So that's what this does...

It seemed, to me anyways, that was uncertainty on the old AIJ forums about whether or not the bytes that follow the song's **DISPLAYED** BPM in the song definition - from Taren's notes - actually influence position on the songwheel or not.

Guess this proves those bytes play a role in where the song appears on the songwheel..

In case you think this is just an altered screenshot, or Stepmania, etc, a Youtube video:

How is this hacked? (or, "What is different?")
On MAX2 JP, Burning Heat! (3 Option MIX) is supposed to be the 3rd down from the Roulette selection, in the green category.   This song appears in the PURPLE grouping only in the ARCADE version of MAX2.

How was this done successfully?
I went into the song definition for Burning Heat, and the one for Afronova (from Nonstop Megamix), and swapped the few bytes that follow the song's BPM - giving Burning Heat Afronova's, and vice-versa.

Apparently altering the position in of itself will not work well if at all - and if you intend to swap slots, you actually need to swap the position information for both songs - not just overwrite the information for the song you want to re-locate.
