Breath of Fire IV audio problem

if you are not using emulated cpu overclock, if not alternative setting in emulator audio settings then test rom quality:

[hasher]

-- easy: check the hash using duckstation - BIN+CUE, MultiBIN+CUE or CHD

* open DuckStation; [standalone version]
* select the game; [just highlight it]
* right-click to open the pop-up / local menu;
* choose "Properties...";
* choose "Compute Hashes..."; [on the lower right side of the window]
* wait;

if the result is GREEN, your game backup is perfect. Good ROM/DUMP!

if the result is RED, bad backup, bad dump, BAD ROM.

-- or do it manually

bonus tip on linux: for multiple files with more than one file extension

bonus tip by u/ anievo: type powershell at Windows Explorer address bar, then:
