While the preservationists over at Hidden Palace are still working on further updates to Project Deluge, their project that encompasses dumping hundreds of previously unknown video game betas and prototypes, they've taken a short break from it. That doesn't mean they're not still working on bringing fun pieces of gaming history to light, though, as they've released five different prototypes for the Crash Bandicoot series. Ranging from Crash 2: Cortex Strikes Back, Crash 3: Warped, and Crash Team Racing, these PlayStation 1 prototypes are E3 builds and unfinished versions of each of the games. Hidden Palace has documented the differences between the betas and the final releases, showing off video footage of the builds in action. For example, you can find that the Aug 26th build of Crash 3--dated two months prior to the official release--has a track that went unused, along with various minor relic and text changes. The Crash Team Racing prototype even requires a dongle to be used on actual PS1 consoles, and thankfully Hidden Palace has provided patches that bypass the requirement.
