|Summary||07540: ckongpt2: Incorrect envelopes for sounds in all crazy kong variants on crazy climber hardware.|
The musical notes decay too quickly in mame, and have for ages.
real board video here.
in mame the level end tune sounds very different. there is much more sustain between the notes in it on the real hardware, creating a nice reverb imitation that can clearly be heard. Mame clearly goes duh-duh-duh, duh-duh-duh-duh,duh-duh-duh-duh, duh-duh duh duh... while the arcade goes more like duhuhuh, duh-duhuhuh, duh-duhuhuh, duh-duh duh duh.
The odd thing is that the very early emulation sounded correct to me, but ever since the psg emulation was "fixed", it's sounded wrong in these games.
I'm not sure what the issue is, but you can clearly hear the sound difference in how it sounds versus MAME. And the video agrees with how i remember donkey king sounding when i saw it back in the day as well.

There could be (and likely is) missing AY 8910 discrete filtering involved.

|could be, but as i said, the early emulations of the game didn't have the filtering either, and the audio sounded right to me. that's what's puzzling me. i don't see how filtering would extend sustain. strange.|
