Editing TurboGrafx-16 (section)

===Arcade Card===
On March 12, 1994, NEC introduced a third upgrade known as the {{nihongo|''Arcade Card''|アーケードカード|Ākēdo Kādo}}, which increases the amount of onboard RAM of the Super CD-ROM² System to 2MB. This upgrade was released in two models: the ''Arcade Card Duo'', designed for PC Engine consoles already equipped with the Super CD-ROM² System, and the ''Arcade Card Pro'', a model for the original CD-ROM² System that combines the functionalities of the Super System Card and Arcade Card Duo into one. The first games for this add-on were ports of the [[Neo-Geo]] fighting games ''[[Fatal Fury 2]]'' and ''[[Art of Fighting]]''. Ports of ''[[World Heroes 2]]'' and ''[[Fatal Fury Special]]'' were later released for this card, along with several original games released under the ''Arcade CD-ROM²'' standard. By this point, support for both the TurboGrafx-16 and Turbo Duo was already waning in North America; thus, no North American version of either Arcade Card was produced, though a Japanese Arcade Card can still be used on a North American console through a HuCard converter.
