Not sure, Ive gotten UAE4ALL working and running R-Type without any problems. I have my kickstart ROM in the same folder as my RTYPE.ADF – but not withstanding that the Emulator should at least load up to the GUI. Is there some kind of output log inside the emulator folder you could take a look at??
Does it drop you back to the menu or just lock up the screen?
Enjoying RetroPie R3 using Pi3 and IPAC-2. Happ Controls and Trackball in a custom Bartop with a VGA 4:3 monitor. Primarily used for MAME with a little UAE thrown in.
