Nope still getting this. I added "Demul Arcade" as the platform from scratch and everything. It's a bummer because I feel like were so close to figuring this out.
Naomi games run directly from Demul no problem. When I add them to Launchbox and try to run one I get an error as if it can't find a rom in the dc romset. I'm so lost as what to try next. As far as I know all the parameters/settings are correct.
BigBox exit hotkeys are not working when running Mugen specifically. It works on fine MAME and PS1 and Openbor but for some reason it doesn't work when trying to exit Mugen. Any help would be much appreciated.
