ASCII Corporation always had funky deals with big video game companies; they seemed to have full access to OEM (Original Equipment Manufacturer) parts, and they always output very high quality controllers, on par with the originals. So when they were tasked with making a controller for Phantasy Star Online with a functioning keyboard, they did just that. This controller share the same internals and buttons as the original, a great controller that deserves its own section as a “second party” accessory.
