Nintendo Switch Update 20.2.0 Fixes Child Safety Bug and Boosts Compatibility

Nintendo has released a new firmware update for Switch 2 and the original Switch. Version 20.2.0 fixes problems with the transfer of child safety settings and also improves downwards compatibility and system stability.

Child protection and network problems

Nintendo provides a new firmware update for the Nintendo Switch 2 and the original Switch including lite and OLED model for download. Version 20.2.0 brings important improvements to both generations of console and fixes specific problems that users have impaired since the launch of Switch 2 in June. According to the official message, the update for the Nintendo Switch 2 addresses a problem in which the child safety settings were not kept correctly during the system transmission. The update also contains general improvements.

A problem was also resolved for users of both consoles, in which one could not continue beyond “networks” in the Internet settings under system settings. Here, too, the usual stability improvements that Nintendo do not continue can take effect. Patch Notes: firmware update 20.2.0

• A problem was fixed in which the child security settings were not transferred from Nintendo Switch to Nintendo Switch 2 under certain circumstances during a system transmission.
• A problem was fixed in which one could not get out of “searching for networking” in the Internet settings under the system settings. [Nur Switch 2]
• General improvements in system stability to optimize user experience.

Reverse compatibility improved again

The most important innovation, which is not explicitly mentioned in the official patch notes, concerns the downward compatibility of the Nintendo Switch 2 with games of the original version. The well-known Nintendo-Dataminer “Oatmaldome” has examined the update as usual and confirms that you “fix some problems with the Switch 1 back compatibility again”. Particularly noteworthy: The game Portal 2, which previously crashed on the Switch 2, runs without problems after the update.

Oatmaldome encourages Switch 2 owners, games with whom they had previously had problems trying to try again after the update. This development follows the firmware update 20.1.5 of June 18, 2025, which also aimed at improving the reverse compatibility. At that time progress was made, but many titles continued to have problems.

Hopefully Nintendo now seems to have overcome these hurdles with the current update. Good to know: The Switch 2 is downwards with both physical and digital switch games. Some games are not directly compatible due to hardware changes in Switch 2 and the Joy-Con 2-controllers, but may be played with the joy-condes of the original version.

For most other switch games, the console uses a kind of emulation that enables switch games on switch 2 with new features such as gamechat support.
