> It's possible that you own a revision of a game that was previously unknown, or maybe you just have a really obscure game card.
This isn't as common as it was in older consoles, thankfully. And we have groups of cool people working in the background to preserve perfect dumps of basically any game they can get their hands on.
For me, it's still fun regardless, and removes a lot of friction for knowing where to get games: from my own legit copies of said games! (for as frequently as sites/archives go down that host pirated copies... it's honestly worthwhile doing it myself)
I've dumped all my NES cartridges and even though they match with existing No-Intro entries, it's still fun and gives peace of mind enough that I'm not unknowingly holding onto a rare revision.
Yeah, I'm not arguing against that. I don't dump my games often but it's still good to have that freedom, makes me feel like I actually own the product I bought for once.
