Just getting back into Emulation. been out of it for 5 years. I have a probably 1.69 Mame rom set. i also downloaded a 202 rom and CHD sets. but when i try to run any rom in mameUI64 examples 1941, 1942, 1943 and digdug. The screen just locks up or goes black and nothing happens. i have to push esc to get out of it.
Not sure what i should do to get a full set of roms running.
