Square Enix has confirmed the main differences between Dragon Quest I & II versions for Nintendo Switch and Nintendo Switch 2. Forwards, the HD-2D remake will offer the same narrative experience on all platforms, but brings technical and compatibility changes that deserve attention.
In addition, the company has announced how the Save bonuses linked to Dragon Quest III HD-2D remake will work, ensuring rewards even for those who change console. Next, understand the main details and what to expect from each version.

What changes in Dragon Quest I & II in Switch and Switch 2 versions
According to official information, the main difference is in the compatibility between the platforms. The Dragon Quest I& II version for Switch 2 will be exclusive to the new console, while the switch edition will be compatible with both devices.
Therefore, anyone who purchases the switch editing can also play on Switch 2. However, the opposite does not apply. The version developed specifically for Switch 2 does not run on the previous console, whether physical or digitally. This detail directly impacts players who want to migrate from platform in the coming months.
In addition, graphic performance varies between the two versions. The Switch 2 version has an enhanced rendering, taking advantage of the upper processing power of the new hardware. Still, the content of the game remains identical: the story, the characters, and the available items are the same in all versions.

Save data cannot be transferred between versions
Another important point concerns rescue data. Square Enix has clarified that it will not be possible to transfer saves between the switch version and Switch 2. This is true for those who want to start on the switch and migrate later, and for those who think of playing alternately on both consoles.
The system recognizes each version as separate software. Therefore, even if the player gets both editions, he will not be able to integrate the data and need to start from scratch when changing console.
Dragon Quest III HD-2D bonuses work in both versions
Despite the limitation of saves, there is good news for those who care about the bonuses offered by Dragon Quest III HD-2D Remake. According to Square Enix, the gifts linked to the previous game can be rescued regardless of the version chosen for Dragon Quest I & II.
This ensures that players who ended the third title in the Switch version, for example, will still be able to receive the bonuses by purchasing the new remake on Switch 2. This flexibility offers an extra incentive for those who already follow the HD-2D trilogy.
Release and platforms confirmed
Dragon Quest I& II remake in HD-2D officially arrives on October 30, 2025 for Nintendo Switch, Nintendo Switch 2, PlayStation 5, Xbox Series X | S and PC (Steam). Steam's version will have a day late, on October 31st.
Square Enix stresses that all editions will maintain the same narrative and game structure, concentrating differences only in the performance and compatibility between platforms.
