Switch 2 Backwards Compatibility Page Launches on JP Website, Lists Compatible and Games w/ Issues

mv5gbs0.png
 
I don't see Deadly Premonition Origins on either list, so I'm hopeful that with the Switch 2's higher specs, it can run it in backwards compatible mode without fps or crashing issues. It'd be sick to finally have a fairly stable version of the game lol.
 
So to recap, one game isn't fully compatible. A hundred and forty or so games they tested didn't work, and they're working with those developers to release patches. Fifty games work but have unexpected behaviors, so they're also working to get them patched. Another 10 games require you to pair Switch 1 joycons to the Switch 2 in order to play them.
 
Here are the games with issues from my own library. Grid Autosport is probably the only one I still play on Switch. Play the others mostly on steam.

Broken:
Darksiders Genesis
DOOM ® Eternal,
GRID ® Autosport
Wolfenstein ® II: The New Colossus™

Some issues:
Alien: Isolation
Street Fighter 30th Anniversary Collection International
Saints Row IV Re-Elected
 
But Switch 2 Support Joy-Con as controllers? That would be good for Mario Kart or Mario Party sessions with lots of friends.
 
At least all games that I have are compatible - but what about the performances? Upscaling would be nice, but I want some fps bump or at least stability.

Xenoblade games work, Metroid remastered works. Zelda totk gets upgrade.

I'm set. That's all I wanted to play on my SW2 from SW1 library I've held off on.
 
Told you all tegra chipset was a dead end. Switch 2 will have to pay the technical debt, but I guess anyone who buys a switch 2 is willing to pay for anything.

So our switch libraries won't transfer over to switch 2? That's insane to me. Zero chance of a day 1 purchase. Maybe in a few years. Nothing they announced looked great, and the fact my library may or may not work on Switch 2 is a huge letdown.

Do you even bother to read or just make any statement you think of?

It does transfer over. It's like PS4 to PS5 backwards compatability.
 
Switch 2 already confusing the fuck out of me with compatibility issues and pre orders.
What was that about them wanting to make the transition from Switch to Switch 2 as simple/seamless as possible?
Paying out of my ass hole for all of this too.
More questions than answers.

Ouch, Undernauts: Labyrinth of Yomi and Saviors of Sapphire Wings / Stranger of Sword City Revisited not working correctly, gotta fix those dungeon crawlers. And hopefully they also patch Nights of Azure 2, that first boss whale keeps killing me every time I boot the game, I already spent more time stuck in the first stage than time I spent finishing other games.

This is just weird. These games or Tokyo Xanadu don't do anything special.

Edit: There are a few other games that I have which have issues like Taito Milestones and Neverwinter (and a few more). Let's see what happens, but it's kind of puzzling.

Seriously? That sucks, I have a Japanese version and love this game for a while. I mean I also have it on Steam Deck and that's where I mostly play it. It's still annoying.

Hopefully they'll release a patch so it can work correctly on the Switch 2 hardware. I've now double checked the list and looks like the other title I have in my physical game collection that's impacted is Harvestella, but this one is in the 2nd category of BC games with issues.

Also, just seen this article from Automaton West with more details on the Switch 2 backward compatibility :

Nintendo is testing Switch 2 compatibility for Switch games "one by one," 25% of games run without issue so far - AUTOMATON WEST

Only 25% of Nintendo Switch games currently run without issue on the Switch 2 due to Nintendo implementing new technology for the console.
automaton-media.com automaton-media.com

According to an interview published on Nintendo's official website, the reason why older Nintendo consoles such as the 3DS and the DS, or the Wii U and the Wii, had full backward compatibility is because of how they were made – the DS hardware was implemented into the 3DS and the Wii hardware was implemented into the Wii U.

However, this isn't the case for the Switch 2, as it is not equipped with its predecessor's hardware. For the Switch 2, the focus was on enhancing its performance, which meant that its compatibility with the Switch was a lower priority for the developers. The approach to hardware design was vastly different from Nintendo's previous game systems, which is why it was difficult to achieve the same level of backward compatibility as the 3DS or the Wii U.

Therefore, a new technology is being used to run Switch games on the Switch 2. If something like a software emulator were to be used for the Switch 2, it would have to be run at full capacity and its battery wouldn't last long, which is why Nintendo implemented a new technology that they describe as a mix between a software emulator and hardware compatibility. According to them, the process of converting game data for Switch to run on Switch 2 is being performed on a real-time basis as the data is loaded. Due to the introduction of this new technology, each of the 15,000 Switch games is being checked for possible compatibility issues one by one – from whether they boot up, to the gameplay itself.

That doesn't bode well for full compatibility it seems. Basically, don't rush to sell your Switch 1.

Sounds like OG PS3 and PS2 BC. Presumably there is some emulation going on here?

Because the T239 is a different chipset, it's been confirmed that Switch 1 games run under a software compatibility layer. The cool news is that this means things like GameChat will work with Switch 1 games.
 
We need a tech version of Pimp My Ride. Imagine a show where they take your old console, fix all the quirks, boost the specs, and deck it out with custom mods that allow running switch 2 games. I'd buy the hell out of the original switch with switch 2 specs. No compatibility issues just a next gen feel.

Something tells me Nintendo hasn't tested every game released on the platform. That "15k" part feels like marketing hype.

They probably have an automated test process. For more important games they will also add manual testing on top.
