According to this process inspection, it worked :)

I have heard about distcc but I have never looked into it in the details, I have to study it :)

@paradoxgbb thanks for reporting back verbatim. Did I get it right that the retropie provided binary does work well? (I assume yes, as the binary [1] relates to the lr-scummvm git from 2021-12-27, it runs ScummVM 2.1.1 IIRC)

[1] https://files.retropie.org.uk/binaries/buster/rpi4/kms/libretrocores/lr-scummvm.tar.gz

The diablodiab hit-and-miss results leave me somewhat unsatisfied, but I can not put research at this atm. FTR: I am on RA 1.9.7, GCC 8.3 and for me (as stated earlier) the build of 9703372cc8 runs fine on a RetroPie 4.7.19/Rpi4.

@meleu you are the best! I will test when I return from my trip!

I want to create a scriptmodule for OpenBOR to add version 6315. I see the flag rp_module_id="openbor" that makes the module visiable into script screen. To avoid confusion I want annother name like rp_module_id="openbor_6xxx but want to use the old pathes.

Now all instances of $md_id, $md_config... uses the name that is given by rp_module_id so how to change names? I can include a function strip () { }that sets internal variables to openbor but this is not good code. So how to achive this?

Again: the goal is to use one config directory and one directory that contains several versions of OpenBOR.

Besides thank you BuZz for the platforms flags, I may exclude 6xxx for rpi1.
Is there a dedicated WIKI about script modules?

yeah tried that a few days ago. It was still looking at the old path for some extra files (digital audio if i remember). I presumed the defaults are each set as full paths , instead of relative paths of the data folder.
Its also possible i did something wrong so ill try again tomorrow

@BuZz I thought maybe because nano is a linux text editor it would auto convert EOL.
But anyway, there is an option in notepad++ for EOL conversion so I've just set it to UNIX. I'll give it a try after Kodi is done importing my library.
Thanks for the help

@chapas It's not related - please open a new topic (even if you have the same problem, it's not helpful to post to the end of an old topic)
