WTB: Crash Bandicoot prototypes for PlayStation

[Twilight]

CRASH BANDICOOT - alpha, beta, debug, preview, review etc versions for the PlayStation/PS1/PSX

I'm looking for the prototypes, alpha, beta, debug, preview, review etc versions of Crash Bandicoot and Crash Team Racing/CTR developed by Naughty Dog for the PlayStation/PSX/PS1.

Crash Bandicoot
Crash Bandicoot 2: Cortex Strikes Back
Crash Bandicoot 3: Warped
Crash Team Racing (CTR)

I'm also interested in Crash Bash so feel free to offer me any original preview/review discs with this game too.

Please do not offer any fakes or hacks and do not offer any already leaked builds on the CD-Rs which you recorded from them. If you have the original media of any already leaked builds then I'm very interested in it. Any Japanese prototypes and half-translated versions are also very welcome!

The discs may be numbered or may have the name of the reviewer on them. The stuff is really old so please don't worry about it. Any discs with uncovered confidential information like numbers or names will not be showed in the Internet. They also will not be re-sold as ISOs.
