Desktop running Windows aka Desktop used for piracy..

What's the difference? People can use any of their devices at home for piracy.

TBH, I want legit content for my (previous model). I have a few of the new homebrew console titles on it, and stuffed it with a few PS1 discs I owned (these can be imaged on a modern PC optical drive).

I seriously considered getting a tool to dump the actual legit cartridges I own to populate the unit, but they're surprisingly pricey (I think like 50USD+ last I checked), and it felt like the sort of thing that you'd get a lot of questions about if Customs opened the package. So it largely sits in a drawer waiting for me to play the FF5 PS1 adaptation.

You call it piracy

I call it the freedom to run arbitrary code.

It might be technically piracy, but who's really losing out on lost sales if I buy this and play SNES on it?
