HSD_Synth_80389334()

int HSD_Synth_80389334 ( int sfx_id, u8 vol, u8 vol2, u8 pan, int priority, u8 itd_flag, float pitch1, float pitch2, float mix_main, float mix_auxA, float mix_auxB )

static

Todo

Currently 95.4% match - register allocation shifted by 1 (r29 reuse for loop counter and computation missing)

Todo

Type pun writes ratioHi+ratioLo as u32; no union in AXPBSRC. Needed for match - AXPBSRC lacks a u32 ratio field.
