I'm not working on this atm... it's currently too nice outside, but people have been very helpful about sending me info and I've been running across stuff myself.
The Japanese version of 2006 (called plain old Outrun 2 SP over there) had some different sound track selections. 4 Unique songs in total and they are all pretty awesome.
Included are "SP Remix" versions of Passing Breeze, Splash Wave and Rush A Difficulty, all of which, seem oddly western sounding for a Japan only release.
Also an original track titled "Lift You Up!" which, despite it's sweet-sounding title, is actually more like a Sega-fied Metallica song was included.
All of these songs are included in the 20th anniversary Outrun soundtrack, which can be listened to here:
Oddly enough, there was more than enough room on the PC dvd to include these songs. In the sprite sheet that contains all the song title sprites, there are even the "tracks" TBD 01 - TDB 06 (to be determined) which makes me think that these songs along with two more were supposed to be added to the pc version. There's no code left unfortunately.
But in my app I'll be taking control of the music (optionally of course) so we can add them back in.
Also on the sprite/uncensor front..... I ripped some of Clarissa's sprites from the PS2 version the hard way. While the menu sprites are hack jobs, apparently they did do new renders for the expression sprites. Unfortunately they used an inferior base model. In the ps2 version she has actual curves on her elbows, more realistic hair, ect.... But the ps2 sprites are also half the resolution, so they look slightly fuzzy. I'm not sure which set would be best in this case.
*edit* Also Holly wears a totally different outfit. It's more of a Jeans and T-shirt deal as opposed to her more dressy outfit in the US version.
Uncensoring the models has been equally difficult. That minor hole in the "ending" model is probably fixable, but the one for the in-game model is proving troublesome. Even more frustrating is the fact that the uncensored models ARE included with the game, but I can't seem to swap them out due to incompatible bones. The uncensored models are also referenced by the game code, so I've got to wonder how they are used.
Perhaps some of our non-English friends can clarify.... is Clarissa's model (not the sprites) uncensored when running the game on a non-English pc? I've tried changing the language settings, but to no effect.
Also I made a proper horn icon, that looks much better as well as ripping the gas pedal icon. I'll post some pics of all this new stuff once I come back to the project.
