Nice, just bought it.

In England, on the used game store CeX it's already sold out... What a surprise.

I checked both CeX and also GAME UK - they're all sold out. It's also now impossible to find physical cartridges on eBay, too.

It's on a well known website, I can tell you by pm, but not publicly in case scalpers go for it. Just leave it for folks to buy one if they want.

Are you sure about that? I took a second to search and found at least 1 DE and GB listing and many US listings.

Already bought a copy on eBay right after they all sold out. It is the standard physical version as I checked, there doesn't seem to be any sign that a digital NS1 release existed in physical form at least.

So really as long as a board with RP2350 OR a RP2040 we’re good then? Wasn’t sure if we needed both. Found a usb c variant on amazon

As far as I know, any development board that can run Pico firmware should do (including Pico clones), although by extension I'd imagine that any board using either RP microcontroller with an integrated USB port could work just as well.

such a shitty game (that ruined the franchise) and it's going to be super popular now. oh man nintapple are truly fucked now

Because what happens every time an exploitable game is revealed is that everybody rushes to buy it either to use it or to scalp it, resulting in the price going way up

Still my pride and joy.

I remember those PS5 games.

If I get Civ VII on a game card and never allow a switch to update it, will it always serve as a userland entrypoint? I guess the overflow can't be patched out of the game without an update... so even in the future, should I decide to update to a newer firmware and then some exploit lands, this game will be a good entry method, right?

Darth Meteos · Sunday at 8:57 PM

should we really be burning entrypoints like this?
i feel like we should really keep one of these private to have game dumps and console research moving forward...?

AFAIK there is no "overflow" or exploit beyond running arbitrary JS code in userland (nobody chimed in saying otherwise and I couldn't find evidence of it myself).

If you update to newer firmware, attack surface would decrease drastically, you would almost certainly be unable to use the fs exploit like what was chained with SmileBASIC entry point and would have to wait for new ones.

The game has arbitrary JS execution on first version which can be had by using the game card. It sounds to me the game would remain a viable entry point as Nintendo can't force you to update a card if you don't connect online in the first place. If I understood correctly.

Sorry I was sloppy with my question. I have no idea what kind of entrypoint it is, but it is definitely something that allows the input of an exploit (that's what the pico is doing).
I do have Seedsow on my Switch but somehow I feel like having a card that is physically in my hands and which can be used to inject whatever needs injecting is somehow more future-proof.

Would a Pi Zero W or a Pi 4b work? I currently use the former to inject keystrokes, either individually or from a block of text from my laptop via TinyPilot to the Switch 2, mainly for SmileBasic.

Yes, it is effectively the same dev board with the same microcontroller and it will work. W is for the wireless module which you don't need. H is for pre-soldered headers. Any variants will work just as well.

Thanks i bought it and the game paid 20 euro for the micro controller and 40 for the game.

I have a few questions regarding the exploit.
- I've seen some mention future hack might be permanent? is this that?
- Will we be able to play future games possibly with this method, or does this mean keep this switch at that 23.0.1 firmware forever?
- Is lower firmware also acceptable? i bought a new switch, keep it at that firmware?

To my knowledge physical game carts don’t ever get updated via the internet. The update is just stored on the console

Yes. Some older firmware is confirmed to work.

Tested at Switch 1 fw 22.5.0, Switch 2 fw 20.4.0 and 23.0.1 using pi pico 2 (RP2350)

And.... I grabbed the last 1 at my local Walmart for $12. Went to Gamestop 1st and they didn't have it for the Switch.
Ended up just preording Ocarina Remake since I was there.

To everyone buying the game now, double check that you realy get the physical copy.
There are reprints of the game, that only have a code in the box.

So there's a good chance the listing on Amazon sold by Deals Tavern is a code in the box?
