A .7z file is a compressed archive (like a digital suitcase). It was created using 7-Zip software. Developers and scene release groups compress NDS ROMs into 7z files to save bandwidth and storage space. An NDS game that is 64 MB might compress down to 20 MB in 7z format. display a white screen

A common bad tip on forums is: "Just change the file extension from .7z to .nds."

Do not do this. Renaming a file does not convert the data. If you rename Mario.7z to Mario.nds, the file is still compressed chaos to the emulator. The emulator will either crash, display a white screen, or throw a fatal error. You must properly decompress the archive.
