It’s astonishing how little people here know about the legality of emulators.

It’s perfectly legal to charge money for one, that was settled over 20 years ago.

Yuzu died because their devs were sharing ROMs between them and developing it on unreleased games. Not because they charged for it.

This will not be pulled and Nintendo has no legal grounds to sue the dev.
 
nintendo should just release their own emulator and profit off old games
It’s legal to back up and emulate software you own. In fact it’s necessary these days, since companies sell games digitally and then shut down the storefronts (as Nintendo just did with the 3DS store). Of course Nintendo would love to just endlessly sell you remakes of their old games, but if you bought it once and backed it up, you can play it forever perfectly legally.

Sure, now you tell me exactly how you personally backed up your Nintendo 3DS games and created the roms. Go ahead and post your personal pictures of the hardware you used.

Now just admit you downloaded the roms off a website, claim you "own" them, and pretend like its completely legal to use someone else's ROM, not yours (because you don't even own a 3DS game), and rationalize it.

Ahh the internet.

He may have downloaded tons of games he already owns. I do this all the time as most of my PSP collection is imprisoned on the PSN. In the UK it is not illegal to use copies of software you have paid for.

Whilst not exactly legit it’s not illegal either. They own that game and can copy its code if they like. It’s kinda like asking a friend to make a cassette of a CD because your aunt brought you the wrong format and you only have a Walkman.
 
The eStore for Nintendo 3DS was shut down - there is now no way to purchase 3DS games through retail either physically or digitally.

Hence, why its status as an emulator likely meshes with Apples "retro" rule

You can buy 3DS games all day on eBay, Mercari etc. They did not suddenly disappear from existence.

Except I don’t need to demonstrate any of that, and emulating remains perfectly legal. 🤷‍♂️

For the record I owned at least two 3DS systems back in the day, along with every game I’d be interested in emulating. I also think Nintendo is greedy and scummy with their overpriced remakes and shutting down online stores. They can pound sand.
 
Well I tried this emulator and it's a bit meh, can't see it has a smaller joystick option, and the game I tried stuttered along. Can't see any options either in it? Delta certainly seems like a more polished as option.
 
So that means you can rightfully steal it?
Emulating software you purchased is not theft. Not sure how many times this has to be repeated. But OP’s point was not about theft. It was about whether or not retro emulation (of games no longer sold by Nintendo) would be a major priority for Nintendo’s lawyers. Either way, there’s nothing for them to go after here. Rom sites, yes; emulator software, no.

It wasn't just that, it was also the fact that they had guides explaining how to extract encryption keys on their site. Nintendo saw that as Yuzu actively participating in circumvention of copy protection, which is illegal under DMCA.

I'm honestly surprised they figured it out how to make it work without JIT.
A lot of emulators have two CPU modes: interpreted (essentially emulating the system's CPU) or dynamically recompiled (converts the system's CPU instructions to x86-64 or ARM instructions). They probably just implemented a build flag to remove the recompiler.


Bold of them to charge for it. Talk about walking on thin ice.
Selling open source derived code is allowed by practically all open source licenses. Most of them require you to change the name of derivative works to reduce confusion (plus the original name may be trademarked). Some licenses such as GPL let you sell open source software but require the developer of the paid software to provide the source code to anyone that asks for it.

Also, it's a misconception that open source software has to be free. "free software" means that it's free as in freedom, but not necessarily free as in cost. A developer of open source software can choose to charge money for it. The issue is that due to open-source being free, there's no way to prevent a paying user from giving the source code to someone else for free.
