Pro tip for anyone thinking of installing MESS

[SpudsMcToole]

@mediamogul Turns out I had several versions of AdvanceMESS already installed, according to Retropie Setup. Not a clue what to do now, though, as the install instructions I had were for lr-mess :(

[pjft]

Out of curiosity, slightly tangential, what would you be using MESS or AdvanceMESS for that other emulators don't allow for?

I never used it and never really heard a lot about it hence my question.

[SpudsMcToole]

@pjft Tons of stuff - Bally Astrocade, BBC Micro, ZX81 and quite a few more.

I think I'm going to give up early, though. Everything written about it is just completely incomprehensible gibberish. As far as I can tell I now have at least four versions of MESS successfully installed on my Pi, and not the tiniest idea how to use any of them.

[herb_fargus]

@spudsmctoole they call it MESS for a reason ;)

[mediamogul]

@spudsmctoole

I use it for Bally Astrocade and Fairchild Channel F. For their time, they were both very impressive systems. The version of Pac-Man for Astrovision is especially mind-blowing when you look at the other home alternatives.

[SpudsMcToole]

@mediamogul How did you get the Astrocade to work?

[mediamogul]

@SpudsMcToole

I used AdvanceMESS, which is installed alongside AdvanceMAME and I in-turn installed the Astrocade BIOS (astrocde.zip) to /home/pi/RetroPie/roms/mame-advmame/advmess/rom/. Afterwards, I createad a directory named 'astrocade' at /home/pi/RetroPie/roms/ for the ROMs and then another directory named 'astrocade' at /opt/retropie/configs/ where I copied /opt/retropie/mame-advmame/advmess.rc, so the system could have its own unique config file. Also, in /opt/retropie/configs/, I created a emulators.cfg file with the following contents:

astrocade-advmess = "/opt/retropie/emulators/advmame/bin/advmess astrocde -cfg /opt/retropie/configs/astrocade/advmess.rc -cart %ROM%"
default = "astrocade-advmess"

Finally, I edited /opt/retropie/configs/all/emulationstation/es_systems.cfg to include:

    <name>astrocade</name>
    <fullname>Bally Astrocade</fullname>
    <path>/home/pi/RetroPie/roms/astrocade</path>
    <extension>.bin .BIN</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ astrocade %ROM%</command>
    <platform>astrocade</platform>
    <theme>astrocade</theme>
  </system>

That should do it, but below I'll also include my /opt/retropie/configs/astrocade/advmess.rc as a reference. There, you'll see a few settings that refine the picture and also setup analog control for the games that need it. All in all though, it's not too dissimilar from the settings you find in AdvanceMAME.

@mediamogul Cheers for that, but it's not working for me - I get dumped straight back to the Retropie menu for every ROM, not even going through the MESS splash screens first.

I'd already figured most of it out for a couple of other systems, as noted here:

https://retropie.org.uk/forum/topic/19816/getting-control-inputs-to-work-in-advmess

...but for the Astrocade with your files above I'm not even getting as far as I did with those - the BBC and Astrovision do at least both boot to their respective systems, I just can't get any sort of input to register.

I've got every conceivable BIOS file and variant in the directory you specified, called ASTROCADE.ZIP, ASTROCDE.ZIP, ASTROCDW.ZIP, ASTRO.BIN and BIOSWHIT.BIN. I've got all the game files in .BIN format in the usual ROMS directory in a folder called ASTROCADE.

Can I just check a couple of things quickly to see if I can get to the bottom of it?

(1) When you say "in /opt/retropie/configs/, I created a emulators.cfg file with the following contents:", do you mean just in the root CONFIGS folder, or inside the CONFIGS/ASTROCADE folder? (I've tried both with no discernible difference, but it'd be good to rule it out as the possible problem source.)

(2) In the line astrocade-advmess = "/opt/retropie/emulators/advmame/bin/advmess astrocde -cfg (etc), is that spelling at the end ("astrocde" with no "a") correct? (Same again, have tried both ways but just trying to narrow things down.)

(3) When you say to put the BIOS files in /home/pi/RetroPie/roms/mame-advmame/advmess/rom/, is that right? I've been putting the other ones in /opt/retropie/configs/mame-advmame/rom. (Once again, have tried both.)

The files should be located at /opt/retropie/configs/astrocade/emulators.cfg and /opt/retropie/configs/astrocade/advmess.rc

(2)

It is spelled right there. That argument is meant to specify the driver that AdvanceMESS will use. It also means that I made a typo when referencing the BIOS name, which should be astrocde.zip. I'll correct it above.

(3)

The path that AdvanceMAME will check for its BIOS files is specified in the advmess.rc. You should check yours to see what it's set to, but I would advise the path be different than your MAME files so that it's easier to manage separately.

Which path? dir_image? dir_rom?

Otherwise I'm perplexed. I'm doing everything you say and I've got all the files where they should be and I'm still getting dumped straight back to the menu. I can't find anything different that I'm doing to what I'm doing with the BBC and Arcadia setups, but those are working except for inputs.

For clarity:

(1) I've copied your emulator.cfg file and put it in /opt/retropie/configs/astrocade/

(2) I've copied your advmess.rc file and put it in the same folder.

(3) I've copied your lines for es_systems.cfg and added them into mine.

(4) I've got astrocde.zip, containing astro.bin, in /opt/retropie/configs/mame-advmame/rom (and also in /home/pi/RetroPie/roms/mame-advmame/advmess/rom)

(5) I've got my game ROMs as unzipped BIN files in /home/pi/RetroPie/roms/astrocade

But I don't even get as far as the MESS warning screens.

dir_rom

But I don't even get as far as the MESS warning screens.

After it fails to launch, post the contents of your /dev/shm/runcommand.log to pastebin.com and let's see if we can't find where the breakdown is happening.

...(almost) everything miraculously works! I have keyboard access on BBC, and it also works for the Arcadia and Astrocade (although not, bizarrely, Fairchild Channel F).

The only tiny problem left with the BBC is that because Tab is a key on the BBC keyboard, MESS doesn't recognise it for accessing the menu, and I can't figure out how to fix it because the keyboard map code is all incomprehensible bollocks like this:

input_map[key_tab] joystick_button[0079_0006_3,1]

Which is annoying, because if I could figure out the maps I could either enable Tab and set controls via the menu, or just set the joystick directly in the RC file to Z, X, /, : and Return and take care of about 90% of BBC games straight away.

(I've tried pasting in the line from the Astrocade RC file after I've mapped Tab to a joystick button, which is this:

input_map[ui_configure] keyboard[0,tab] or joystick_button[0079_0011_2,7]

but that doesn't seem to do anything in the BBC file.)

But yeah, otherwise that RC file is the Rosetta Stone and I have no clue why.

You might try something like:

input_map[key_tab] keyboard[0,tab]
input_map[ui_configure] keyboard[0,lalt] keyboard[0,tab] or keyboard[0,ralt] keyboard[0,tab]

In theory that would allow the BBC environment to use the 'Tab' key as its own, while the config menu would be invoked by either 'LeftAlt+Tab' or 'RightAlt+Tab'.

[SpudsMcToole]

@mediamogul Hmm, nope. Adding those lines has no discernible effect - pressing either Alt with Tab just acts like a normal BBC tab.

[A Former User]

I would like to thank mediamogul. Those Astrocade instructions worked perferct.
Just one thing to add to the advmess.rc, this for joystick support.
Scroll down to these lines and make sure they look like so.

input_map[p1_up] auto
input_map[p1_down] auto
input_map[p1_left] auto
input_map[p1_right] auto
input_map[p1_button1] auto
input_map[p1_button2] auto
input_map[p1_button3] auto
input_map[p1_button4] auto
input_map[p1_button5] auto
input_map[p1_button6] auto
input_map[p1_button7] auto
input_map[p1_button8] auto
input_map[p1_button9] auto
input_map[p1_button10] auto
input_map[p1_start] auto
input_map[p1_select] auto

That should work for whatever controller you are using for player 1.
One thing that I noticed was that the actual emulation wasn't very good. Lots of flickering, and often garbled sprites can be seen ,on some games, at the top of the screen. The sound was also a bit crackly, popping, and other weird sounds. I used the same Advmess as the original instruction, so perhaps a newer version has many fixes.
Off to try BBC emulation, and a few other systems.

Ha! Well, that was me assuming that 'Alt' wasn't used in the BBC environment, but if it is, it would just put you back at square one. I've run into this before with other emulated computer systems that map the majority of the keyboard. While there might be a more elegant solution out there, I ended up mapping keys for emulator functions that weren't used in the emulated environment. Normally, I'd say to open up the options menu to discover which keys aren't already being used, but in your case you can't open up the options menu to check. If your physical keyboard has media controls, I doubt they would be in use here. For example, you might try using:

input_map[ui_configure] keyboard[0,playpause]

@John_RM_70

That should work for whatever controller you are using for player 1.

Those are indeed likely to be the sanest default settings. One word of warning however, is that when set to 'auto', AdvanceMAME/MESS will grab whatever controller is assigned by the OS as js0 and js1 for players one and two respectively and so on down the line. Seeing as how this assignment often varies between sessions, it can create issues with setups that require the player controls to remain constant.

Sadly my keyboard is a basic one with nothing like that. But the BBC doesn't have an Alt key, so goodness knows what's going on.

I've tried everything I can think of in terms of editing the RC file manually, both trying to get the menus up and trying to hardcode the joystick to keys, especially around these lines:

input_map[p1_up] joystick_digital[0079_0006_3,0,0,0] or keyboard[0,up]
input_map[p1_down] joystick_digital[0079_0006_3,0,0,1] or keyboard[0,down]
input_map[p1_left] joystick_digital[0079_0006_3,0,1,1] or keyboard[0,left]
input_map[p1_right] joystick_digital[0079_0006_3,0,1,0] or keyboard[0,right]
input_map[p1_start] joystick_button[0079_0006_3,7] or keyboard[0,1]
input_map[p1_select] joystick_button[0079_0006_3,7] or keyboard[0,5]

but nothing has any effect. I know people HAVE managed to get the MESS menu up in the BBC emulator, but Lord knows how they did it.

Still, it may be using the 'Alt' key as a stand-in for some other key. If you could find one key that isn't being used, you should be able to access the menu. Below is a list of all the available options.

EDIT: Anyone know what the 'coffee' key is?

[A Former User]

Got it working great.
Followed Spud11's post, and partly mediamogul's astrocade posts.
Just fired up Planetoid, looks good.
Tried a few bbc disk commands, and they too worked - *cat, *!boot , etc....
It's 2am here, so off to bed. Tomorrow, I will test a real BBC Master, alongside the Pi, and post some screens from the same games.
Whats weird is that my BBC Master has a Pi Zero inside it, running as a co-pro, along with usb and a CF HD. Amazing what people are doing with the Pi, even adding it to it's big old granddad, the BBC.

Very nice! I look forward to seeing how it holds up.
