@dankcushions So glad to help contribute to the improvement of Mame on Retropie!
Thank you good sir and @markwkidd for the new additions and @dankcushions for keeping this thread of enhancements and improvements you've done.
-
Oh, wow, well done and thanks for the update!
I take it an update from source would sort it out then?

yes! you could try via binaries first, as they may have been updated. source will take about 30 mins on a pi3
-
@dankcushions Awesome updates, will update when I get of work :)
-
@dankcushions When this update says 'sound distortion' fixed for Mortal Kombat 2 and 3. Does it mean how the games are really quiet? I've updated but no difference this end.

no - the horrid distortion and delay that previously happened after ~10 mins of play. volume can be easily adjusted via the service menu: https://github.com/RetroPie/RetroPie-Setup/wiki/lr-mame2003#service-menu
-
@mrjordaaany that will never change, the games were designed with a starting volume. You have to adjust that on the actual game options.
-
@dankcushions @GreenHawk84 ah I see. Thanks for the info.

@dankcushions said in MAME development: lr-mame2003 Updates:
this fix was also funded by @GreenHawk84 and @vince-geekcore
Is it possible to request specific fixes to the libretro team by funding ? How?
As you may remember I'd like to have sounds in Deep Scan (Invinco/Deep Scan dual game).
For a Mame developer it shouldn't be complicated.Thank you all for making lr-mame2003 better and better!
-
@udb23 have you tested it in MAME 2010 or AdvMame?
-
@udb23 we use www.bountysource.com to post bounties on github issues. this one was fixed by a developer new to libretro, i believe. the power of open source!
however, i think your issue would only be viable if it's working in MAME 0.78 standalone (like the mk2/3 issue was). i think if it isn't, then you're better finding out which version of MAME it does work, first.
-
@pjft According to mameinfo.dat sounds are still not implemented in mame driver. It should/could use samples from "Depth Charge".
-
@udb23 I suppose I was kind of getting at what @dankcushions suggests. If you find a version of MAME where it works, maybe someone will try to backport it. But if it's not available anywhere, that'd be harder.
-
@dankcushions Understood thanks. Did more checking and unfortunately it seems Deep Scan still has no sound even in latest mame. The fact is that vicdual machines had same mainboard but different specific soundboards.
On the other hand recently support for sound daughterboard in N-sub (another vicdual rom) has been added. I posted a comment on that github commit (here) requesting if this could help also for getting sounds in Deep Scan. If anybody wants to request it too there, maybe it can help ;-) -
@udb23 I am thinking maybe the best value in this kind of request would be to try to fix the root cause of the Service Mode issue—games like Sarge, Xenophobe, Rampage and a bunch of others that just stall at launch. I suspect there is some common cause (underlying original hardware similarities?). May it is already being tracked—but this would give us a bunch of games that we wouldn’t have to setup with other emulators.

WOAW so cool to found some one working on MAME 2003 for PI (and PC)
It is one of the best emulator ever :)
On xBox 1, with a 700Ghz proc and 64 Mo RAM we can play so many games, why not on PI lolOn xBox Mr gamezfan help by IQ_132 update our MAME 2003 with many code and drivers take on the last PC MAME versions ... to have more games fixed and 100% playable and some new one, always on the old MAME core faster on old machines :)
Maybe, i think it is a good idea, you can speak with him and watch his code, compare with yours, to upgrade PI version like the xBox version. The best one i think for light computers.
If i remember fine, it is based on MameDox that is a fork of MAME 0.84.http://www.emuxtras.net/forum/viewtopic.php?f=183&t=5732
The project began in 2013 ...

@darknior mame 0.78 has an x86 dynarec for the MIPS cpu used by killer instinct, so it already runs much quicker on x86 hardware (eg a PC, or the original xbox). pi systems have an ARM cpu, and there is no dynarec for that. their code is not helpful here - i've already looked at it.
-
@dankcushions Ok i understand it will not help for the CPU because it is not an ARM one for sure.
But it can help you to take fix for games, and drivers updates adapted for an old MAME. IQ_132 work hard a lot for it ...
I think it is a good idea ... or maybe not :pLife is game, just play it !
-
So news updates to come :)

@darknior could you mention any specific games that this fork of MAME is better at than mame2003? That would be a more helpful starting point :D
