lr-mame2003 driver improvement and backport
-
@Riverstorm thanks for all the infos :) I'll make sure to check it out, and update my games lists accordingly.

Oh, sorry this thread is mainly about mame2003_plus_libretro and not lr-mame2003.
Apologies are on me, I was not aware that mame2003_plus_libretro existed. But what exactly are the differences to lr-mame2003 if both are maintained? Just two parties updating mame2003 alongside each other?

Shameless plug, again :)
Are you following me?
I will try your tool and CSV filters very soon, and I will also try not to OT any more threads ;) -

I seem to be interested in the same subjects as you are :)

the two exist separately (at the moment) because we don't want to break existing mame2003 functionality/romsets. the plus changes started life as changes to mame2003 but there were a few issues with builds failing and samples not working, so having it as a separate entity frees the developers from these concerns and also means that mame2003 remains stable.
really, mame2003plus should a branch of mame2003, or something like that, but it's semantics i suppose.

To add to what Dank mentioned a programmer named Arcadez decided to add and fix additional games not working in lr-mame2003 but it was causing some minor issues. So then it kind of became a derivative of lr-mame2003 and has kind of taken a life of it's own. Their are 3 very active developers (Arcadez, @markwkidd & @grant2258) that have added 100+ games and updated another 30+.
I think the goals are similar of both projects in getting some lost classic arcades games working but it allows each the freedom to develop down a path of their choosing without worry of breaking lr-mame2003 or vice versa but they can also share the code too if there's a fix one or the other may utilize.
Basically they both run the same games but mame2003_plus_libretro has some additional games that lr-mame2003 does not. lr-mame2003 has 2 games that mame2003_plus_libretro does not listed below.
Only exist in lr-mame2003:
• Cabal (US set 2) (cabal2)
• Urashima Mahjong (urashima)I haven't updated it in about a week so the numbers are actually higher but mame2003_plus_libretro has 4,810 total ROMs, 4,687 are the 'hash' duplicates of lr-mame2003, 92 ROMs are new only to mame2003_plus_libretro and 31 ROMs have been updated. They may be either clones or sound samples, etc.
ROM Count:
Total ROMs in mame2003_plus_libretro - 4810
Duplicate ROMs matching lr-mame2003 - 4687
New ROMs only exist in mame2003_plus_libretro - 92
Updated ROMs in mame2003_plus_libretro - 31 -
old games that ran 47 fps and below are now working in mame2003 and mame 2003 plus (bally atari and more)

Why then is lr-mame2003 the recommended emulator? It seems everyone should use mame2003_plus?
-
The vanilla 0.78 ROM set and samples used by lr-mame2003 are more accessible, making it an easier setup for most.
-
@mediamogul but in the docs for mame2003 plus it says "The MAME 2003-plus core accepts MAME 0.78 ROMsets for 99.9% of games" ?
-
If you were to make use of the vanilla 0.78 ROM set with lr-mame2003-plus, 99.9% of the games would work, but there's really no reason not to use the original lr-mame2003 and get that extra 00.1% that would otherwise be incompatible.
-
@AndersHP - Also remember right now it's still experimental. It's in that section. It's in a very rapid development cycle and some things might be broken and fixed an hour later. I've downloaded from source 5 or 6 times this past week.
You can definitely make it your preferred emulator (especially if there's new games that are favs) if you have the correct ROMs to build a set and are alright with some occasional quirky behavior.
You can also pull only the new/updated ROMs that run only in Plus and use the Arcade folder that allows multiple emulators for one platform. I can make a DAT for that too.
Any testing and feedback is great of what works and what's broke. It might become the preferred emulator down the road or merged with lr-mame2003 down the road. It's hard to say as folks higher up will need to decide a course of action.
-
plus has had issues with failing builds and so forth. it will get there! just be patient whilst development goes on :)
-
When I install this I get:
Could not successfully install . /home/pi?RetroPie-Setup/tmp/build/lr-mame2003-plus/changed.txt not found.Then it tells me to see the log to see what the error was about. TO whom can I provide the log file?
-
@edwardthehuman What version of RetroPie are you using ? I remember this has been corrected a few versions ago - you should update your setup script to 4.4.
-
@mitu Hi, i tried it first using 4.3 and didn't work. So I just updated it to 4.4 and still the same result. Thanks
-
@edwardthehuman It seems the github repository is undergoing a few changes which have not been picked up by the install script. Wait a few days until things settle down and I'm sure it will work again.
-
@mitu Okay I will wait a few days before installing it again. Thank you

I think this PR should update RetroPie-Setup the way it needs to in order to compile again: https://github.com/RetroPie/RetroPie-Setup/pull/2369
I've been making changes oriented towards having a long-term stable period in the repository. I've updated the license and documentation within the repository to match github convention.
I've also been removing one of the layers of abstraction between libretro and MAME around file handling functions. There's a bit more to do but the end is in sight. Not the sexiest section of the code, but this project is intended to make it easier for new developers to come along in the future and understand how mame2003/mame2003-plus locates, loads, and handles files internally.

I seen youve been doing quite a bit of work mark. I noticed issues when changing the sample rate the changes your doing are needed and appreciated. It could be a wild guess where a variable was being set at times in the options
-
@grant2258 I actually started out just wanting to clarify how the paths were selected for the various filetypes, specifically with samples in mind. Of course it got to be a bigger project than that as these things do.
I would still like to simplify the file path section but I think with my latest PR I am done for now. Assuming there are no regressions.
The only other project I have is to try figure out why I don't have access to the libretro logging interface at some times when I think I should, for example when samples are being loaded. I've been told in the past to try to avoid logging to
printfbut I must not understand something about the libretro log callback because it's not always there when I need it.
Contributions to the project are always appreciated, so if you would like to support us with a donation you can do so here.
