It was only days from the jailbreak, to dumping games, to these Eden emulator forks. You're right about the length of the console lifecycle, but the context is a little different.

Well, it was hard enough because it still needed some work and about 18 months to get to a crappy build but yeah

Note how it took months of no progress then mere weeks after the first jailbreak was released. The jailbreak is the innovation here, the emulator itself barely changed to accommodate the Switch 2, relative to the initial work of building the Switch 1 version.
