Operation Thunderbolt

This is a near final prototype of Operation Thunderbolt. By: Evan G Last updated: July 3, 2021

This prototype is part of a collection of loose EPROMs recovered by the Video Game History Foundation on behalf of an anonymous collector. This lot contained prototypes from various systems including Game Boy, Mega Drive/Genesis, SNES, Game Gear, 32X, NES, Turbo-Grafx 16, Atari XE and Master System. The prototypes for other systems will be released on other sites, such as Hidden Palace and SMS Power.

This prototype appears to be near final. I couldn't get it to work in SNES9x, despite hacking the internal header to have the same mapping as the final version of the game. The unmodified prototype runs fine in bsnes. A cursory play of the first part of the game did not reveal any noticeable differences compared to the final version of the game. I suspect that the end game credits have a slight change with the copyright, at least by what I found in the binary:

Prototype:

@ TAITO CORPORATION 1994           ALL RIGHTS RESERVED

Final:

@ TAITO 1994                LICENSED BY NINTENDO
