I compared the SCC sound with the original cartridge and WonderTANG! 2.0b and found that there is a channel somewhere that is not sounding. It is easily found at the beginning of stage 2 of Salamander and I am attaching a video to confirm.
SCC emulation may be incomplete.

Since tnCart with 1.02d hardware sounds fine, it is possible that there is an issue with the software. https://x.com/Yukky37x/status/1832428187659227521
I posted this on the msx.org forum and others have had similar experiences, so I have registered this issue here. https://www.msx.org/forum/msx-talk/hardware/wondertang-who-wants-to-juice-up-your-msx?page=45
