No.02375 Tafoid Administrator Sep 6, 2008, 17:56	Regression testing finds no real regression. 0.65 is the first MAME with this game released and has the same behavior.

No.16023 MetalGod Senior Tester Jan 11, 2019, 12:44	Not happening anymore since mame 0.201 Fixed - 0.201: Q-Sound: Added device_clock_changed [smf]. Saturate ROM offsets (sound\qsoundhle.cpp). Apply ADPCM sample bank (sound\qsound.cpp) [superctr]. Added improved qsound_hle core. Use ROM lookups instead of copying tables at init and use enums for most DSP ROM addresses. Replacing memset at the cost of legibility (sound\qsoundhle.cpp). Fixes awful buzz sound noise in the Super Street Fighter series [Lord Nightmare]. Removed EEPROM MCFG macros [Ryan Holtz].
