[Unverified] first homebrew game made with the HBLauncher SDK

Fri, 23 Oct 2026 00:00:00 GMT

[Unverified]

Follow-up to the HBLauncher story. Reddit user u/FR0GG1D posted (r/switch2hacks) a short video of a Snake game running on Switch 2, made with the HBLauncher SDK. According to the author, SmileBASIC only loads a small starter program that lets a computer use the console's graphics chip (GPU); the game itself runs on the GPU and, once loaded, keeps running without the computer and without Wi-Fi. He says he will make another game.

Context: Nothing changed in the jailbreak status: it is still research / proof of concept on firmware 23.0.1, through ns2jb, with no access to the system core (kernel), no native apps and no CFW. Close the app and it's all gone. Reactions on Reddit were split: many found it minor and criticized the use of AI.

Scam alert: there is no 'CFW activator' for Switch 2

Fri, 23 Oct 2026 00:00:00 GMT

A GitHub project, shared on Oct 23 by the X account @Techjunkie_Aman, presents itself as a one-click 'CFW activator' for Switch 2 and claims firmware 18.0.1 support. The Switch 2 never had that version: Nintendo's official list starts at 20.x. There is no CFW for Switch 2. The only public jailbreak, ns2jb, is research / proof of concept, with no kernel access and no CFW. Any 'activator' promising CFW is a scam or may contain malware. Don't download or run it. For safety, we don't link or name the project.

The post doesn't say the project works; it only repeats its claims. We did not test the project and don't know whether it contains malware.

Gezine: Artemis Engine games don't work alone for exploits

Fri, 23 Oct 2026 00:00:00 GMT

Gezine (@gezine_dev) explained that an exploit save can't be transferred without Nintendo's online service (Nintendo Switch Online) and that an already modded Switch 1 would also be needed. So, according to him, Artemis Engine games can't be used to exploit without another existing exploit. He said people should only buy games for a save exploit if they really know what they are doing.

The developer's technical opinion; Nintendo has not commented.

HBLauncher and ftpd-sb: first homebrew apps on top of ns2jb

Fri, 23 Oct 2026 00:00:00 GMT

Update: Update (Oct 23, 3:16 PM BRT): user @Chona_Pardo posted on X a photo of ftpd-sb working with SmileBASIC 4 version 4.4.6, using a Mac as the helper computer. It is independent confirmation that the tool works. It is not a new release or a new version.

Developer @ravensclawx released HBLauncher + SDK (v0.2.0), a menu that opens small homebrew apps on Switch 2 through ns2jb in SmileBASIC 4, and ftpd-sb (v0.1.0), an FTP server that runs inside HBLauncher. According to the README, apps run on the console GPU and the SDK offers controller input, read-only NFC and networking (UDP). The README itself says it is NOT CFW, does not load NRO files and does not run native ARM64 apps. It only works on the same version as ns2jb (firmware 23.0.1) and is still tethered: it depends on a computer staying on the whole time and is gone after a reboot. ftpd-sb only reaches SmileBASIC's own files (save and tmp writable; romfs read-only), not the SD card or other games' saves.

Context: Risks stated by the author: the post warns the project was 'FULLY VIBE CODED' (made with AI) and that he is not responsible for what happens to the console. The README mentions risk of data loss and corrupted saves, and says FTP writes and deletes affect real files. Nobody has independently reviewed the code.

mac2jb: a Mac acts as a USB keyboard to start ns2jb on Switch 2

Fri, 23 Oct 2026 00:00:00 GMT

Developer @cpypwn released mac2jb v0.1.0 (MIT license). The tool makes an Apple Silicon Mac pretend to be a USB keyboard to start pepsipu's ns2jb on Switch 2. It uses USB emulation libraries by Shiny Quagsire. According to the author, it was tested on a single configuration only. It is experimental and relies on a third-party macOS driver; for the test, the author turned off Mac security protections and warns this lowers security. ns2jb itself is unchanged: tethered (gone after reboot), no kernel access, no CFW.

Context: Also on Oct 22, 2026: Alula (@__alula) said games made with the Artemis Engine can work as entry points, but only together with another vulnerable game, and stated Nintendo 'WILL block' save transfers. That is her view; Nintendo has announced nothing. Gezine (@gezine_dev) said he would not recommend buying Artemis Engine games because of the exploit, since save exploits are a bad choice if Nintendo blocks the online service.

Switch 2 gets its first software jailbreak: ns2jb

Thu, 22 Oct 2026 00:00:00 GMT

Researcher pepsipu (Sammy Hajhamid) showed ns2jb. It runs custom code on Switch 2 firmware 23.0.1. The demo added new characters to Mario Kart World. It uses bugs in the SmileBASIC 4 app and in the system's file module (fs). It is research / proof of concept: it doesn't work on the console alone, is gone after reboot and has no kernel access.

SmileBASIC 4 pulled from the eShop

Thu, 22 Oct 2026 00:00:00 GMT

Right after ns2jb, SmileBASIC 4 left the eShop (e.g. the UK page returns 404). Nintendo has not explained why.

The link to the exploit is press inference; Nintendo has not confirmed.

[Rumor / unconfirmed] Gezine says there is a physical-cartridge exploit

Thu, 22 Oct 2026 00:00:00 GMT

Gezine wrote that SmileBASIC 4 is 'not strictly needed' and that there is an exploit based on a physical game cartridge. He also said he thinks an untethered jailbreak is possible. None of this is released.

Gezine said he used a userland bug and an HDMI capture card to dump a game's code, to study PAC protection. Research, not a jailbreak.
