Good morning! I had a go at this just now before leaving for work... I think you can make it work, but it needs something extra. When you bring up the context menu for a console, you have options to to change the launcher, etc. I'm playing with Sega Genesis right now, since it's the console I'm most familiar with. When you choose the launcher, it gives you the list of available cores and obviously for me I'd want to pick the picodrive one. But this looks like it's a pre-defined setup. There's no way to actually change the command line. Would it be possible to have another option in the list called maybe "Custom" where you can actually just input your own command line? For instance, to make Picodrive work with the custom controller config, my command would be:

Code:

retroarch.start picodrive picodrive_libretro.cfg /storage/roms/"rom name"

So I would assume you would replace "rom name" with %rom% or whatever (and point the path to the right location). Would this be doable? I think rather than building a brand new custom menu to select it from a list, the ability to add a CUSTOM would work best. Of course, you'd want to have that save to a new file for each console.

Thanks for an awesome addon. I just hope to make it work for me on the RPi2! See ya after work lol.

Yeah, that can be done. Like you said, the addon comes with pre-defined launch commands, but you can add your own.
See the wiki here. You'll need to edit the xml file "external_command_database.xml" and just paste the command you listed above in with the title you want. Then when you choose your launcher, your command with the title you list should show up and you can select it. All the addon does in this case is write that command line to the xml for use with all games in the list.
Keep in mind though that the path to "retroarch.start" and probably the config file needs to be defined explicitly with the path included. I'll take a look, I haven't actually set this up on RPi for external launching but it should work without a problem. If you've got a list of commands that look like they'd be useful for everyone please let me know and I'll include them in the addon directly.

I also like the idea of having an option for the user just to input whatever command they like, I'll add that to my list of things to do. For now though, you'll have to edit the xml manually. Let me know if you get this working and you have some helpful info to add to the wiki for RPi.
