People who were still using a PC Engine console with the original CD-ROMВІ System add-on could opt for the Arcade Card Pro instead, which essentially combines the functionalities of the Arcade Card Duo and the Super System Card into one by adding the 16-Megabits of D-RAM from the former on the top of the 192kB of added buffer RAM and BIOS update from the latter. Unlike previous System Cards, the change was purely on a hardware level and there was no BIOS update this time, keeping it strictly on Version 3.0. The Arcade Card Duo, designed for PC Engine consoles equipped with the Super CD-ROMВІ, adds 16-Megabits of D-RAM on top of the 256kB of buffer RAM within the hardware.

It was initially available built-in with the PC Engine Duo, a model of the console with an integrated CD drive, but was quickly offered as an upgrade to owners of the original CD-ROMВІ System in the form of the Super System Card, and later as an updated model of the add-on itself known as the Super CD-ROMВІ unit. The Version 3.0 BIOS was launched in Japan in 1991.
