I have Pico 4 5.2.7, should I update?

So I want to use virtual desktop (I've paid for it) but mistakenly updated it on the Pico 4, now I can't launch it because it needs to be on a later firmware version and there's no older versions of virtual desktop to be found. I've got a bunch of games installed on my Pico 4 that I don't want to lose. I don't know how the piracy scene is for Pico 4 lately, afaik don't go past 5.4? What do I lose out by updating my headset?

Thanks
