If I were to speculate, they are waiting for the NVK (Open source NVIDIA driver) to be more mature. So, they wouldn’t have to release two versions and wouldn’t depend on NVIDIA to update their driver to work with software the Steam Deck uses. I.E. Steam Deck uses gamescope for everything outside of Desktop mode. NVIDIA’s driver didn’t work with it until 2 months after the Steam Deck release. Even though it had existed for years prior.

Do we know that for certain? Maybe they have the DNA but it isn’t the resulting phenotype. I.E. There is nothing preventing two brunettes from having redheaded children.

This doesn’t contain the game code either. It takes a user-supplied ROM and converts it to an executable. Nintendo do not own the code that performs the conversion.

Do you have a work profile or multiple user profiles set up on your device? This is similar to another issues they had a couple months ago, where my phone would fail to boot even into recovery to try to factory reset it.
