Tutorial: Fujitsu FM Towns Marty with Lr-Mess

I have galaxy force ii (japan).chd in the roms/fmtmarty folder.

You are using a plain lr-mess runcommand and therefor the rom you added is not loaded.
Instead it will use the rom filename as "basename" for checking the hash tables (the softlist files).
This procedure is called solftlist loading or basename loading.
lr-mess probably expects the .chd rom file to be placed in the folder :
roms/fmtmarty/gforce2
The .chd file placed in above folder has to match the filename of the file in the hash table.
The blank .zip file can then be selected in emulationstation and the softlist loading procedure will then ultimately find the file if your configuration files are compatible for softlist loading.

mess_libretro.so

I see that you are using the old named mess_libretro.so.
This core name isn't used anymore for quite a while.
If you updated lr-mess lately retroarch can't load the core as it's now called mamemess_libretro.so.
It seems to be the case as your log file isn't that long and I don't see any loading procedures in there.

Of-course you can try above methode and it's really a good way of understanding how both mame and retroarch works.
However running a .chd with a runcommand not using softlist loading loading is in this case much easier so you don't have the need for suggested folders and blank files.
It then will require a media component (-cdrm) for example.
Although adding a media component sounds simpler it's not really the case.
Configurations have to match this type of loading too.
Therefor I made this project which will do all of this for you :

@Folly Thank you. I will follow the instructions to update and respond back with questions/results. I appreciate it!

@Folly I have it working fine now. Whew! :D

Only trouble is that it is slow. Do you have any suggestions to speed it up? Thanks Folly!

Folly

@duglor

Great job !
What method did you use to get it working ?
I would like to know and it might be interesting for others too.

Do you use a pi4 ?
Check with F11 how fast it's going in percentage.
With F9 you can alter frameskipping to speed it up a bit.

@Folly It was very complicated and had lots of random placements and trials. I will soon explain where i have the files and what files, etc. I probably have 3 versions of bios(es) in there and probably half are not needed, but i don't know which ones. lol. The entire set up was very strange with dummy zips and chd files in subfolders and odd bios(es) and an xml file in a strange location. Stay tuned in some days for a very odd writeup on where i placed everything and what i did to make this work.

@duglor I look forward to that write up Duglor.

@DTEAM Is this still the best way to install the fm towns variations at this time? May of 2023? if not, can you point me to a more recent rules version on how to do this?

What is this way, where are you referring to ?
Which variations ?
The best way, what do you want to accomplish what you can't do right now ?
What do you mean by rules ?

The original instuctions in the very post post.

Which variations ?

fm towns - various RAM - autoframeskip
etc

The best way, what do you want to accomplish what you can't do right now ?

a new simpler one shot installation like one of the main packages

What do you mean by rules on how to do this?

instructions on how to do this

@duglor

Best way is to use my project and learn how to use it properly.

I made an exception for you.
I generated a module-script with my add-systems-mamedev.sh front-end module-script and reduced the generated script.
So it will install only direct lr-mess runcommands for fmtowns with cdrom and 6Mb memory.
You can find it here (it will automatically be "burned/removed" after a week) :

Place it in ~/RetroPie-Setup/scriptmodules/libretrocores and install it from the experimental packages.

@Folly Heh. Yes. I'm guilty of being old. I was way better with all this just 7 years ago. Anyway thank you so much once more for your help!!! I'll be using this right away!
