Hello, here are just quick answers 1. easy, just stand over the emulator folder, bring the contextual menu (white button) then make default, you must also set the option start in program 'window' (ui preference) 2. why don't you catch wide icons ? My turn : I'm modding old cab i want to be vertical only but i need a vertical gui (mame wise), idea anyone ? you can also try mamedox 1.1 as that lets you rotate the whole gui as well.
