Seedsow Lua Editor: a Lua editor that runs inside the Seedsow Lullaby demo on Switch 1 and Switch 2
On Oct 26, 2026, developer DialingSpoon527 published Seedsow Lua Editor (version 0.1.2) on GitHub: a Lua editor that runs inside the Seedsow Lullaby demo, a game that uses Artemis Engine, on Switch 1 and Switch 2. It can be used with a controller and an on-screen keyboard or with a wired USB keyboard, and it also edits text and hex files in the game's own save storage. According to the author's README, the Switch 2 does not need to be modified or use SmileBASIC 4; the editor reaches the Switch 2 through Nintendo's official save transfer, from an already modified Switch 1. The author says they tested the US eShop demo on both consoles.

Context
This runs inside a game (user level): it is not kernel access, not CFW, and there is no backup loader. The author warns that the project is "vibecoded" (made with AI help), may have rough edges, and has not confirmed a route to a broader exploit through Artemis. Nintendo may block save transfers, and then the method stops working. The author also warns that using modifications on a Switch 1 connected to Nintendo is not ban-proof. Earlier, __alula and Gezine had already talked about Artemis Engine games; see the earlier notes on this site. All of this is still research and proof of concept. This site does not publish step-by-step guides or download links.
