It would also be great if it could separate games by 4-way, 8-way, or analogue control as well. Sortinfo doesn't seem to know about all games (as far as I can tell). Would be even greater if it knew which "trackball" games really used a trackball, which had a spinner, which were light gun, which had analogue sticks, and which had normal joysticks, but which MAME insists on calling trackball for some reason (Taito games especially).
