Switch 1 vs Switch 2: Macronix ROM Exit and the Cartridges Question
Macronix’s decision to exit ROM production for game cartridges shines a light on the supply chain behind Nintendo’s physical games. The news centers on how much of that supply is affected, whether Switch 1, Switch 2, or both are exposed, and what it could mean for cartridge pricing, Game-Key Cards, and the future of boxed games.
Macronix’s announced exit from ROM and what it means
Macronix, a long‑time supplier of ROM memory used in Nintendo’s physical cartridges, announced that it is phasing out ROM products by the end of the third quarter of Macronix’s fiscal year 2026 and will reallocate capacity toward NOR and eMMC memory chips. The company will stop reporting ROM sales as a separate line in future financial releases. This is a planned phase‑out, not an abrupt cutoff, which gives Nintendo and publishers time to adapt and seek second sources.
In practical terms, the disruption is framed as a shift in where Macronix directs its manufacturing capacity rather than an immediate shutdown of supply. Coverage from industry observers notes that Nintendo will have other partners to draw on for cartridge production, but the timing and breadth of any impact depend on how quickly Macronix’s transition unfolds and how much spare capacity remains with other suppliers.
The numbers and what they signal about impact
From Macronix’s own reporting, ROM products accounted for 5% of its Q3 2026 revenue, a decline of 39% year over year. The smaller share matters for Macronix, but it becomes critical for Nintendo and game publishers, who rely on cartridge memory for physical releases. The broader implication is that Macronix can lose the ROM line with only a modest overall revenue impact on its business, while Nintendo’s cartridge memory needs remain substantial and must be met by other sources.
For readers tracking the consumer side, Nintendo’s digital sales discussion is revealing. In the period covered, digital sales accounted for more than 60% of Nintendo’s total software sales in Q4 2026 and Q1 2027, though this figure fluctuates with major game releases. The precise figure cited elsewhere is 61.5% for April–June, with a yearly range reported as 46.1% to 67.2% over the past year. This volatility matters because it helps frame how much price pressure or shift toward Game-Key Cards might be expected if cartridge memory becomes tighter or more expensive.
What happens next: Switch 1 vs Switch 2 exposure
Reporting on who supplies Switch cartridges during the Switch 2 era is mixed. Some sources suggest Macronix supplies ROM for both Switch 1 and Switch 2, while others attribute Switch 2 cartridge memory primarily to Rohm Semiconductor. The confirmed record does not settle this point, so readers should treat Switch 2 exposure as disputed at this time. The broader takeaway is that Switch 1 cartridges appear more exposed to Macronix’s exit, while Switch 2 exposure may hinge more on Rohm’s capacity and contracts.
It’s also important to recognize that Switch 2 began selling in 2025, and its physical catalog is still evolving. Even if Switch 1 is more affected, Nintendo’s multiple suppliers and ongoing new releases mean the impact on overall physical availability is unlikely to be immediate or total.
Who else makes Nintendo’s cartridge components?
Macronix isn’t Nintendo’s only supplier. Rohm Co., via its Oki Semiconductor unit, is identified as another cartridge memory supplier. A multi‑source setup cushions the supply chain against a single vendor exiting, though it does transfer some bargaining power and potential cost pressure to the remaining suppliers. Nintendo buys memory at a scale that gives it leverage, but a shrinking supplier pool can influence unit costs over time.
How Game‑Key Cards work and why they’re central to the conversation
A Game‑Key Card is a physical card that contains a download key rather than the full game data. To play, the user must download the game, so the card itself is not a self‑contained copy of the software. This design reduces the cartridge’s data footprint and is often discussed as a response to memory costs or supply constraints.
| Aspect | Standard game card | Game‑Key Card | Notes |
|---|---|---|---|
| What the cartridge holds | The complete game data | A download key | Game is downloaded after purchase |
| Internet needed | No download required | Yes, a download required | Crucial for initial access |
| ROM‑class memory dependency | High | Low | Key data only on cartridge |
| Console storage use | Minimal beyond updates | Depends on installed copy | Storage cost shifts to the console or microSD |
| Works offline after install | Yes | Depends on the downloaded copy | Reliance on servers if not installed locally |
As a reader, you should know that the choice between standard cards and Game‑Key Cards affects ownership and risk. A standard card is a self‑contained copy; a Game‑Key Card licenses the game through a download and can be vulnerable to changes in online services or storage availability. For readers planning future purchases, this distinction helps set expectations about long‑term access and preservation.
Cartridge costs: what a Switch cartridge might cost to make
Publicly confirmed per‑unit production costs are not published by Nintendo or its suppliers. Reported estimates range from about $12 to $18 per unit, but those figures circulate as notes and analyses rather than official company numbers. The spread across three commonly cited estimates is as follows:
| Estimate | Lower bound | Upper bound | Midpoint | Status |
|---|---|---|---|---|
| A | $12 | $15 | $13.50 | Unconfirmed |
| B | $13 | $16 | $14.50 | Unconfirmed |
| C | $16 | $18 | $17.00 | Unconfirmed |
The overall spread of $6 between the lowest and highest estimates shows how little is publicly verifiable. Even a small change in per‑unit cost across a million cartridges translates into significant budget implications for publishers, so these figures are watched carefully, though none are official company figures.
What players and collectors should know now
Despite Macronix’s exit, there’s no call to panic. The supply disruption is being managed through alternative suppliers, and Nintendo remains committed to physical games. Readers should avoid assuming an immediate end to physical cartridges and instead focus on informed purchasing and preservation practices.
Practical steps include reading packaging to determine whether you’re buying a full‑data cartridge or a Game‑Key Card, budgeting for console or microSD storage for downloaded games, and watching Nintendo’s official announcements for any policy or pricing changes. If you want to keep games long‑term, prioritize full‑data cartridges when available and keep an eye on the official channels for format updates.
For context, the nine Nintendo releases planned for November provide an opportunity to verify formats before ordering, helping you avoid unwanted surprises in cartridge type.
Five predictions for cartridges and Game‑Key Cards
These are analytical projections grounded in the confirmed facts and typical supply‑chain behavior. They are not official Nintendo statements.
- Nintendo will line up replacement supply quietly. Rohm and other suppliers already support Nintendo, so volume can shift without a public announcement.
- Per‑card costs will rise modestly at most. A multi‑source market preserves Nintendo’s leverage, suggesting small changes rather than a shock.
- Small publishers will feel it first. Short print runs with tight margins may turn toward digital or Game‑Key Card formats to manage costs.
- The Game‑Key Card debate could intensify without an explicit Nintendo policy change. New key‑card releases might be blamed on supply constraints regardless of direct causation.
- Memory vendors will continue exiting low‑volume lines. Macronix won’t be the last supplier to shrink, so longer‑term contracts and diversification remain essential for system manufacturers.
What to watch next
Three signals will help clarify the picture. First, Nintendo’s own commentary about supply and physical strategy in upcoming earnings materials. Second, the mix of formats on new releases—if more third‑party titles ship as Game‑Key Cards, that would align with cost‑pressure hypotheses without proving them. Third, any capacity announcements from Rohm or other suppliers, which would indicate how the market is absorbing Macronix’s exit. Stay tuned to Nintendo’s official communications for definitive guidance.
FAQ: quick clarification on key points
Is Macronix really leaving the ROM business? Yes. Macronix plans to phase out ROM products by the end of the third quarter of Macronix’s fiscal year 2026 and will shift capacity toward NOR and eMMC memory.
Will Switch 2 games get more expensive? That remains unconfirmed. Reports discuss potential price increases, but no official price change has been announced, and Nintendo has other cartridge suppliers.
Does Macronix supply Switch 2 cartridges? Reports say Macronix ROM chips go into cartridges for both Switch and Switch 2, but there is at least one account disputing Switch 2’s involvement and crediting Rohm instead. Treat this point as unsettled.
What is a Game‑Key Card? A Game‑Key Card contains a download key rather than the complete game data. An internet connection is required to download the game.
Will Nintendo release more Game‑Key Cards because of this? This is unconfirmed. Nintendo has announced no policy change, and any link between Macronix’s exit and new key‑card releases remains speculative.
Who else makes Nintendo’s cartridge components? Rohm Co., including Oki Semiconductor, is identified as another supplier alongside Macronix.
Are physical Switch cartridges going away? There’s no confirmed record showing physical cartridges will disappear. The claim that they will vanish is unconfirmed.
How much does a Switch 2 cartridge cost to make? No official figure exists. Published estimates range from $12 to $18 per unit, and these come from secondary reports, not primary company disclosures.
Context on longevity: what we know about cartridge life and preservation
Switch cartridges rely on XtraROM, Macronix’s proprietary read‑only NAND flash. This technology supports durability and long data retention. Official specifications indicate data retention of at least 20 years under sustained 85°C; at room temperature, reliability is projected for 30–40+ years. To mitigate charge loss over time, preservationists advise occasionally energizing memory by inserting cartridges into a powered console every 5–10 years. These technical details help explain why physical cartridges can remain viable for decades, which is a factor many collectors weigh when considering long‑term ownership.
Historical and strategic context
Nintendo has long relied on cartridges, and the Switch era extended this approach into a hybrid handheld/console format. Memory cycles in the semiconductor industry are subject to boom‑and‑bust dynamics, and ROM is a niche within that cycle. Supplier exits are not new, but Macronix’s move in 2026 drew atypical attention because it intersects with the rise of Game‑Key Cards and a growing digital share in Nintendo’s software mix.
Closing takeaway
The Macronix exit is a supply‑side story with downstream implications for cartridge pricing, Game‑Key Card usage, and the relative appeal of physical versus digital purchases. The most robust takeaway is that Nintendo has access to other suppliers, and a measured transition is likely. The strongest evidence at this point supports: Macronix exiting ROM; ROM accounting for 5% of Macronix’s Q3 2026 revenue and a 39% YoY drop; Rohm as another supplier; and Game‑Key Cards remaining a potential option. The fears of a wholesale end to physical Switch cartridges are not yet substantiated by official statements.
