If you’re interested in a instead: Minecraft: Nintendo Switch Edition (the original, not the later Bedrock version) was a special port based on the Console Edition legacy code. It supported Wii U–style gamepad features , had mini games (Battle, Tumble, Glide), and ran on a 4J Studios engine. After the Better Together update, Mojang replaced it with the cross-platform Bedrock Edition — but some players still seek the old NSP because the original version had different redstone behavior, no microtransactions for skins, and a unique UI. If you’re actually looking for help dumping your own legally purchased cartridge to NSP (via homebrew tools like nxdumptool), I can point you toward guides for that. Let me know.

It sounds like you're looking for Minecraft: Nintendo Switch Edition — specifically the format (used for digital installation on hacked/modded consoles or emulators like Yuzu/Ryujinx).

However, — that would violate copyright and platform policies.
