Per ROM configuration - Mame4all

[h3rv3]

Hi,

I am using mame4all as I run Retropie on Pi B.
I also have a rotating screen and would like to play vertical games with the screen turned to vertical.

That works fine if I change the mame4all config file and change "ror=yes" (from ror=no) but obviously that changes the screen orientation of all the games.

I am not able to have a "per rom" configuration.
As seen elsewhere, I have created a myrom.zip.cfg (were myrom is the game rom to be played in vertical) in the same folder as the roms. It is made as a copy of mame.cfg with all the parameters (with ror=yes) but that does not change anything.

Anyone has got the "per rom" settings working?
Is there another way to do this? (thinking about using a different launch command depending on the vertical games or horizontal games collections - if possible). I don't know where to start on this.

Thanks for the help.

Using Retropie 4.8 from this site on a 1B.
I don't add anything else as it is working fine other than the problem described.

If I understand what you're asking, I think you could use RetroArch overrides?

@appas I don't think mame4all is a RetroArch core though.

Per game .cfg is only for RetroArch cores, as @sleve_mcdichael mentioned.

Try adding to the main .cfg file:

romname/ror yes

and see if the configuration is applied only to the romname game.

Yes, it is not Retroarch compatible.
Tried the suggested edit to the cog file but it does not take it.

If I use the runcommand menu and changes something. A new command line is created and stored somewhere?
Maybe I could then modify this, when I was using MAME under dos the command line was taking modifiers like
mame “1942b” ror=yes to do what I’d like to do here.

I tried running mame from the command line but it says that it is not a command.

Any further thought?

Not entirely, the settings for the ROM/system are stored, but you can't create a new command from the runcommand menu.

If you find the command line switches for rotation, you can add a new 'emulator' , based on mame4all, which has the rotation parameter added. So, assuming your ROMset is in mame-mame4all folder, the emulators are set in /opt/retropie/configs/mame-mame4all/emulators.cfg:

mame4all = "/opt/retropie/emulators/mame4all/mame %BASENAME%"
default=mame4ll

Add a new entry (note: just an example)

mame4all = "/opt/retropie/emulators/mame4all/mame %BASENAME%"
mame4all-rol = "/opt/retropie/emulators/mame4all/mame %BASENAME% rol=yes"
default=mame4ll

then using the runcommand menu you can choose the (new) emulator that runs the game. The association is saved and you only have to do this once (for each game).

@mitu

Thanks a lot for the guidance, that does it.
The line for the added pseudo emulator is mame %BASENAME% -ror

I just have to do the setting for all of the vertical games.
Thanks again for the help provided in this forum.
