Goemon's Great Adventure (がんばれゴエモン~でろでろ道中 オバケてんこ盛り~) (N64) - Intro in US/EU Versions
First of all I'm sorry about the inconsistent framerate and graphical glitches in the footage. I used JSemulator to record this, as while I do have Project64 and Mupen64Plus on my computer, the former always crashed every time I tried to select something in the debug menu, and I don't know how to add Gameshark codes in the latter's case.
Anyways, this video shows off something interesting I found in Goemon's Great Adventure/Mystical Ninja 2 Starring Goemon for the N64. You see, when Konami released this game outside of Japan, they removed the opening as well as the "Double Impact" cutscene that plays before the Goemon Impact bosses.
However, there is a debug menu in the game that allows you to play various story-related cutscenes, and one of them ("UTADEMO") is actually the aforementioned intro, which is still intact in the international versions! However, when the intro is accessed this way, the game's HUD will overlap most of the intro until it transitions to the Goemon Impact part at 1:07 which reveals that the subtitles weren't translated and are now a jumbled mess.
BTW, while not shown in this video, the Japanese-exclusive cutscene where Omitsu faints at the fact that Miss Impact is supposed to resemble her ("A1 OMITSU IMPACT B") is still in the international versions as well, but the text has been removed.
