I'm PSinh (previously known as SFamiCominh).
My project is to collect and list all Playstation 1 hibaihin.
As a secondary goal, I also grab softwares that could only be purchased out of the ordinary circuits as well as "corrected versions" or rare variations.
What are PS1 hibaihin 非売品 ?
Hibaihin include all "Not for sale" softwares (presents, demos, promotional/bonus contents, utility tools...etc), released on Japanese Playstation. Sony labelled them with specific serials (details here).
There exist many kinds of them, from simple demos (taikenban) to unexpected, obscure CDs... I've tried to classify them in comprehensive categories.
Feel free to take a look ;)
Important notice : please note that I don't collect prototypes or unreleased titles because they have no specific serials.
Games with a "Not for sale" sticker on the back are also excluded because they are the very same softwares as their retail counterparts (serials are the same, there is an identical barcode too...). The only physical difference is that a "sample" mention is printed around the center holes of the CDs.
These are full-game copies which were given to media in order them to make reviews. The goal here was to prevent resale. They are no real hibaihin.
Most stickers are orange with a serial. On some early games, they can be in different colours and can have no serial at all...
