Hello everybody. I am new to launchbox and i am using the latest free version. I managed to add some SEGA model 2 games and run just fine in full screen also. My problem is that when i run SEGA model 2 through launchbox, i can't edit controls for each game (as it runs in full screen and if i press esc it will go back to launchbox). So how can i edit and save somehow the controls for each game on Sega model 2 emulator? Is there a way? Maybe writing something in EMULATOR.INI? Thanks in advance!
