Nintendo’s physical game releases could face another challenge as Macronix, one of the major manufacturers supplying memory chips for Switch and Switch 2 game cards, gradually withdraws from the ROM business. The Taiwanese semiconductor manufacturer is shifting its attention toward other memory technologies, leaving questions about what this could mean for the future of traditional Nintendo cartridges.
The development was highlighted by MST Financial senior analyst David Gibson, who reported that Macronix is phasing out its ROM manufacturing operations and will no longer develop new ROM products. The company’s third-quarter 2026 results help explain the decision, with ROM products accounting for just 5% of its revenue, down considerably from 26% during the same period last year. Sales from the segment also declined 39% year over year.
Macronix is instead prioritizing other memory technologies, including NOR and eMMC, as it redirects its manufacturing capacity toward areas with stronger demand. The company’s chairman, Miin Wu, has reportedly pointed to limited production capacity as a factor behind the decision. With ROM becoming a much smaller part of its business, continuing to invest in that segment appears to have become less attractive.
For Nintendo, the news is particularly noteworthy because Macronix has been an established supplier of memory chips used in physical game cards across multiple generations of hardware. However, its withdrawal does not mean that Nintendo Switch or Switch 2 cartridges are about to disappear. Macronix is not the only manufacturer supplying the components, and other companies, including ROHM, have also been associated with Nintendo’s game card production.
That distinction is important, especially with physical releases continuing to play a significant role in Nintendo’s business. Nevertheless, losing a major supplier could introduce additional pressure into an already complicated manufacturing landscape, particularly if alternative production capacity cannot easily accommodate demand.
There is also the question of how this could affect the growing presence of Game-Key Cards on Switch 2. Unlike traditional cartridges, these cards do not contain the complete game and instead allow players to download the required software. Although they retain a physical presence on store shelves, they offer a considerably different proposition for players who prefer owning games on their cartridges rather than relying on downloads.
Nintendo’s digital sales have also continued to grow. Digital purchases accounted for 61.5% of the company’s software sales during the April to June 2026 quarter, compared with 59.3% during the same period a year earlier. While physical games remain an important part of Nintendo’s business, the increasing popularity of digital purchases provides another reason for publishers to reconsider how they distribute their releases.
Macronix’s decision does not establish that Nintendo will abandon traditional game cartridges, nor has Nintendo announced any corresponding change to its physical release strategy. However, the development adds another complication for a format already facing questions about manufacturing costs, storage requirements and the growing reliance on Game-Key Cards.
For collectors and players who prefer having complete games on physical media, the bigger concern may not be whether Nintendo cartridges disappear overnight, but whether they gradually become harder and more expensive to produce. With alternative suppliers still available, traditional cartridges are unlikely to vanish immediately, but Macronix’s withdrawal is another reminder that the future of physical Nintendo games is becoming increasingly complicated.
