Nice work !

@Folly said in Creating ES gamelists with media for MAME/lr-mess:

Screenscraper doesn't add a picture to it.

It works with screenscraper. You have to add a system and customize the rom path in SKRAPER

@mitu

It's working perfectly after updating the RetroPie-Setup script and installing lr-mess from the binary again !

@csl

No problem but I think we see things from a much different angle.

I don't know the exact answer, you should ask a "global moderator".
But, I think, it basically comes down to how much time the developers can or want to spend and what they think what should be added or not.

And when something isn't there, some people become developers themselves.
Perhaps you can contribute to the open source community too.

I think you can just add gameandwatch in line 50 of /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-mess.sh
I haven't tested though !
Let me know if it works for you, perhaps we can learn from this.

@folly said in How to get lots more Memotech MTX512 games working:

For example you could make a github page and then make subdirectories for ever system and add "readme.md" files in them.

I'm about as likely to be able to do that as I am to translate them all into Albanian :D

Never mind, fixed it :)

I think I'd crossed the streams while flailing at the options. The key is to add -gameio joy to emulators.cfg, so that it reads like this:

lr-mess-apple2 = "/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/apple2/retroarch.cfg apple2e /home/pi/RetroPie/BIOS -gameio joy -flop1 %ROM%"

And then go into the MESS menu and set the analog controls up like this:

The key is those "P1 Joystick X Analog" and "P1 Joystick Y Analog" lines - you have to make sure those are set to "None", which isn't the default. Take those two steps and you should be sorted.

@jimmyfromthebay a bit late now, but you should know we do not support third party forks of the software, such as

Valerino's fantastic alternative RetroPie-Setup script

although they are active here to assist: https://retropie.org.uk/forum/topic/25576/new-scriptmodules-lr-vice-xvic-gsplus-proper-lr-mess-integration

that said, your issue appears generic. note that the location of active overrides is found in the verbose log as requested in https://retropie.org.uk/forum/topic/3/read-this-first

@Folly

Done!

@WilsonB

You can use this project to make use of many(/not all) @Orionsangel 's overlays with ease.

Follow the instructions of the first post.
Make sure you have installed mame/lr-mess and lr-mame.
Then goto CHEATS/ARTWORK/BEZELS > Submenu and select Setup Orionsangels Realistic Arcade Overlays > roms/realistic.
Then add your roms in roms/realistic (or use the restricted part)

@dteam

That is just what I was thinking tonight.

Cool, we were on the right track ;-)

Well, still we have to learn allot about MAME, we are not finished yet with learning !

@shift I don't have dedicated threads for each individual lr-mess system I run, but the short answer is "more-or-less all of them".

Just to rattle off some of the ones I've tried on my Pi, with decent-to-perfect performance:

Phillips CD-i Epoch Super Cassette Vision V.tech V.Smile Various plug-and-play systems (both "official" and bootlegs) Tiger Game.com Fujitsu FM Towns

Once you get down how the core works (which admittedly is a bit of a nightmare), it's insanely versatile since it runs all the same systems as modern standalone MAME (according to the current docs, that's roughly 32,000; that link at the top is a good few years out of date). Arguably the most powerful core in all of RetroPie.

@theburgerking said in Integrating lr-mess quasi-cores into RetroPie-Setup:

Is there an lr-mame core? Could I build one? I have used lr-mess both prebuilt and built from source and I see from its build script that it just pulls from https://github.com/libretro/mame.git.

Yes. Both lr-mess and lr-mame are built from the same codebase you mentioned (forked upstream MAME), but with different build options, which results in different supported systems (arcade vs. non-arcade).
I was referring to MAME (the upstream project), not the libretro cores.

Does this mean that mame itself is the part of the mame distribution that can run that system?

Upstream MAME distributes only 1 binary which supports all systems included - either arcade, computer, mechanical, etc. There's no separate MESS anymore and I think hasn't been for quite some time.

Yep, same error. If I'm understanding that thread correctly, the only way around it is to have an older version of MAME? Which you cannot obtain unless you had a backup of it?

@metro-city

Ok, you are in the lr-mess menu, changing the controller settings.
You should do it in input(this machine).
(The controller settings done here are on top of the RetroArch controller settings)
When you exit the game these settings are automatically saved, depending on what loader command you used.
The basename and cmd lines will store the config here :
/home/pi/RetroPie/roms/fmtmarty/mame/fmtmarty.cfg
The other lines, using the media addon and the run_mess.sh script, will store it here :
/opt/retropie/configs/fmtmarty/fmtmarty.cfg
Once stored all other games will use the saved config.

Using the game-specific loader will not use above config.
If you changed something, using such a loader, it will store the config in a subdirectory with the gamename, and is only loaded when you load that game next time.
It will store it here :
/opt/retropie/configs/fmtmarty/lr-mess/gamename/fmtmarty.cfg

If you want to go back to the default settings you can just delete such a config file.

THANK YOU @dankcushions !

Your pointer was half of the solution so let me write the other half in case anyone else searches for this answer.

Setting the resolution in the retroarch Options menu did not have any effect until I also turned on "Alternate render method" in the same menu. At that point all resolution changes took immediate effect (upon leaving the retroarch UI) and now this all works perfectly.

I will write up the rest of my method to launch rom-less system soon!

Thanks again.

I am going to answer this one myself in case anyone else needs this info in the future. After looking through the run_mess.sh script itself, I was able to see that the message "hn613128pc64.bin NOT FOUND (tried in pv2000)" was trying to tell me that lr-mess was looking for the BIOS file in a pv2000 subdirectory of the main BIOS directory. Once it was placed there the logic to skip the software list/hash started working properly and I was able to launch roms that did not match the official hashes.
