Could you check if the Storage permission is granted? You can see this from the app's info screen by following these steps:

1. Open the device's Settings
2. Go to Apps
3. Find and select "melonDS"
4. Click on Permissions
5. Check if the Storage permission is enabled

If the permission is enabled, then it's possible that you have an invalid BIOS file. If the permission is disabled, try enabling it and try again. If it was disabled, let me know since that shouldn't happen.

Can you use the latest beta v1.3.0 and open a new issue? The latest version does not fix the problem but includes additional info that will help to find the cause.

If your problem is not yet fixed, try the latest Beta 1.4.0 release. If the problem is not fixed, please open a new issue.
