PS1 Rock & Roll Racing 2 - Red Asphalt prototypes search

[Dedok179]

Hi all. I'm looking for all possible early prototypes of PS1 game Rock & Roll Racing 2 aka Red Asphalt in order to preserve the history, analyze, and also possibly add resources from these prototypes to the core of port this game on PC (in development). At the moment, there is only one prototype on the network dated June 6, 1997 (almost six months before the release of the game). But there are even earlier prototypes (from 1996 - early 1997), perhaps they are in the hands of old journalists or someone else. Maybe even somewhere on the old DevKits something was left unowned from concepts and other things. I would appreciate any information on this matter!
