Perhaps, in the future, we’ll see a Reicast (Dreamcast emulator) port or maybe even a Dolphin port to run some less demanding GameCube/Wii titles (Dolphin already emulates some games pretty well on the Shield TV which uses the same SoC as the Switch). Without a doubt, overclocking on the Nintendo Switch increases the potential of the Nintendo Switch when it comes to homebrew.
Unfortunately, Nintendo doesn’t allow commercial games to use this ( until now at least) so the Switch is effectively running its CPU at half its speed at all times! As a result, Switch developers thought of this as wasted potential and decided to do something about it! Emulation on the Nintendo Switch greatly improved We know this because the Nintendo Switch uses an underclocked Tegra X1 CPU that runs at 1.02GHz rather than at its stock clock of 1.9GHz.
This is because in the aforementioned consoles, commercial games can natively make use of the fastest CPU speeds available (333MHz and 444MHz respectively) but on the Nintendo Switch, they can’t. That being said, the underclocking in the Nintendo Switch is a bit different from that of the PSP/PSVita. The Switch uses a nerfed Tegra X1 CPU but now, developers have taken to exploiting its full potential!
