MAME development: lr-mame2003 Updates

UDb23

@Riverstorm I too was looking at recreating the blue hue for Depth Charge. As Libretro overlays are supported I will try with a full screen dark blu overlay with a low opacity settings and see how it works. Will let you know.
Also I'm making/adapting some bezels for the new correct core aspect ratio fixed by Dank in lr-mame2003. Idea is to have maximum gaming area with integer scale factor in 1080p and bezel covering remaining black areas.

@dankcushions Thanks for trying to fix Deep Scan sound.
This game is basically an enhanced version of Depth Charge (it adds color and the "radar" at the bottom). Therefore sounds are supposed to be the same as Depth Charge.
Invinco sounds are not related to Deep Scan.
Depth Charge does use an external sample file; maybe you can modify the code to look for these samples.

i'm having a play with the code and nothing seems to be working. i think this is just not supported in this version of mame i'm afraid :( advmame or mame2010 may work properly

@dankcushions thanks a lot anyway. Efforts really appreciated.
As far as I know even current mame version does not support sounds for Deep Scan.
Either nobody cares or it is difficult to implement (as you just confirmed).

Deep Scan looks great I guess that one slipped under my radar! It's nice to discover new gems. :)

That would be great filling in the black areas. I like the looks of the Depth Charge bezel on Mr. Do's Arcade but I think it would take up to much of the actual game areas as most of the bezel is top/bottom coverage (combined marquee with the control panel it looks like) but it's a nice bezel none the less.

I'll check if Depth Charge uses a specific external sample zip file (that could be reused for Deep Scan) and let you know.

The current samples use depthch.zip:

longex.wav
shortex.wav
sonar.wav
sonarena.wav
spray.wav

Riverstorm

In case you didn't know sound samples for Depth Charge (depthch.zip) do work in both advmame & lr-mame2003. I saw a few references to Deep Scan (invds.zip) using invinco sound samples but also found this. The information is a bit contradictory.

@Riverstorm thanks. Invds.zip does use invinco samples but only for the invinco game.
Talking about sub games I recently discovered: "the deep" and "In the hunt". Both are evolution of Depth Charge and really enjoyable in lr-mame 2003 :-)

Sorry, I am confused, what is the name of the Deep Scan game ROM?

Thanks for the tip, will give them a go here later today!

Ah, I see now button 3 toggles between the two games.

@dankcushions Much appreciated sir.

Binaries are updated.

Has anyone looked into adding "autocenter" to the analog control options for lr-mame2003? I end up using mame2010 for a lot of games that had analog controls because mame2003 lacks the "autocenter" feature.

@dankcushions The core input remapping addition was fantastic! Great work. mame2010 needs this too.

hmm, what does it do? or can you maybe give me an example game where it's a problem not having that feature? i've not had a problem with the analog games i've tried.

cheers! but that was another developer from libretro - hunterk :)

@dankcushions While playing a rom that has analog control the mame2003 Tab menu gets an additional option called "Analog Controls" it is the 4th option after: Input (General), Input (This Game), and Dip Switches. The Analog control option lets you adjust the settings in order to get a digital D-Pad to mimic Analog Controls.

For each axis there are settings for:
Joy Speed
Reverse
Sensitivity

In mame2010 there is an additional setting per axis:
Autocenter Speed

Basically in mame2003 if you push up on you D-Pad it mimics pressing up on the analog stick but when you let go of the D-Pad the emulated analog stick stays in the up position. You have to press down to bring it back to center and if you press down for too long you go past center into a down position and if you don't press down long enough the analog stick will register as slightly up.

In mame2010 because the analog controls autocenter when you press up on the D-Pad the analog control go up and when you let go of the D-Pad the autocenter feature brings the emulated analog stick back to the center position. How quickly it centers depends on the autocenter speed setting. This helps make analog games control much better with a digital D-Pad or arcade stick.

For example in "Escape from the Planet of the Robot Monsters" if you use mame2003 you press a direction and you will you continue to run in that direction even if you have let go of the D-Pad. In mame2010 you only run if you hold down a direction on the D-Pad. Letting go of the D-Pad autocenters and the character stops moving.

Pretty sure the same goes for Food Fight.

For reticle type shooting games you can turn the autocenter speed to 0 so that the reticle isn't always trying to recenter itself.

That turned out longer than I expected!

@dquez thanks for the explanation! that sounds useful but it doesn't sound like something i'd want to do, as it's core mame input functionality and probably quite hard to port between the two versions.

couple of big ones:

August 2nd 2017
Mortal Kombat 2/3 (and others?) sound distortion fixed! these games are now fully playable on pi3. this fix was also funded by @GreenHawk84 and @vince-geekcore - thanks both!
August 5th 2017
Killer Instinct 1/2 now work on x86 and pi! thanks to @markwkidd - kinst loads, and runs at about 2 FPS on pi3. very unplayable, so be careful what you wish for ;) however x86 users can at least run it, and it should be playable.
