emulator cant find bios

[asdfasdffd]

I changed the program the bios and bin files open with and now emulator wont work. How do I change the file back to the default program? I tried deselecting the "open all files of this type with this program" option off and redownloading it but it wont work.

I would like to know a few things before I can help.
1.) Emulator *Kinda important for this question*
2.) What are the files?
3.) Settings for the emulator.

But for general troubleshooting, go back and download the files again without altering them. Unless it's like zipped, then unzip it. Try it on the emulator again, if it doesn't work, come back with the answers for the above questions.

What you've done here is change the file association for .bin files, but only in windows explorer (the program that lists your files). This does not affect how other programs see or read your files. In this case, changing the file association for .bin files does not affect nullDC's ability to read the .bin files.

I tried deselecting the "open all files of this type with this program" option off and redownloading it but it wont work.

If .bin files were already associated with a different program, it won't have saved what the old program was, as the defaults are usually user-set. Unless you're loading your .bin files by double clicking them, this doesn't make a difference.

tldr; the "all files of this type" bit is irrelevant, just direct nullDC to the location of the file. If the file doesn't show up under the browser in nullDC's settings, it likely isn't a supported file type.

dc_boot.bin and dc_flash.bin just go in the data folder of NullDC, no settings need to be changed no file association to be done or undone, NullDC will automatically recognise the bios images if they are stored in the correct location, being the data folder that is a sub folder that the NullDC program is stored in.

dc_boot.bin and dc_flash.bin are the actual names of the files.

file association just makes it so certain file types if double clicked will auto open in the program they are associated with, but that does not stop those file from working in other programs from opening the files, also NullDC does not open the bios images that way anyway so should not be associated with NullDC.
