I’ve seen that a MESS 2014 core is now available for download through Retroarch’s core updater and I gave it a try. But when I open the core and run it, the screen remains black and nothing happens. I try to open the OSD menu through the L2 button (which works in MAME cores) but nothing.
I want to try some apple II+ ans MSX games through this core but until now I have no idea on how to use this core to run such systems/games. How am I supposed to run a MSX game or an Apple II+ game here? Any tips are welcome
