The early and late versions of Michael Jackson's Moonwalker for the Mega Drive.

First of all, the rumor is that "the early version plays Thriller, but the late version doesn't."

I will explain this in detail!

The rumor mentioned above is,

"Only if you perform a dance attack on stage 3 and 5-3 of the early version, the phrase before the chorus of Thriller plays. On stage 3 of the late version, if you perform a dance attack, the same BGM as the stage BGM, The "Another Part of me" phrase plays"

For comparison, the white Michael on videos 1 is the early version, and the red Michael on video 2 is the later version!

I looked at the internal data of these early and later versions and the checksums were different, so I think they are different versions.

However, the title display on Romchacker was the same for both.

...Well, it's a popular title and there must have been a lot of stuff extracted in the early days of the Internet, so I think most of the ones registered have mismatched labels.

...Actually, Europe was released six months after North America and Japan. I don't know if there are early and late versions in the North American version of the actual ROM, so please forgive me for that.

The way to tell the difference is the sticker on the back of the cartridge, as shown in the first photo and video.

The contents of the manual are the same, but the position of the stapler is slightly different...?

But it's just for reference, since you can't tell if these are swapped out.

If the case has a claw, it may be the later version, but you can't tell if it's swapped out either. Hmm

So we can't listen to Thriller?

...Actually, 6 years ago, a ROM under development was miraculously discovered, and Thriller, which was supposed to be implemented, was discovered.

Thats is the only (and unofficial) way to have it in the game.
