Couldn't somebody just make a program that lets us edit the rabbits colours in single-player(without a new tileset for every level I mean)
It would be a beginning.

May I claim the second page in such a serious forum(except for the fake edits)?

Derby:Claim edit

As Stating i have no idea how to use this, maybe you guys will know how to use a dissassembler http://www.yoe.org/products/sparc/da.shtml
Admin, i know you guys want this, please dont delete!!!

Firstly, providing links to disassemblers is a slightly questionable practice.
Secondly, what would we do with a SPARC disassembler anyway? Jazz was only made available for x86 and macs, AFAIK.

Well, there are all sorts of games out there with mods. How could Jazz 2 be any different? We can't edit the ANIMS files YET, but that's exactly why we want the scorcecode - to do things with Jazz 2 we can't do right now. And I certainly don't want Sega to sell Sonic to us! If you've ever played FPS online you can see recognisable characters that people have made and downloaded: Sonic, Homer, Snoopy, etc online. Those franchise weren't sold out, and those people haven't been told to get those models off the websites they were on. It's just fans putting some of their other favouite characters in a new game.

Also I would hope I could make Sonic available for download so others could play as him too - or so that they could see him atleast when I play as him. Or maybe there would be a way to let others see him without them downloading it. I know it uses the local animation file - and that makes sense. I think it would work just like models work on FPS. If the server has the download and it's in use, all other players will download it automatically and see the person being that character. Just because Jazz 2 is a side-scroller doesn't mean it won't work in similar ways to how FPS work when it comes to downloads and mods.

I guess I just have a hard time believing that the animation can't be changed. Look at Duke Nukem 3D - which uses flat sprites for the characters. It doesn't exactly come with a user-friendly character editor, but you can make your own enemies or playable characters for it. Whether it always has to REPLACE existing characters, or if it ADDS them is unknown to me. I just hope we do get that sourcecode, and then we can work something out. Just let me handle the animations.

?????????

Hmmmmmm..........Nadine, I have a friend who's named Omegaxboy. He knows how to edit any animation. He used photo editor. Captures, edit, and save!

I don't think it's that simple. The animation library is compressed.

It would be cool if we could add custom chars, but even if we get the source it could take a while to figure out how to get in game.

As for the animations, if we get to that stage feel free. But I'm gonna have Skulg do some...

our own custom sprite format is zipped in multiple parts
into this anims.j2a file

pretty darn difficult to extract, again, you're going to need the source

-arjan

that's why anyone can't edit it

What does the source code do any way?

It is the code used to compile and create the game and it would help if we had the sourcecode ... Some people here really need brain upgrades. No offense.

You just revived a three year old topic. Good job at the brain.

Could a admin explain?

I downloaded it before my computer was formatted.

well FQuist made an VERY FASt answer

But... WHY don't we have the source? Does nobody out of the dev team have it anymore? Does Epic just not want to give it to us?

Who knows? Maybe both?

Because if it's the latter, you could always say you're interested in developing a game with the engine. But someone who hasn't got moths flying out their wallets should do that. =P

They are probably ashamed of how badly coded jj2 is...

With IDA Pro, I decompiled JJ2 in .idb format, so use it! The link is right there!

...?!

Dont panic, people! I only opened the 1.25 ( I MEAAAAANNN.... 1.23 ^_^;; ) Jazz2.exe file with IDA Pro! It isn't the real JJ2 source code, but at least is a start. Oh, for editing it, you need the full IDA Pro!

Well, I remember someone coded a special version of Gens so it processed all the executed code in a ROM to a file. It *might* be possible to do with a PC executable, but it's unlikely.

EDIT: This isn't the real source, by the way, just a disassembly of the exe file. It might contain some useful info, though.

EDIT2: I've already found a lot of Dutch phrases, some sound references and some stuff about "SPAZ3D."

EDIT3: "Retail distribution of this code is strictly prohibited without written permission by Epic." Yes, maybe, but why did they write that vertically? :P And there's some cheats I've never seen before AFAIK, but I haven't cheated in ages. "jjrush," "jjgems," "jjending."

EDIT4:

.data:004CF8BC aTweedle        db 'TWEEDLE',0

Well, at least Tweedle has some remains.

.data:004D0D38 ; char aShield_plasma[]
.data:004D0D38 aShield_plasma  db 'Shield.Plasma',0    ; DATA XREF: sub_460F70+28o

Why is this here among the error messages?

.data:004D34B8 aServer_checkco db 'Server_CheckConnection: Client already active! DUH!',0

XD

.data:004D417C aThisProgramReq db 'This program requires a 256 color display mode.',0

o_O;;

CliffyB doesn't know where it is. I don't think we've heard from the rest lately.

jjrush, jjending and jjgems all exist and all well-known, but what you've done is really interesting, Thunder.

Don't you mean "Pako"? ;/

No, because Thunder posted all that stuff.
Pako disassembled JJ2.exe, but Thunder posted what he found.

And besides, IDA pro isn't exactly hard to find. I wasn't able to open Pako's file so I did my own disassembly. I think I might ask around SWS2B for tips on how to make a proper disassembly. Interestingly enough, TSF has a LOT more code in it's EXE, and JCS has some code which I originally thought was only for the game itself.

EDIT: The Mac version codes are also in the disassembly although they don't work AFAIK.

Double post, FOR GREAT JUSTICE.
I posted this over at SWS2B:

And got this response:

You, the user, have to improve the entire disassembly manually. But IDA can help quite a bit, with FLIRT, for example. IIRC, Jazz Jackrabbit was made with Turbo Pascal, IDA should be able to recognize and label the library functions of that automatically.
Of course you'll never get the original source code out of the disassembly, I hope that's clear.

This is pretty good news, but now we need someone who understands this stuff =P

Where's the 1.25 council when you need it...?

Fixed.

Uh? What happened? The 1.25 council got reducted to ONLY MONOLITH?!? OMG

JJ1 was made in Turbo Pascal, not JJ2.

Hmm... then what was JJ2 written in? I might be able to ask around, I know some people with programming experience.

C++

Whoopee! While I was searching about the weapon 0 mystery in Jazz2.idb, I found something about RingShot, Jazz3D, Spaz3D and Bird3D and SOCK.

RingShot: I'm not entirely sure what this is, where in the code did you find it?
[name]3D: This is probably referring to the 3D Bonus Stage sprites in Anims.j2a. Bird3D...hmm, me wants =P

..aaargh..

I'm not sure if it was ringshot, ringshoot, bellshot, bellshoot... I'll check later...

I think RingShot is somehow related to the Gem Rings.

Could be, but I've found with other things that the code around it will give you a hint. Well, until we get a C++ programmer here anyway =P

i think i will lurn c++ on school soon

They should teach you how to spell first.
