An emulator is a software that mimics the hardware and software of another device, allowing you to run its games and applications on your computer. To play Nintendo DS games on your PC, you need an emulator that can emulate the dual-screen, touch-screen, and microphone features of the handheld console. You also need some special files called BIOS, which are essential for booting up the emulator and running the games.
In this article, we will explain what are Bios7 Bin and Bios9 Bin files, where to get them legally and safely, how to use them with an emulator, and how to get and run Nintendo DS games on your PC. We will also share some tips and tricks for a better gaming experience. Let's get started!
What are Bios7 Bin and Bios9 Bin files and why do you need them?
Bios7 Bin and Bios9 Bin are two files that contain the firmware of the Nintendo DS console. Firmware is a type of software that controls the basic functions of a device, such as booting up, loading games, and communicating with other devices. The firmware of the Nintendo DS is divided into two parts: one for the ARM7 processor (Bios7) and one for the ARM9 processor (Bios9).
Why do you need these files to play Nintendo DS games on your PC? Because they are required by most emulators to emulate the hardware and software of the console. Without them, the emulator won't be able to boot up or run any games. Think of them as the keys that unlock the door to the Nintendo DS world.
However, these files are not freely available or distributable, as they are protected by Nintendo's intellectual property rights. This means that you can't legally download them from any website or share them with anyone else. The only legal way to get them is by dumping them from your own Nintendo DS console using a special device called a flashcart. A flashcart is a cartridge that can store data on a memory card, allowing you to run homebrew programs or backup games on your console.

Where to download them legally and safely
As we mentioned before, the only legal way to get Bios7 Bin and Bios9 Bin files is by dumping them from your own Nintendo DS console using a flashcart. This process requires some technical skills and equipment, so it might not be suitable for everyone. However, if you are interested in doing it, here are the steps you need to follow:
Get a flashcart that is compatible with your Nintendo DS model. There are many types of flashcarts available on the market, such as R4, Acekard, CycloDS, etc. Make sure you do some research before buying one, as some might not work with certain consoles or firmware versions.
Get a microSD card that can fit into your flashcart. The size of the card depends on how much data you want to store on it, but we - Continue writing the article. Format your microSD card to FAT32 using a computer. This will erase all the data on the card, so make sure you back up anything important before doing this.
Download the latest firmware for your flashcart from its official website. The firmware is the software that runs on the flashcart and allows it to function properly. Extract the firmware files and copy them to the root directory of your microSD card.
Download a homebrew program that can dump the BIOS files from your console. One example is NDS Backup Tool Wifi, which can transfer the files wirelessly to your computer. Extract the program files and copy them to a folder on your microSD card.
Insert the microSD card into your flashcart and insert the flashcart into your Nintendo DS console. Turn on the console and launch the flashcart menu. Navigate to the folder where you copied the homebrew program and run it.
Follow the instructions on the screen to dump the BIOS files from your console. The files will be named bios7.bin and bios9.bin, and they will be saved on your microSD card or sent to your computer, depending on the program you used.
Copy the BIOS files to a safe location on your computer and keep them for future use. Do not share them with anyone else or upload them online, as this would be illegal and unethical.
If you don't have a Nintendo DS console or a flashcart, or you don't want to go through the hassle of dumping the BIOS files yourself, you might be tempted to download them from some website or forum. However, we strongly advise against this, as it would be illegal and risky. You could face legal consequences from Nintendo or get infected by malware or viruses from untrusted sources. Therefore, we recommend that you only use BIOS files that you obtained legally from your own console.
How to verify their authenticity and integrity
Once you have obtained the BIOS files legally, you might want to verify their authenticity and integrity. This means checking that they are genuine and not corrupted or modified by someone else. This is important for ensuring that they work properly with your emulator and that they don't contain any malicious code or data.
One way to verify the authenticity and integrity of the BIOS files is by comparing their checksums with the ones from official sources. A checksum is a unique string of numbers and letters that is generated from a file using a mathematical algorithm. If two files have the same checksum, it means that they are identical in every bit. If they have different checksums, it means that they are different in some way.
To compare the checksums of your BIOS files, you need a tool that can calculate them and display them for you. One example is HashCalc, which is a free and easy-to-use program for Windows. Here are the steps you need to follow:
Download HashCalc from its official website and install it on your computer.
Run HashCalc and click on the "..." button next to the Data field. Browse to the location where you saved your BIOS files and select one of them.
Select SHA1 as the hash algorithm from the drop-down menu below the Data field.
Click on Calculate and wait for a few seconds. The checksum of your file will appear in the Result field.
Repeat steps 2-4 for the other BIOS file.
Compare the checksums of your BIOS files with the ones from official sources. You can find them online by searching for "nds bios checksums" or "nds bios hashes". One example is this page, which lists - Continue writing the article. the checksums of the official BIOS files from Nintendo. If your checksums match the ones from official sources, it means that your BIOS files are authentic and intact. If they don't match, it means that your BIOS files are corrupted or tampered with, and you should get new ones from your console.
Another way to verify the authenticity and integrity of the BIOS files is by using a tool that can compare them with the ones from a database of known good files. One example is No-Intro, which is a project that collects and verifies ROMs and BIOS files for various consoles and systems. Here are the steps you need to follow:
Download No-Intro's Nintendo DS dat file from its official website. A dat file is a file that contains information about the names, sizes, checksums, and other details of the ROMs and BIOS files for a specific system.
Download a tool that can scan and compare your BIOS files with the dat file. One example is ClrMamePro, which is a free and powerful program for Windows. Extract the program files and run the executable file.
Click on Settings and then on Paths. Browse to the location where you saved your BIOS files and select it as the ROM-Path. Click on OK.
Click on Scanner and then on Load/Update. Browse to the location where you saved the dat file and select it. Click on OK.
Click on New Scan and wait for a few minutes. The program will scan your BIOS files and compare them with the dat file.
Check the results of the scan. If your BIOS files are green, it means that they are verified and match the ones from No-Intro's database. If they are red, it means that they are unverified or mismatched, and you should get new ones from your console.
By verifying the authenticity and integrity of your BIOS files, you can ensure that they are safe and compatible with your emulator and games.

Tips and tricks for a better gaming experience
How to improve the graphics quality and performance of the emulator
One of the advantages of playing Nintendo DS games on your PC is that you can improve the graphics quality and performance of the emulator beyond what the original console can offer. Most emulators have various settings and options that allow you to customize the graphics output and optimize the emulation speed. Here are some tips and tricks for improving the graphics quality and performance of your emulator:
Change the resolution and scaling: By default, most emulators will display the games at their native resolution, which is 256x192 pixels per screen. This might look pixelated or blurry on a larger monitor or window size. To fix this, you can change the resolution and scaling of the emulator to match your monitor or window size. For example, if you have a 1080p monitor, you can set the resolution to 1920x1080 pixels and - Continue writing the article. the scaling to 4x or 8x. This will make the games look sharper and smoother on your screen. However, this might also affect the performance of the emulator, depending on your computer's specifications. If you experience lag or slowdowns, you might need to lower the resolution or scaling, or adjust other settings.
Enable filters and shaders: Filters and shaders are graphical effects that can enhance the appearance of the games by adding colors, textures, shadows, lighting, etc. Most emulators have built-in filters and shaders that you can enable or disable from the settings or options menu. You can also download and install custom filters and shaders from online sources, such as this page. Some examples of filters and shaders are HQ2x, xBRZ, Super Eagle, CRT, Scanlines, etc. Experiment with different filters and shaders to find the ones that suit your preferences and taste. However, keep in mind that some filters and shaders might be more demanding than others, and they might affect the performance of the emulator as well.
Adjust the frame rate and frame skip: The frame rate is the number of frames per second (FPS) that the emulator can display on your screen. The higher the frame rate, the smoother and more fluid the games will look. The frame skip is the number of frames that the emulator can skip or drop to maintain a steady frame rate. The lower the frame skip, the more consistent and accurate the games will look. Ideally, you want to have a high frame rate and a low frame skip for the best gaming experience. However, this might not be possible for some games or emulators, especially if your computer is not powerful enough to handle them. In that case, you might need to lower the frame rate or increase the frame skip to avoid lag or stuttering. You can adjust the frame rate and frame skip from the settings or options menu of your emulator.
By improving the graphics quality and performance of your emulator, you can enjoy playing Nintendo DS games on your PC with a better visual experience.
