First, it is critical to distinguish between the two formats. The format, developed by Igor Pavlov for the 7-Zip archiving utility, uses high-ratio compression to bundle multiple files—often a game’s data, save files, and metadata—into a single, smaller package. Its primary purpose is efficiency: saving bandwidth during downloads and storage space on hard drives. In contrast, an NDS file (Nintendo DS ROM) is a raw, uncompressed binary image of a Nintendo DS game cartridge. It contains executable code, graphics, sound, and game logic structured specifically for the DS hardware or an emulator. An NDS file is already in its final, usable state. Therefore, converting a 7z to NDS is not a transformation of data type but a liberation of the NDS file from its compressed container.
No. Changing the name of a file from game.7z to game.nds does not change its internal structure. Your emulator will try to read it as a game cartridge, realize it is looking at an archive wrapper, and throw a "corrupted file" error. Always extract, never rename. Summary Checklist
