JP DDR CS System Data Support
System Data Support
System Data Support is a feature on most Japanese Sony PlayStation and PlayStation 2 DanceDanceRevolution titles. What this feature does is unlock secret data of previous Japanese DanceDanceRevolution titles, if you have a compatible save file on your memory card. This appears in the MEMORY CARD (for PlayStation titles) or SAVE/LOAD (for PlayStation 2 titles) section in the Options menu.
Only games that give and/or receive support are listed.
