i just made a PR with an example for stonebal. is this like you indended this to be submitted? or is there a better way. i never did this before so it might look strange to you :-)

What you submitted looks viable to me, it should be straightforward to convert to a code patch.

Thank you for also testing out the docs, and providing feedback. I will add some language about how to find MAME's button names.

I'm glad I asked for your help before your trip -- that sounds awesome! I'll try to code your stonebalbutton names ASAP in hopes you can see that in effect before you go :)

also how do we know the button order, e.g. why is it 1,2,3 for punch and 4,5,6 for kicks in sf? could also be vice versa, is there a general rule for that?

hey cool thanks. i will test this today. i'll be leaving around second week in june so there still is some time...

i have one additional thought about this. please tell me your opinion. i have the feeling that the way of implementing all button schemes is s lot of work and can almost never be finished plus you always have to deal with it again for new games added to mame2003-plus. i thought more of a more generic approach like coding the module for button naming only once (for up to 8 buttons) and for each game apply this generic module filled with the button naming metadata of a general or per game cfg (i would prefer a general cfg)

sf_button1="Jab Punch"
sf_button2="Strong Punch"
sf_button3="Fierce Punch"
sf_button4="Short Kick"
sf_button5="Forward Kick"
sf_button6="Roundhouse Kick"

stonebal_button1="Shoot/Fight"
stonebal_button2="Push"
stonebal_button3="Pass/Tackle"

stonebal2_button=stonebal_button

this way you can finish this whole coding approach applied for all games and if there is an entry in the cfg it will show the respective values in the menu. This database can than be filled from various people and reviewed/released by you.

does this make sense?

robertvb83

it seems like such button naming DB is already existent! there is a controls.ini / controls.dat / controls.xml file. I cannot find one that is later than 0.141.1

there is someone who made a github project to convert controls.xml into controls.json here. which is discussed here

it looks like something that could be used here?

I think you are really onto something here! It might be possible to write a script that parses the controls.dat/ini/xml and turns it into something that can be automatically added to mame2003-plus. BTW MAME 0.140 is probably a good starting point anyway.

I have some ideas based on your post on how this could be implemented at a large scale and it's killing me not to be trying the ideas out right now! hehe

robertvb83

@markwkidd ok i guess then the old approach is not so relevant anymore, however i testet street fighter and it works perfectly

also ingame the functions are represented correctly!

Yay, thanks! That is definitely relevant. Starting with a solid baseline is something I have started to appreciate as a philosophy when it comes to input code.

you should be able to grab all this info from the latest mame with xml or any other list function it provides and parse it with python. just be careful with the usual rom zip name changes ect because different revisions of roms sometimes user different inputport settings

Looks like the system32 games have a lower pitched audio. Not sure when it started. The bug is only in Plus. Original 2003 is fine.

yea does seem off but so does the driver I compared the cpu speeds and ym speeds in lastest mame and they dont match up with the speeds our driver has. mame2003+ aims to run the at the speed the hardware intended. I could be a glitch in timing system as well cant rule that out.

You can see mame2003+ when playing data east games. mame2003 just plays these games too fast the pitch is completely in them. I dont know how fba handles robocop if its running 60fps the pitch will be wrong like mame2003.

markwkidd

Is this one of those issues which can be resolved by turning off/down the RetroArch 'audio stretch' function?

I tested in mame078 mame2003 mame 2003 plus none of them are correct to current mame in pitch its more pronounced in mame2003+ because the timing of the driver wrong

its just not right none even in mame 078 mark

the ym soundchips are different speeds and the other soundchip i cant remeber the name of is off speedwise as well in the driver. It would need updated to work properly on all versions of mame2003 if fba is the same as mame2003 something is wrong there too

grant2258

@markwkidd here is the difference between mame2003 and mame2003+ its easier to tell on this game start ddragon2 its 57.44 fps youll clearly hear mame2003 is playing the audio to fast and the game as well

dankcushions

@grant2258 turn down/off audio skew and mame2003 plays them at the right speed. there's no bug.

markwkidd

I am curious about how it sounds with Audio Skew turned off.

Regardless of the results of that specific test, I am reminded of a thought I had in the past.

Are there downsides to recommending that people in general disable Audio Skew for the mame2003-plus core or turn it down to some amount below its audible threshold?

The minimum audible Audio Skew number was determined somewhat informed manner in a libretro forum thread that I can find now that I have the right term.

yes - the point of the default skew setting is to skew (speed up/slow down the audio/video) games that are close to 60FPS to 60FPS (or, whatever your screen hz is). otherwise, you get judder with vsync. the use case for this was NTSC games with strange 60.X timings, i believe.

now, i personally think the default setting is a little too large (you can easily notice the effects skewing a 57.4fps game), but that's a retroarch problem. i think they would be open to lowering the default. i think that's a much better solution than getting the users to mess with the settings, or fooling the API until it thinks you're running a 60fps game.

grant2258

yea need to get that magic number to test it out. The think that confusing though is games like mk and stonebal (i just found out about this one) are working ok on mame2003 without the audio scew it just seems the 57 fps are getting chomped by this. On our end 2003 what we are doing is only playing 57.4 worth of sample time its the audio timing of 48k taking the 60fps time that pushing the framerate up with the audio scew as is. I originally thought the timing changes the samplerate it doesnt. The only way you can change the sample rate is with ra settings as far as i can tell

markwkidd

OK I will locate the libretro forum thread about the audio skew and see if RetroArch is amenable to a PR lowering the default. If not maybe it's worth a note somewhere in the mame2003-plus docs.

On this theme, in a general way:
@dankcushions I would also really like to help create a PR to add the "RetroPie udev ordering patch" to RetroArch as an option in the cfg. I know there is an issue about it that you participated in but I think that's could be another example where a PR is the best way to communicate with RetroArch.

Unfortunately I haven't yet added a RetroArch cfg option so I'll need to learn.

grant2258

@markwkidd we dont need an audio screw for mame2003+ only 2003 needs its atm setting it shouldnt effect us at all we are within the ra timing system not fooling anything just playing the sames sample frames per second to what it shoud be can add both options as a core setting if you like though. Midway will have to be the new way 30fps is too much for audio scew as far as im aware
