Oh dear, I do believe I have the vapors. This page contains content that is not safe for work or other locations with the potential for personal embarrassment. Such as: Two early movie posters featuring nude women.

This game/console's online features are no longer supported. While this game/console's online features were once accessible, they are no longer officially supported and online-exclusive features may be documented as now-unseen content.

This needs some investigation. Discuss ideas and findings on the talk page.

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

This page sucks. If you could make it suck less, that would be awesome. Specifically: All of the information is cobbled together from multiple different versions of the game, and it's presented mostly without any context. What would probably help the page most is a complete rearrangement.

To do: There is SO much that needs work here that it cannot be understated. There are many changes that happened between the original Japanese release, the international releases, and even De La JSR. All of those changes need to be documented. On top of that, there are also many changes in the 2012 re-release that need documenting. Here are just a few things that need to be fleshed out: Almost everything in these videos are undocumented. A few of these details from these videos are documented below, but you'll need to see the videos for full context/more information. The katakana on the character designs in the 2012 re-release only match their original Japanese names rather than their localized ones. Get visual comparisons. At some point in the past, the Steam version of the game was updated to remove references to the Red Cross. Apparently those changes were not reflected in all versions, with the Xbox 360 version still using the Red Cross sign. See if anything else was updated on the Steam version, and check if any other platforms are also missing these changes. And get visual comparisons for all of this. Character names and designs differ between almost every version of the Dreamcast game. Cover all of them. Cover the differences between each version of the 2012 release. In the 2012 version, almost all of the graffiti had to be changed for licensing reasons. Sega held a graffiti contest where the winners would have their work featured in the 2012 port, and these are the works that replaced the licensed ones from the original game. Get comparisons for all of these. Get visual comparisons for everything already here that needs it. Move everything related to the 2012 port to its own page, and merge the iOS page into that. Three prototypes (the E3 build dated April 28, 2000, the American build dated August 22, 2000, and the European build dated October 3, 2000) exist online. Document them.

Everywhere else: JET SET RADIOOOOOOOOOOOOOO!

America: JET GRIND RADIO!

(The original JET SET RADIOOOOOOOOOOOOOO! experience has since been recreated on modern consoles, including iOS. This time the American localizers didn't crash the party.)

Unused Dialogue This is Tokyo bandit radio, Jet Set Radio!

Unused Graphics

Characters

DEMO14	DEMO28	Final

An early texture of Beat is found in DEMO14.AFS. The name on his T-shirt says "Ereki", which is short for "electricity", thus the lightning bolt and the light bulb. His headphones also look slightly different and there are knuckle holes in his gloves. The graphic for his wrist computer thing also hadn't been implemented yet. On another note, you never actually see him without his glasses, so the eyes are unused. DEMO28 is a bit closer to the final design here, but still very different looking. His headphones and gloves still hadn't been changed, and his wrist gadget is still missing.

Early	Final

This texture of Gum is also found in the DEMO28 file. Just some minor tweaking here. Her wrist device also hadn't been implemented yet.

Early	Final (Japan)

This early texture of Corn/Tab is also found in the DEMO28 file. The katakana symbol for "ko" is written on his cheek, and his shirt shows the katakana symbol for "su." The line on his hat was changed from green to orange. And, of course, his wrist device wasn't implemented yet.

The Garage

Early	Final

This photo of Combo, Cube, and Coin is used as a character select graphic when you first play Chapter 2. The early/placeholder graphic on the left can be found in the file "GARAGE.AFS", while the final version can be found in "U_GARAGE.AFS". It looks like Coin, the center character who was kidnapped by the Golden Rhinos, went through a bit of a design change. The texture below the picture is of the piece of tape that holds the photo up.

This texture is found in the file "MARKEDIT.AFS". At the bottom are unused icons with early character names on them.

The names read as follow (final names in parenthesis): Cone (Corn/Tab?), Reco (Cube), Gum, Poison Jam, Combo, Nattsu (Sugar/Piranha), Code (Soda/Slate), Love Shockers, Bis (Mew in the west), Pinch (???), Noise 66 (Noise Tanks), Yoyo, Beat.

Shibuya-cho

Early	Final

This early restaurant ad can be found in the files DEMO13, DEMO14, DEMO21, DEMO22, and DEMO28. The earlier version is an obvious parody of Burger King.

Early	Final

Additionally, this early texture for the restaurant itself can be found in DEMO21, DEMO22, and DEMO28.

Early	Final

Yet another instance of the change. The early texture can be found in DEMO03, DEMO04, DEMO08, DEMO13, DEMO14, DEMO21, and DEMO25.

Early	Final

This billboard for watchmaker Swatch, specifically advertising their .beat time system (yes, this was a real thing they tried), can be found in the files DEMO13 and DEMO25. Since this is the only billboard in the game advertising an actual real life product, it seems an in-game advertising deal fell through. Interestingly, Sega would later go on to use the aforementioned .beat time system in the original Phantasy Star Online.

Bizarrely, the SEGA licensed anime Hi-sCool! Seha Girls uses the early image in its episode about Jet Set Radio, although the Swatch logo was replaced with a generic "Watch" logo for copyright reasons. Considering the fact the episode aired over 14 years after the game's release, it appears the animators accidentally used an earlier model of one of the game's levels.

Benten-cho

Early	Final

This early movie poster can be found in the files DEMO17, DEMO18, DEMO19, and DEMO20. It is displayed in the center circle of Benten-cho with several other posters. The early version was a blatant ripoff of promo artwork for The New Batman Adventures. (Plus the name they chose was already copyrighted by a movie studio.)

Early	Final

These two porno movie posters can also be found in the files DEMO17 through DEMO20. They too were meant to be displayed in Benten-cho's center circle. The assumed "finalized" posters are the only two posters that don't appear in the DEMO files.

These images are in the file "instructiontxr.bin", which is found inside the files "SEGALOGO.AFS" and also "U_SEGALOGO.AFS". These graphics appeared before an early demo version of the game. Notice the different designs of the green arrows and timer font.

This image is found in the file "PROMO.AFS". It shows an early title logo concept for the game. The text below (2000年春発売予定) translates to "Planned for a Spring 2000 release".

Unused Music

The game's original Japanese release included the song "Dunny Boy Williamson Show" by Deavid Soul. The track does not play in any other release of the game; however, the North American version still contains the song's files in the "JETRADIO" folder, rendering them unused.

DUNNY_F

The first portion of the track, which, in the Japanese release, plays at the beginning of Stage 2, Love Trap.

DUNNY_M

The second portion of the song. Interestingly, this song's main files are appended with the letters F, M, and R instead of the game's usual M1, M2, and M3.

DUNNY_R

The third and final portion of the main song.

DUN_SJ1

Nearly identical to DUNNY_R above, with the only difference being a small clip of Professor K at the very end.

DUN_EVE1

This file bridges the ending of Dunny Boy Williamson Show and the beginning of Everybody Jump Around.

DUN_THA1

The last unused music file is a transition between Dunny Boy Williamson Show and That's Enough.
