Fucking Limited Run Games strikes again. This time they stole mGBA! Time to break out this classic from @foone again...
Actually it looks like the publisher was WayForward. They might have licensed the emulator from LRG though? I'm not really clear. Sigma Star Saga DX.
Ok clarification time. The game was published by WayForward but they just licensed the Carbon Engine from Limited Run Games. LRG, however, integrated mGBA, presumably without disclosing it to WF, so WF is transitively violating the license. I don't blame them per se, but LRG is 100% absolutely in the wrong here. The game in question is Sigma Star Saga DX, and I have confirmed it uses mGBA by now.
There appears to be a third company in the mix that was the "developer" (Mighty Rabbit Games) so it could be a case of them messing this up in the process. I'm not really sure who did what at this point. Their website is down and has been for some time so uh, wouldn't shock me if they're just incompetent.
@endrift They are on linkedin (shudders), and there's a linktree link from their facebook (double shudders): https://linktr.ee/mightyrabbitstudios. I think this is the same company you're talking about, their website has a database error.

Linktree. Make your link do more.

@maaneeack it was pointed out to me that it was a spinoff of LRG from the original founder, so yeah I get to blame that executive anyway

@endrift Classic corpos stealing from the internet and not getting punished.

It's hard not getting jaded by this kind of shit.

@endrift do you want me to gift you the game on Steam so you can check?
@voltagex I ended up buying it and refunding it immediately upon discovering whether or not it used mGBA (it does. it straight up has the github URL in the file)
@endrift RIP. I would have expected better from WayForward but maybe I am naive.

@endrift God, again? I'm curious if the credits say anything. I remember LRG's handling of Tomba was pretty awkward - their GPL acknowledgment just listed the name of the emulator, no source release or even what commit they built from.

I wonder what the relationship is to LRG. This was originally announced as an LRG release but the current version lists Mighty Rabbit, which is a company founded by LRG's founder (who's since left LRG).

@misty They do not. WayForward licensed the Carbon Engine from LRG, and I'm guessing LRG just did not disclose this to WF. God I hate LRG.
@endrift Yuck. I'm curious if they disclosed it or not in the previous Carbon Engine GBA releases.
@misty @endrift I don't know the MPL very well. What's required to come to compliance? Publish Carbon Engine source? Surely bundling an emulator is just what the GPL calls "mere aggregation"?

@JordiGH I believe they wouldn't have to publish the whole engine - a MPL library doesn't infect the whole codebase it's used in.

I was able to make Goodboy PC version comply by publishing (under MPL) the source code for my modifications to mGBA, and providing a link to those on the game's licenses screen.

In some ways it was easier than even MIT, as I didn't have to reproduce the full license text. The full acknowledgement looked like this:
