new mame2010 folder structure

Very informative. Thanks.

markwkidd

I submitted a new PR to automatically generate and place a shortened mame.ini if there is not one in the ini folder: https://github.com/libretro/mame2010-libretro/pull/94

markwkidd

That PR is approved. From here on, if the user doesn't have a mame.ini, a minimal one will be generated in the ini folder. I hope that it has the necessary settings to keep things functional for everyone while not 'stepping on the toes' of the core options.

I also discovered a pretty fundamental bug that somehow doesn't seem to be causing problems in general. It does however throw up an annoying speedbump to implementing 'hiscore' support in mame2010: https://github.com/libretro/mame2010-libretro/issues/95

@markwkidd Hello there, MAME2010 now compiles in Ubuntu 16.04, but MAME does not start any game. Retroarch crashes and Ubuntu just reports back that This package does not seem to be installed correctly." It was a fresh install of the core in Retropie/Ubuntu. On the same machine, this core works in Retroarch for Linux, as precompiled under the Nightly Core Builds. Would an install log help or shall I provide anything else? Cheers!

If you can please post a pastebin link to the install log as well as the retroarch log when it crashes.

@markwkidd Unfortunately the logfile seems to be too large for pastebin. It is 3.6 MB.
You can download it from there:

This is interesting:

The error tells me that no files are there, but the files are there, they all run e.g. with MAME2003, whily MAME2010 does not find them (in the Arcade folder).

Will dig further

@estefan3112 mame2010 uses a different romset to mame2003. what works in mame2003 will almost certainly NOT work in mame2010. you need to get the right romset.

Seems like I have the same issue with a newly build lr-mame2010 on an Odroid XU4.
I definitely have a matching 0.139 10yard.zip rom but still the core complains that it allegedly cannot find any of the modules (which definitely are inside the ZIP).
With lr-mame2014 (and a matching rom obviously) it works without any issues.

Any idea what might be causing this?

Best,

I can confirm that the issue is definitely caused by the new build.
I have replaced the core with a known-to-be-working build from a couple of weeks ago and all roms work flawlessly.
Only the new build complains about the missing files (all of them) inside the zip.

Thanks. Could you post a log?

That seems like an ordinary missing file type of log. Until these updates mame2010 was looking for files in unpredictable places. Could you make absolutely sure that you have a file with this path and name? /home/pi/RetroPie/roms/arcade/10yard.zip

If you have that file in that location do, could you open up that zip file and confirm it contains these files?

@markwkidd I can 100% and absolutely confirm that not only this file 10yard.zip is exactly in that folder but also that it includes all of the mentioned modules.

Just to re-confirm - as soon as I replace the core with a core that was build several weeks ago it just works fine.

Well dang, it's always nice when the answer is that simple for everyone. This problem hasn't shown up yet so you'll pardon me if I keep making some shots in the dark while I try to narrow things down.

The next most common source of issues in general has been from mame.ini files so I want to check on that. (Next might be .cfg files.)

Do you currently have a mame.ini file in a folder called `libretro saves folder/mame2010/ini ?
If so, is it one you placed there, or was it autogenerated once you updated your core?
If you do have a mame.ini, could you make a backup copy, delete the mame.ini, and try to start 10yard.zip again?

TillmanZ

Actually I don't see the libretro saves folder. Where should it actually be?
I do have a mame.ini in /opt/retropie/libretrocores/lr-mame2010 but I have put it there (trying to fix the loading issue) using a mame.ini from an earlier build.
Because this current build script apparently does not generate a mame.ini file in this folder anymore.
The install_lr-mame2010() function in the lr-mame2010.sh script only copies the mame2010_libretro.so and a README.md file.

Tillman

@dankcushions I forgot to mention that my Romsets work perfectly in Retroarch with the new MAME 2010 Core, but that the same Roms do not work in the Retropie reincarnation! I also was suspicious of a different romset needed, but since it works perfectly in Upstream Retroarch, this cannot be the case.

markwkidd

Somehow there must indeed be a path issue. I'm working to add more logging to the game loading process to see if we can narrow this down.

I'm not so familiar with RetroPie's path structure, but I believe for RetroPie this is the same folder where the ROMs are stored. Theoretically that means you should find a subfolder called mame2010 within that folder where you will in turn find the ini folder.

dankcushions

@markwkidd bingo! by default, retropie save folder is the content (rom) folder for the core in question.

markwkidd

@estefan3112 and @TillmanZ I have updated mame2010 and I hope I have fixed the issue for you -- I think it was an inconsistency in how slashes were handled in the content path.

I have also added some more logging, which I hope will be helpful in case its still not working.
