Summary	08938: dino, punisher, wof: CPS Dash is much less friendly to QSound LLE than CPS2.
Description	In the Dash games SFX are playing quite adequately, but music is suffering because of heavy downslowing and samples stuttering despite the full speed of overall emulation.
Steps To Reproduce
Additional Information	The base of build is got by git clone -b mame0270 --depth 1 https://github.com/mamedev/mame.git mame0270. The only change is the #define QSOUND_LLE line, added between #include "emu.h" and #include "cps1.h" lines at the beginning of cps1.cpp and cps2.cpp drivers.

No.22383 hap Developer 7 days ago	I tried "dino" and yes, music is slow and I hear some other glitches. MAME runs at 100% speed.
No.22386 VasiliyFamiliya Tester 7 days ago	The Punisher and Warriors of Fate also shows absolutely same results.
No.22392 StHiryu Tester 5 days ago	Really not related but, yesterday I played The King of Dragons and noticed some game slowdowns, the most important after defeating the final boss of the game, when a lot of items appears on the screen. This never happened to me in previous versions...
