hello i bought the pro version of launchbox but i ran into some problems. I downloaded romsets complete with mame and neogeo but despite the bios neogeo.zip they crash and do not hook retroarch. I'm sure the romset is good because on other frontends it works and consequently also on retroarch. On neogeo I solved it by downloading the NEO.EMU paid app but as regards mame (romset 2003 plus) I can't solve otherwise.
