They don't have it. It's a limited liability company so in this way they will pay only the sum of their assets (=bankruptcy) which is lower than legal expenses against a Goliath and definitely lower than 2.4 million. I'm guessing 1000x lower than the settled amount or they wouldn't have reason to found the LLC in first place or to settle this easy and this fast
My understanding is they've been making 30k a month from their Patreon.
Which is also the main reason they were vulnerable to a lawsuit, because they've been profiting off of the emulator (which why legal by itself, is only popular enough to make money due to piracy).
$2.4M is 8 years' worth in that case, assuming they were making that much the entire time. And of course a lot of that money was probably for the devs to afford basic living expenses.
