Tutorial: Fujitsu FM Towns Marty with Lr-Mess

bbilford83

@Folly This worked!!! Thank you very much. I am messing around with the settings though as it runs slow with my standard underclock for the system. I am thinking probably I will need to set the cpu underclock game-by-game if that's an option - maybe by setting it in mame rather than retroarch?

This makes me wonder if some of the other games I tested that didn't work would work with the 4mb core.

What kind of pi4 do you have ?
If you have a one with 8gb or a newer 2/4gb you can make the pi4 run faster with a higher cpu clock without overclocking 1800Mhz just like the pi400 does.
That way the performance of your pi will also increase a bit.
It's a setting in the /boot/config.txt but it has been added in the newer Debian 11 Raspberry pi OS but, as far as I know, it will also work if you add it in the /boot/config.txt of the older Debian 10 Raspberry pi OS .

If it.s not in the /boot/config.txt then you can add :

[pi4]
# Run as fast as firmware / board allows
arm_boost=1

Indeed you can't do much in retroarch of that kind.
It's probably possible to do it in the mame settings in both mame and lr-mess just like you did with making the screen wider and higher within the slider options.
I tested this too and it worked for me also and it's saved afterwards to the default mame fmtmarty.cfg config file :

/opt/retropie/configs/fmtmarty/mame/fmtmarty.cfg
/opt/retropie/configs/fmtmarty/lr-mess/fmtmarty.cfg

With earlier versions I think these slider options could not be saved but it seems it works now so probably it will for the cpu under/overclock too.

If you want to do it per game, then you have to use a loader line with game-specific, then the a config will be written in :

/opt/retropie/configs/fmtmarty/mame/<GAMENAME>/fmtmarty.cfg
/opt/retropie/configs/fmtmarty/lr-mess/<GAMENAME>/fmtmarty.cfg

This makes me wonder if some of the other games I tested that didn't work would work with the 4mb core.

It probably will.
It would be nice if you could make a list of the games you tested.
It would be good to place a list in some static place like google-drive or github so we can refer to it.

@Folly Thanks, I'll look into this! I am running a pretty gentle overclock already on a 2gb pi4.

bbilford83

@Folly I think I actually made it work out ok with Retroarch options files. I set the system cpu overclock to 100% but then created options files for each game and tested underclocking until I thought performance was best. For pretty much everything I was able to get it pretty solid except Mahou Daisakusen... that will run with the 4mb ram but it runs like garbage at any underclock. But the 4mb ram does get SSSF2 running well!

I already had the idea of saying what games I got running and my recommended overclock for each - I could put it in a list in whatever format you think makes sense and add it to the google drive share I made earlier for the Konami/Tiger mappings. It actually creates .opt files for each game for the underclock, so I could even just share those so they could just be dropped in the right folder, but I think probably it will vary for different folks if they aren't overclocking their pi, no?

Thanks for all your help with this, hopefully I can contribute a bit with my results too.

OK, actually, this should work. Here is a google drive link with 37 .opt files. If they go in retropie\configs\all\retroarch\config\MAME, that should make them automatically work for games installed to fmtmarty. And you can see the list of 37 games I have working on my system there, with the underclock for each one that I'm using in the opt file. Note though, these are only the games I think are playable in English without losing much at all, and also that you can play with a gamepad. For example, Lemmings plays great if you manually change the input to be a mouse, but I don't want to keep anything that requires that so it's not in there. A bunch of the games require a keyboard :(. I get that people did use keyboards and mice with the Marty but I really want to keep my build only as "consoles" do I don't have those on mine.

Alltynex and SSF2 require the 4mb install to load, and a few of the games require you to manually load either the disk or the CD and then sometimes restart the emulator. I am hoping when you are done with your vacation, @Folly, you might still give me a push in the right direction in figuring out a way to make that autoload.

Also, some of the games do boot into the FMT desktop and you have to double-click an icon. Not sure if there's any way to avoid that.

Cheers!

I think your link with opt files gives a good list of games that can work with lr-mess.
Also, it's probably something that can be shared :-)

I tried a few things, sadly I could not make it work like I hoped.
I am running into boundaries.

The solution/idea, of me, was to make the disk filename like this :
<gamename.cue>.mfi

In that way I could use the variable %ROM% in the loader line twice because we can only select one file in emulationstation and we need the whole path of the files in the loader line, it would become something like this :
-flop %ROM%.mfi -cdrm %ROM%
Resulting in :
-flop /<PATH>/<gamename.cue>.mfi -cdrm /<PATH>/<gamename.cue>

Though this solution doesn't work for lr-mess because when the info inside the %ROM% variable is inserted in the loader line it will add double-quotes around the path/filename that is loaded to make sure filenames with spaces can be loaded, like this :
-cdrm "/<PATH>/<gamename.cue>"

Obviously, when I use it also for the disk filename, one double-quote becomes before .mfi :
-flop "/<PATH>/<gamename.cue>".mfi -cdrm "/<PATH>/<gamename.cue>"

Sadly, the result is a non working loader for lr-mess.
So basically we are stuck for now.

@Folly Thank you very much for trying! I have been trying to dig around because I saw some people trying to get the games that boot into the marty menu to boot directly into the game, but so far I haven't found anything useful. At least they are working with a few extra steps, and it's only for a few games.

I also realized probably it's possible to "cheat" and use the fmtowns 6mb emulator to run some games that aren't working even in the 4mb marty, like Mahou Daisakusen or Samurai Spirits. For now I am leaving them off because I'd rather have it actually be a "Marty" system but if someone else isn't so picky they might want to try that.

@bbilford83

Can you put your opt files in a directory structure, so I can downloadd all in one zip file ?
Then I can add them to my repository here :
https://github.com/FollyMaddy/RetroPie-Share/tree/main/00-retroarch-00/config

If you want you can open a new thread in "general-discussion-and-gaming" so we can discuss the basics of :

bash
retropie
mame
github
add-mamedev-systems

If so you might want to reserve the first 6 - 10 posts for some summaries.

bbilford83

@Folly Done! Though FYI I think you can download a bunch of files as a zip on google drive if you just highlight them all and then click download. But I agree this is easier.

bbilford83

@Folly Hah I confess that sounds a bit advanced for me but I will probably give it a shot after I dig around a bit more :). Thanks!

@bbilford83 Does Bubble Bobble or TDF Kaijuu Daikussen work with FMTowns?

duglor

@bbilford83 Is there a complete list of games that work with lr-mess-fmtowns?

Folly

@duglor

Here you will find the mame hash tables (software lists) :
https://github.com/mamedev/mame/tree/master/hash

Look for the files fmtowns_xxxxxxx.xml.
In there you can find the supported and the non-supported software.

Remember lr-mess is the retroarch libretro core of mame running non-arcade systems.
Therefor the hash tables also apply to lr-mess.

Both are working for me. I have them converted to .chd files.

@testudo I'm still working on this. I'll let you know when i figure it all out. I don't wish for help yet. :D

@DTEAM @Folly Hello. I have decided to take a stab at this one and unfortunately like others, can't get these to launch. It returns to ES every time.

I have followed the instructions at the start of this post (even though it is a few years old). I have a RP4 with my own custom image.

I have galaxy force ii (japan).chd in the roms/fmtmarty folder.
I have gforce2.zip in the roms/fmtmarty folder
Inside the gforce2.zip is a blank text file named gforce2.
Inside the bios folder is fmtmarty.7z and is 1,162,579 bytes size and 1,163,264 bytes on disk. (It's not 1,163,004 bytes. I can't seem to find one that is).
I have fmtowns_cd.xml in the bios/mame/hash folder
In the fmtowns_cd.xml, the software name is gforce2 and the disk name is galaxy force ii (japan)
I made the changes to the es_system.cfg, emulators.cfg and retroarch.cfg in the configs/fmtmarty folder

Below is my runcommand.log
