What is an ML1 file

ML1 files mostly belong to DeSmuME. ML1 files are used as an Nintendo DS ROM image file. They hold the complete binary data from a DS game cartridge.
When loaded into an emulator like DeSmuME, the file simulates the DS hardware on a PC.
Key details summarized by FilExt.com:
  • Contain full game data including code, graphics, and sound
  • Used to emulate Nintendo DS games
  • Require a compatible emulator to run correctly
  • FilExt.com tip: This format specifically mirrors the structure of a DS cartridge, making it integral for game emulation.

    How can I open an ML1 file?
