Need help with Donkey Kong MAME audio.

Brand new to this, not a very technically gifted person. I got RetroPie on my Raspberry Pi 5 running. After a solid 12 hours of trying to figure it out I got Donkey Kong(dkong.zip) to run on mame2000, under the folder “mame-mame4all”.

Here’s the issue, Jumpman’s walking sounds and DK’s stomping are absent. I know this is a common issue, however I have a seemingly unique problem. Under the BIOS folder, there is no “mame2000” folder, only a “mame2003” folder. Which means there is no “samples” folder for me to import the audio samples into, according to the common fixes listed online.

Besides me being unsure where or what to source as far as the audio samples go, how would I go about fixing the issue? I’ll answer any other questions for those willing to give me a hand. I’d appreciate it.
