Frogger 2 Motherload Lot

In 2022, a massive development archive for Frogger 2: Swampy's Revenge was acquired by user Kneesnap. The lot contained documents, prototypes, source code, early FMV, music, and much more. Shortly after, the Game Boy Color version of the source code was obtained by Kneesnap. Shortly after this, several other game archives from Blitz Games were acquired and dumped, containing essentially everything related to the development. Hundreds of discs were acquired, along with thousands of pages of documentation and many data tape backups. Currently, the development archives for Chicken Run, Frogger 2: Swampy's Revenge, and Glover (PlayStation) have been secured, with more on the way in the future. Several data tapes were included in the game archives, and due to problems with the drive being used to read the Frogger 2 backup tape, it was sent to a data recovery company which caused damage to the tape. However, Kneesnap was able to recover about 90% of the data from the tape despite the damage caused to it.

Frogger 2: Swampy's Revenge

This part of the lot contained 12 PlayStation builds, 2 Nintendo 64 builds, 7 PC builds, source code backups, documents, and many other miscellaneous backups and development archives.
