    I tried using MelonDS in the Experimental Nintendo DSi mode

Selected a DS ROM to play / test

And I constantly get prompted for Bios file

which I need to dump my personal DSi Bios in a folder and in settings select the correct Bios path which I did

These are for DSi [USA]

bios7.bin bios9.bin nand.bin. firmware.bin

  1. Once created a Bios folder 📁 and placing required bios / firmware / and files.

Placed Bios folder inside the NDS ROM Folder

  1. Go back to MelonDS and select the Bios directory path before launching a game.

  2. Select any DS ROM and launch Game does launch successfully it's just you constantly gonna get prompt that Bios are incorrect

Add screenshots if the issue can be visualized.

You also need to set the directory for the BIOS files for the DS to play DSi games. Try setting that folder and let me know how it goes.

Actually, all files (except bios7.bin) are completely empty (0 bytes) (you can already see it on the screenshot). You may have dump the BIOS incorrectly.
