Konami attempted to upgrade the original series by creating a third one. The latter's cabinets have much better audio and graphics, along with pedals. Players can even save their progress with floppy disks!
Which Control Scheme?
A proper controller is more suitable if your fingers are too big for buttons mapped to your keyboard. The Japanese PSone games are bundled with controllers similar to the cabinets' ones, while European Edit is bundled with a controller that resembles the on-screen note indicator. DualShock controllers become less comfortable on difficult notecharts. Beatmania IIDX's controllers, such as the one that the North American PS2's Beatmania is bundled with, are only officially supported in 6thMIX + CORE REMIX.
