lab exclusive”—a term borrowed from the sneaker and streetwear world (a “lab” exclusive being a rare colorway only available to insiders) but applied to digital code. segagenesisnintendoswitchonlinenspromslab exclusive

The NSO service offers a polished experience: save states, rewind features, and online multiplayer. However, it has limitations. The library is curated, meaning many obscure or cult-classic Genesis titles remain unavailable. Furthermore, the emulation is "locked" to the Switch ecosystem—you cannot transfer your saves or play these games on other devices.
The exclusive partnership between Segagenesis and NS Proms Lab offers numerous benefits for both parties. For Segagenesis, it provides an opportunity to reach a wider audience, gain industry recognition, and develop their games on a major gaming platform. The partnership also offers access to Nintendo's resources, expertise, and support, which will be invaluable in helping Segagenesis to achieve their game development goals.
