Nintendo Switch Cartridges Still Taste Awful – And That’s Intentional

Nintendo is back with the second generation of its beloved console, the Switch 2, boasting new features, faster hardware, and a sleek design. Yet, one peculiar aspect from the original system remains intact: the cartridges still taste absolutely disgusting. But don’t worry—that’s on purpose.

Let’s break down what’s new with the Switch 2, why the gross-tasting cartridges persist, and what it tells us about Nintendo’s ongoing approach to safety and innovation.

Why Do Switch 2 Cartridges Taste So Bad?

Nintendo has confirmed that Switch 2 game cartridges are still coated with a bitter chemical compound to deter accidental ingestion by children or pets. According to Takuhiro Dohta, a lead developer at Nintendo, “We have indeed made it so that if it enters your mouth, you’ll spit it out.”

The original Switch used denatonium benzoate, one of the most bitter substances known to man, commonly used in anti-chewing agents for pets and children. Although it hasn’t been officially confirmed if the same coating is used on Switch 2 carts, the intent is the same—discouraging anyone from putting them in their mouth.

This strategy isn’t just smart; it’s proactive safety design. Though licking a cartridge won’t hurt you, the flavor will make you regret the attempt. Nintendo even went as far as to discourage people from testing it themselves. “I do not advise that you do,” said Dohta, and fellow developer Kouichi Kawamoto admitted, “I did lick it once, but never again.”

Key Highlights from the Switch 2 Cartridge System

Bad Taste, Same Purpose: Coating still designed to prevent swallowing.

– Possible Chemical: Likely denatonium benzoate, though unconfirmed.

No Harm Done: Tastes terrible, but causes no physical harm.

Nintendo’s emphasis on user safety and their evolving cartridge design continues to make the company a unique force in the gaming industry—balancing innovation, accessibility, and family-friendly focus.

What Undercode Say:

Nintendo’s decision to keep the foul-tasting coating is more than a quirky detail—it reflects the company’s dedication to thoughtful product safety. While competitors often rely on warning labels and parental settings, Nintendo integrates physical deterrents into its design language. That’s design thinking rooted in real-world behavior.

The move to faster cartridges and the introduction of Game-Key Cards signals a shift in how Nintendo wants users to experience physical media—less storage, more authentication. This could be a subtle pivot toward a hybrid model of digital-physical gaming, where the cart is merely a key and not the container.

This, however, introduces long-term concerns: if the cartridge holds no game data, it raises questions about ownership, game preservation, and accessibility in the future. Once servers go offline, will these keys be useless?

Another point worth analyzing is Nintendo’s pricing and release strategy. The Switch 2’s base price sits at a premium $450—$50 more than the original launch price of the first Switch. Factoring in the bundle price and delays due to tariffs, there’s a visible push toward a more premium ecosystem, suggesting Nintendo is betting big on its diehard fanbase.

It’s also curious how much buzz is created by something as trivial as a bitter-tasting cart. But that, too, is a masterstroke. It generates organic, viral marketing—a talking point that spreads across social media and builds hype in the most unconventional way.

This tongue-in-cheek detail masks a much larger trend: Nintendo is refining how it controls the player experience—both digitally and physically—down to the last detail. Whether it’s through chemical coatings or proprietary key-based carts, the company maintains full control over how its products are used and consumed.

That’s not just innovation. That’s vertical integration—Nintendo-style.
