It's probably too early to think about native integration, since this is in alpha... But it would be nice to see this functionality. I don't have many gog titles so I'll wait for the final.
That's interesting, never seen one of those before. For me it's all about 360 wireless pads. I know that's not an option for you though. I just don't know much about that tech. You might be better off with some USB extension cables.
You can also disable mame by changing the 'enable mame' setting. Do a search for that in GameEx setup wizard, I don't know offhand where the option is.
That wouldn't be an issue. It's looking for mameui favorites files. I think that Playlist error may be related to your media files for the jukebox but i can't be certain...
I don't think that's going to matter much since it's just going to add an extra split into the path array. I'm more curious if game launcher mode does even support multiple rom paths at all, I've never used it before.
Knowing how it works under the hood i can personally guarantee that it is your controller, and probably specific to whatever that mod did to 'tweak' your driver. So your best bet is to uninstall the driver, stick with the native driver if possible.
I personally loathe most old controllers, unless it's the only way like with n64 most of those are uncomfortable and can be replaced with something modern. /my 2c
Love Chrome, but am forced to use all major browsers at work. I really do love Chrome though, and nP, pretty much nailed why... He just left out printer sharing.
