The ADCPM OKIs in MAME play way quieter than they should. From what I've compared with, games/systems that use them seem to consistently sound more accurate with the volume set to around 300%.
For example:
- PC Engine CD OKI MSM5205 (voices in visual novels, etc, get drowned by the CD audio)
- Street Fighter OKI MSM5205 (can barely hear the "Round one" voice)
- Super Pang OKI MSM5205 (sound effects too low)
- Diet Go Go OKI MSM6295 (voices and other sampled sounds don't stand out from the music as much as they do on real hardware)
- Sailor Moon OKI MSM6295 (percussion in music almost can't be heard)
Steps To Reproduce
For a quick check, in Diet Go Go just start a game in the default stage and hit some enemies. The sound effects (and drums in the music) don't stand out as much as on real hardware recordings.

Could you see if you can adjust the levels in the slider menu (TAB -> Slider Controls) to find some accurate to recording?
I'm acknowledging this as you have a pcb recording which can be used as reference.

Sounds more accurate to me when the volume of "OKI MSM6295 ADPCM ':oki' Ch.0" is set to 300%.
Would finding pics of the board help getting the actual proper values for these?
