This should be really simple, but alas, it only seems to work under mame-libretro, where as advmame and mame4all keep the dials assigned to joypad direction no matter how many times you re-assign the buttons.
How do I resolve this? Mame-libretro plays some of the dial games, but not alland I’d really like to see this work, but apparently two of the cores still have some bugs.
I just noticed that when ever I leave mame-libretro, that I have to re-assing the buttons each and every time.
The other two mame emulators do not have this problem.
