According to pcedaisakusen, japanese retail titles:
CD: 121
SCD: 282
Yes, but things get more interesting when we chart those 121 CD (and, if possible, the SCD) releases by MONTH and see how the transition from CD ----> SCD unfolded.
Also, just for my own curiosity, it would be interesting to have a breakdown by publisher...to see how different companies handled it.
You know, you can do this sort of filtering in the PC-Engine Hyper Catalogue CDs.
(I don't know of any automated way to do it on computer, though.)
Ha!
I have some Hyper Catalog discs, too, but...I wish I could get the raw data.
I think pcecp.com was built by dumping the data from the "final" (theoretically most up-to-date) Hyper Catalog disc...
I wonder...if I sort by format (CD, SCD, etc) at pcedaikusen, I could get 2-4 independent timelines, then overlap them.
CD--> filter by year
SCD--> filter by year
Etc.
If I wasn't on my phone, I'd like to try this out.
