How do I change my my xroar config options for coco

Oldguy

How do I use a xroar.conf file with Retropie/Emulation Station. I want to change my config to simulate different Coco configs.

System
Raspberry 3B+
Retropie 4.4.4 downloaded from retropie page
Have already reinstalled xroar from source
Also I have a good recommended power supply

I cannot figure how to get retropie to read a xroar.config when launching from emulationstation. If possible what director does it need to sit or if not how do I give options.
Also, any ideas on why my games work one time and then the next run will drop to the prompt and not run. Very frustrating.

Thanks.

RetroPie's xroar adds 2 machine types which can be selected from the Runcommand launch menu - cocous and coco, but it doesn't set a specific config file.
You can use the default Xroar configuration file to add your configuration (/home/pi/./xroar/xroar.conf) and if you wish to have different machine profiles selectable, then you can add your arguments to the RetroPie's Runcommand set of emulators or add a new emulator entry with your command line switches, in /opt/retropie/configs/coco/emulators.cfg.

Thanks for the help but I do not understand the /home/pi/./xroar/xroar.conf part. What is the . in the middle mean as I do not have such a director. I cannot cd to /home/pi/./xroar to create the xroar.conf. I am sure this is simple but I have not used unix in a long time.

@Oldguy .xroar is the name of a folder, the . means is a 'hidden' folder. It's not created by default, but you can create it manually. Alternatively, create your xroar.conf directly in /home/pi/ and then edit the emulators.cfg file and add the -c /home/pi/xroar.conf argument to the xroar command lines to read its configuration from your file.

Thanks so much. This works. Two additional questions. First, can I put comments in a emulators.cfg file with a # at the beginning of a line if not how? Second, any guess as to why with the default config that one time games will work and other times they do not start and it drops to the ok> prompt? Very frustrating.

Yes, you can.

I'm not sure, but I can give it a try to see if I can reproduce it. Do you have an example ROM that I could maybe try ?

This helped and I believe solved the problem once I tweaked my config options. Thanks so much.
