How to Download and Use BIOS Files for Nintendo DS Emulators

If you want to play Nintendo DS games on your PC or mobile device, you will need an emulator that can run them. However, some emulators also require BIOS files to emulate the hardware of the original console. BIOS files are binary files that contain the basic input/output system of the device, such as booting, memory access, and hardware configuration. In this article, we will show you how to download and use BIOS files for Nintendo DS emulators.

What are bios7.bin and bios9.bin?

The Nintendo DS has two processors: an ARM7 and an ARM9. Each processor has its own BIOS file that contains the code and data needed to initialize and operate the system. The bios7.bin file is the BIOS file for the ARM7 processor, while the bios9.bin file is the BIOS file for the ARM9 processor. These files are essential for emulating the Nintendo DS hardware and running games correctly.

What is firmware.bin?

The firmware.bin file is another binary file that contains the firmware of the Nintendo DS. The firmware is a software program that controls the basic functions of the device, such as the user interface, settings, clock, and touch screen calibration. The firmware.bin file is also important for emulating the Nintendo DS features and compatibility with some games.

Where can I download bios7.bin, bios9.bin, and firmware.bin?

Since BIOS and firmware files are copyrighted by Nintendo, they are not legally distributed online. However, you can dump them from your own Nintendo DS console using a flashcart or a homebrew application. Alternatively, you can search for them on the internet, but be aware of the legal and ethical implications of doing so.

One possible source for downloading bios7.bin, bios9.bin, and firmware.bin is [the Internet Archive], where you can find a 7z archive file that contains these files along with other files for melonDS emulator. You can download this file and extract it using a tool like 7-Zip or WinRAR. Another possible source is [Reddit], where you can find links to Google Drive folders that contain these files separately or together.

How to use bios7.bin, bios9.bin, and firmware.bin?

Once you have downloaded and extracted bios7.bin, bios9.bin, and firmware.bin, you need to place them in the appropriate folder for your emulator. Different emulators may have different folder structures and names, so you need to check the documentation or settings of your emulator to find out where to put these files. For example, if you are using melonDS emulator, you need to create a folder named "BIOS" in the same directory as melonDS.exe and copy these files there. You can also change the path of these files in the Config > Emu settings menu of melonDS.

After placing these files in the correct folder, you should be able to run Nintendo DS games on your emulator without any problems. However, some games may require additional files or settings to work properly. For example, some games may need a NAND file or a save type to be specified. You can find more information about these issues on [the Libretro Docs] or other online sources.


In this article, we have explained what bios7.bin, bios9.bin, and firmware.bin are, where to download them, and how to use them for Nintendo DS emulators. We hope this article has been helpful for you and that you enjoy playing Nintendo DS games on your PC or mobile device.
