@caver01 Thanks for responding!
caver01 "It does beg the question, so I will write it before someone else does: why not consider the libretro version of mame4all for those titles that require the bezel, since most of the work has been done for you?"
My reasons for staying with mame4all are:
I have a known good working set for mame4all
The set works great on a non-OC'ed RaspberryPi 3
I haven't managed to get any of the libretro settings to correspond to my default old iPac2. A major issue for me. I don't like to have to spend hours re-configuring if I can help it.
I like majority of the roms on my arcade cab to be listed under one menu. I know that you can use the arcade folder but lets face it re-configuring 800+ roms one at a time to work with the best emulator is a pain when mame4all just works.
That is how my mind deals with it. I would love to use the Libretro set but I haven't been able to get the key mappings right.
I was hoping that there would be a default bezel that mame4all could see and know to auto use it but I didd't think that there would be something so simple.
Thanks again!
