Summary 06674: ddragon2: ddragon2 voice not sounds the same and slowdown is low if comparing with arcade
Description Since when ddragon2 was added the gameplay had extreme slowdown.
I had played very much ddragon and ddragon2 and had slowdown, but not at extreme.
Brazil had a mix of bootleg and original PCBs.
Please see the link below. Is a video capture of ddragon2 arcade. Seeing look being world version.


The game has slowdow, but much few if comparing with MAME.
I understand that recently was changed the CPU frequency in emulation, but even thus in some areas has slowdowns.
Another detail is that if the PCB used in the video run smooth with the same cpu frequency that was used in MAME previous versions have a problem in emulation with ddragon and ddragon2. ddragon and ddragon2 use the same MAME driver. ddragon has the same issue and current version even with changed cpu frequency has some areas the slowndown is extreme that has problems in control input. I had played a original ddragon PCB and not had extreme slowdown mainly in control inputs. The video in the link not has much slowdown when more of 3 sprites is on screen. MAME has high slowdown if more of 3 sprites is on screen at same time.

Another main detail is that the some sound effects and few voices not sounds the same in MAME.
The main example is the voice when the player character throw a object. Advance the video in 6:25. For test in MAME the begin of first stage has a object to throw.
I have posted a question for the youtuber if the PCB has any hack. Now waiting a reply.
Another game that the character voice sounds strange for me is Rygar, but will be another post when I see a real video capture.
Thanks Tafoid, Fujix, devs and others. Good luck in your path.
