Mame emulation speed faster on Retropie than on my PC
-
I just tested the 'Maximum Run Speed to 1.0x', it fixes the correct refresh rate but unfortunately makes the audio crackle.

Does this happen on every rom?

@windale
I tried setting Maximum Run Speed and still getting bad refresh rates :/ bummer . Try the game "Super Pang" and see for your self. -

Yes that's right. I'm using the latest spang rom from romset 0.181. Hmm what core are you using for mame? I'm using the default core that came witj mame folder lr-mame2003. Maybe It will work with different core/version?

@Floyd I'm not sure I understood you. You said that Super Pang in lr-mame2003 is playing at the wrong speed. In MAME 0.78 (lr-mame2003) it's supposed to be playing at 60 fps (Hz), which is correct. The MAME team didn't fix this until MAME version 0.133 (which is 57.42Hz). So in lr-mame2003 it's correct,
-
@windale Oh well that makes sense.. The lr-mame2003 uses an old 0.78 core no matter if I use 0.181 roms.
Anyways, I'trying to apply frame throttle and was looking through /opt/retroarch/config/all/retroarch.cfg but wasn't able to find a parameter which is responsible for frame throttle.. Can you point me where that max.run speed parameter resides? -

hey, sorry for taking ages but Hz is something that can be fixed pretty easily in the mame2003 code i think. is it just super pang that has should be 57.42hz? currently the following mitchell games are set to 60hz in the same driver (i think i can easily create a new driver for super pang if it's the only that should be changed):
"Dokaben (Japan)"
"Pang (World)"
"Pang (bootleg)"
"Buster Bros. (US)"
"Pomping World (Japan)"
"Capcom World (Japan)"
"Adventure Quiz 2 Hatena Hatena no Dai-Bouken (Japan)"
"Super Pang (World)"
"Super Buster Bros. (US)"
"Quiz Tonosama no Yabou (Japan)"
"Quiz Sangokushi (Japan)"
"Block Block (World 911106 Joystick)"
"Block Block (World 910910)"
"Block Block (Japan 910910)"
"Block Block (bootleg)"maybe there's a good resource for current mame game frequencies that I could refer to?

@dankcushions There are several games that play at the wrong Hz, some of them I reported on the lr-mame2003 GitHub. These all play at 60 Hz (which is wrong) :-
Robocop (57.4 Hz)
Bad Dudes vs Dragon Ninja (57.4 Hz)
Midnight Resistance (57.4 Hz)
Burger Time (57.4 Hz)
Caveman Ninja (58 Hz)There are probably a lot more. I got my references from the latest PC version of MAME 0.182 Arcade Only (which has a folder list of all game refresh rates in the left side bar) http://www.progettosnaps.net/arcade/ (you need to put the Arcade.exe in the offical MAME download folder http://www.mame.net/ before running !) and MAME32 0.78 which can be downloaded here http://www.progettosnaps.net/mameui/packs/MAME32_0.078_25-12-2003.7z

I've been Reading about this, and well, I don't have problems with my favourite games speed but yes I do have one single thing that bugs me and it's about Double Dragon 1. The game speed seems ok but the sound pitch is a Little higher than the original and sometimes sfx's sound really way too different from they actually are. Would this Hz thing fix that too?
