Extremely inaccurate triangle pitch in VS. Excitebike FDS (not arcade version)

[riggles1]

Submitted this issue to the upstream fceux as the same thing happens there

Start VS. Excitebike.fds and on disk B start the original excite mode, in both the menu and gameplay on the emulation of the triangle is at a wrong pitch.

I hope this issue gets some priority as it's a pretty big one and I love this emulator (main use with Pi4+CRT), other than to bring attention to it here as well, anyone know what what other fds games have the sound emulation affected like this?
