@notsobigkid I have one for you.

Arcade Legends Ultimate. You know, the arcade console that has like 300 games on it...

The new one comes with an update that blocks a bunch of homebrew, that the older consoles were purchased specifically for

This firmware isn't available for the older consoles

but if you factory reset the new console, then rename the old console firmware, you get the old console firmware.

But you gotta factory first. And then when you do updates, it never updates as high as it came. Which... actually... Good. Stuff still works this way. lol
