Hidden Palace publishes recovered Sega Technical Institute game prototypes and Segapede source archive

On 31 October 2026 preservation researchers at Hidden Palace shared recovered Sega Technical Institute prototype materials originally dating to 1991–1994, including Jester, B-Bomb, Treasure Tails and Segapede source-derived material with a documented build pathway. This is a public archival release of historically produced artifacts, not their original game-creation event; reconstructed ROM execution, artifact hashes and cross-emulator compatibility have not been independently verified in this review.
