I've noticed that some games (i.e Bubble Bobble) don't save the hi score by default. To get around this, I have enabled "Automatic save/restore" under State/Playback Options. However, this doesn't seem to apply to Hellfire. Is this a bug as I would have thought this should have worked for every game. If not, is there anything else that can be done to improve hi score support?
Also, whilst we are around this area, could someone explain what "Bilinear Support" and "Burn-in" do? I should also mention that I'm using the Ubuntu version on Mame (latest is 0.189) if that makes any difference.
