There are a couple of interesting differences between the original Japanese game and the western releases. Particularly obvious is the boot-up screen, although the Japanese version doesn't have any, the American release starts with a copyright screen and a digitized voice that says the name of the game (Space Megaforce!).
Another surprising difference is the omission of all references to the anime-style characters seen in the original game - both the pilot and the female co-pilot were removed from the option and game over screens, as well as the introduction and end sequences. As a side note, the Japanese end sequence also shows that Thi (the co-pilot) plays an important role in defeating the alien invader and this part was completely removed from the western release... The story was also heavily edited, as well as the name of the various areas and bosses. Finally, the music tracks for the bonus stages (levels 3, 6, 9 and 10) were swapped around and one track was entirely removed (well, this track does sound awfully close to several New Order's hit songs, such as 'The Perfect Kiss' or 'Fine Time', and this potential copyright infringement may explain the removal).
Finally, the voice message played each time the player collects a power-up was re-recorded for the western releases and arguably sounds better.
