Talk:Jet Grind Radio (Dreamcast)

Name

We're keeping it Grind, right? I was just wondering because ever since the initial DC version, Sega has always referred to it as Jet Set Radio (that's its US title for the recent re-releases as well). WhoIAm 22:13, 18 January 2013 (EST)

I say change it, keep the original US title as a redirect, and alter the bob to put the US having an alternate title. The remake/sequel on the Xbox used set worldwide. Thecharrr 22:22, 18 January 2013 (EST)

I say keeping it as the original US Dreamcast version's name, despite it being less well-known, is more helpful for organization, because then we can refer to the Dreamcast game as "Jet Grind Radio", and the Xbox version as "Jet Set Radio" instead of "That Jet Set Radio remake or sequel or whatever-it-was for the Xbox". Besides, now we can poke fun at Sega of America for changing it on this page instead of ranting about it pointlessly in the Talk page.AquaBat 22:43, 18 January 2013 (EST)

That works too Thecharrr 22:45, 18 January 2013 (EST)

The Xbox sequel was called Jet Set Radio Future, not just Jet Set Radio. Or are we talking about the recent 360 release of this game (which also came out on several other platforms)? That version retains all the same assets of the original, so anything unused here would be unused there. Not much reason to make a page for it, unless you're comparing some of the few changes made to it. --Rabidabid 15:14, 19 January 2013 (EST)

Wait, what? They didn't upscale and / or clean all the textures in the modern ports? // Foxhack 15:38, 19 January 2013 (EST)

Guessing it was a quick port, but the textures sure have aged better than say Unreal. Thecharrr 16:06, 19 January 2013 (EST)

Yeah, the textures are all identical. Same file format and everything. As far as graphical changes go, the only major difference is that they swapped out some of the old graffiti for new ones made for a contest. I think they may have cleaned up the HUD too, but I'm not sure. --Rabidabid 16:32, 19 January 2013 (EST)

Regardless, Jet Grind Radio is Jet Grind Radio. Sure, since there's a GBA game with the same name, we have to slap a (Dreamcast) on the name, but it's still the US name and that's the conventional naming method of these pages.

Texture Ripping

Just how are you guys getting the textures out? I'm having varying amounts of success going through the files, but I'm not finding very many textures from 3D models... -LanHikariDS

It's been a while so I had to look into it again but somebody threw together a basic program that unpacks the textures. It was meant for the PC version but works with the DC version too since they use the same files. Here's the pastebin with the source code and here's the Steam thread it was posted in.

This is the process I think I used:

1. Used GDROM Explorer to dig through the GDI dump of the game and extract the AFS files.
2. AFS Explorer to open up those AFS files and extract the BIN files inside.
3. Drag and drop those BIN files into the program above to unpack the PVM files inside.
4. PVR Viewer to open those PVM files, view the PVR files inside, and convert them to PNG.

Ahhh, thank you. the BINs are what were giving me trouble. What I'm doing is extracting all the BINs and having PuyoTools convert all the textures at once -LanHikariDS

Voice lines / Demo stuff

I found unused voice line files on the Dreamcast Magazine Demo version of JSR. I don't know how to share those though, because as far as I know, there's no known way to play them outside the game. My method was to simply replace a player character's lines and hear them in game when the character jumps/gets hurt/dies/etc. I guess a recording of normal gameplay featuring these sounds would not be ideal?

I was looking for this version for the voices specifically, but maybe there's more interesting things to find, I haven't looked hard enough yet. The demo wasn't mentioned here on the wiki, but it kinda counts as something like a regional version? There's also a Dreamcast Express Japanese disc that has a promotional video of an early version of the game and a silly-looking animation of Professor K.

I think these are all important, but i'm not sure how to put it into wiki format. Since there is no information on the demo materials here, i assume it's because no one thought to check them yet. Someone, please take a look if you can. JSR demo - Google Drive There's GDI's of the discs, and extracted data of just the JSR demo version. Thank you. -java_finch

Demos typically go on prototype pages. Ideally we'd want .ogg conversions of the raw audio files. If they're just ADX files, they can be converted with foobar2000 and (I think) vgmstream. But in-game recordings could be passable. Maybe replace the background music file(s) with silence? Thanks for the upload though! I might give it a looksee. --Rabidabid (talk) 21:40, 17 December 2019 (EST)

This page is a complete mess.

Particularly the version differences section, but the game as a whole is woefully underdocumented. Even with the things that are here, you can tell that not much research went into it apart from the surface-level stuff. There's a hell of a lot of work that needs doing here. Is anyone currently working on a rewrite of this page? If not, I'm seriously considering starting. -MisterSheep (talk) 08:46, 14 October 2023 (UTC)
