Mechanics - inside Rebellion

vakundok · February 19, 2003

OK. I start this topic to publicate any knowledge and thought about how Rebellion works. This topic is only for those who have programing skills.

vakundok · February 20, 2003

The normal gamedata files (all *sd.dat except basicsd.dat.) have a common header. It is four DWORD long:

-always 1

-the number of things consisted

-the "lower" consisted family identifier

-the "higher" (not consisted) family identifier

The "higher" family identifier is usually is higher by steps of four except that of the facilities which are separated.

This does not apply to the *tb.dat files which have completely different structure.

Eg:

The troop family is 16, so the header of the Troopsd.dat is 1,10,16,20.

Next are the capital ships: 1,30,20,28 (Death Star is 24 all others are 20), the fighters: 1,8,28,32, and so on ...

However when I tried to add a new sector (data to the sectorsd.dat and name to textstrat.dll) to the game I failed so the number of consisted things (or maybe the file lenghts) must be stored elsewhere too.

SWARMER · February 21, 2003

the program is probablly either storing that file somewhere else or it has "identified" the amount of files there are. Eg Sectors - it only accounts for 10 lines of files... Mabye

Possible, that you're alone with your skills here Vakundok? We need more programmers for this problem!

Help Wanted

vakundok · February 24, 2003

No my skills are not up to the task. A cracker would needed not a simple programer.

deXtoRious · February 24, 2003

Wow, cracking!

What do you want to crack?

vakundok · February 24, 2003

Wow, cracking!
What do you want to crack?

Excuse me, but have you read the topic title? I would like to know how does Rebellion link things (the different data files and dlls) together and I would highly prefer the source code of Rebellion.

Hastings · February 25, 2003

I noticed there were patterns in the .dat files about 2 years ago. My text file which had certain hex locations are long gone, unless I have them backed up on CD somewhere. I have also tried to add systems and sectors without success.

The source code would be of great help. I mean, this game is going on 6 years and Lucasarts, being like they are, will probably never release the source, unless they can somehow make money off it.

Vakundok is not alone with his expertise, I have C++, C, VB and hex experience so I can look around the files in hex code. But converting hex to C++....meh, I'm sure it could be done but it might take a while.

SWARMER · February 25, 2003

good luck. My experience lies only withen VB(gr 11 Programming - i am only in Gr 11...)

the_mask · March 18, 2003

Thanks for posting this. Now we just have to know how the planetssd.dat works to make another planet the imperial capitol for the TC. Btw, I'll mail you the things I meantioned earlier as soon as possible

vakundok · March 18, 2003

Good, I am waiting for it. Well, I have a theoretical structure for the systemsd.dat, but I don't have the time to really check it:

Header: 1,200,144,152

Structure (11):

1 - number (starting from 100)

2 - unknown (maybe the active flag), allways 1

3 - unknown, allways 0 (since it canot be produced)

4 - unknown, allways 0 (since it canot be produced)

5 - family, usually 146

6 - identifier (actually two WORDs the second is 2 the first can be used directly to get the name from Textstrat.dll)

7 - sector number (starting from 20, since the number of the sectors also starts from 20)

8 - type (picture)

9 - unknown, usually 1

10 - position (actually two WORDs, x and y, not relative to the sector position)

11 - unknown, usually 0

The position is very interesting, it is not counted in pixels (maybe it have to be divided by two) and 0,0 does not mean the topleft corner of the screen. I think there is an area larger that we can see during the game and the coordinates are relative to the topleft corner of that area.

The header suggests that there are more families, not only 146, I will check the family of Coruscant and Yavin soon.

the_mask · March 18, 2003

Ask Hastings about these coords, too ! As far as I can remember, he posted something about changing the positions manually in the semi-old forum. It was something about a planet that seemed to have vanished, then he found it was 'below' another

Well, at least this universe was truly 3D.

vakundok · March 18, 2003

Well, I positioned a whole sector to 0,0 and it showed up over the interface outside the starfield. I will try to find what are the maximum relative positions within a sector to display a rightbottom planet properly (not only partially), but it will take a huge amount of time.

Hastings · April 2, 2003

Heh, that was interesting the_mask. I made one planet(i think ghorman) have some of the same attributes as Coruscant in hopes to make Ghorman belong to the Empire at the start of the game. What I found was...unexpected. I thought I had deleted the planet when in fact it was behind Coruscant. I noticed the text for Coruscant was messed up and barely made out Ghorman. So much for that.

I've spent hours & hours in those planet .dat files and was never figure out how to get one planet to belong to a certain side at the start of the game. I don't think it can even be done just with editing the .dat files since the .dat files contain static data.

Very interesting vakundok. I never went into much detail as you did with those .dat files. I believe in the systemsd.dat file, the 2nd position which you said is to be unknown is actually what determines whether the planet is populated or if the game randomly generates if it's populated or not. It is always 1 but I believe if you change it to 0 the planet will be populated. I'm not to sure since it's been ages since I've played around in those .dat files.

With those values you are putting up on the forum, it wouldn't be hard to make another editor for Rebellion. Sure it'd be the same as RebEd but it'd be new!

Btw - if anyone wants my SWR patch, talk to me, or perhaps the_mask(if he allows). you'll be able to run SWR without the CD which allows for some good editing. Good luck guys!

Tsunami · April 29, 2003

I had some problems with planets, too, and decided to completely run around the wall: I switched Coruscant and Yavin sectors (they are called differently, I know), switched pics, names and descriptions. -> The Alliance starts on Coruscant and the Empire on Wayland. Of course the new Coruscant is no longer a game critical planet and has the great range of starting energy and resources, but just for appearence's sake it was good.

The starting conditions have to be stored in the .dat files, but there are not many. I think there are random seeds for unknown, two different ones for known (according to priority, like low for Outer Rim and high for Core, changeable in RebEd), one for Coruscant and one for Rebel HQ. Yavin appears to be randomly chosen from the 'unknown' or 'known, low priority' chart.

Just from a non-coder point of view.

the_mask · April 29, 2003

Btw - if anyone wants my SWR patch, talk to me, or perhaps the_mask(if he allows). you'll be able to run SWR without the CD which allows for some good editing. Good luck guys!

I don't get, what you mean with if he allows, but I now remember something about your revised version of the patch, I'll mail ya about it.

This patch also allows you to use new movies and music for Rebellion, without having to somehow make a new CD image with those new files.

vakundok · April 29, 2003

Tsunami:

Yes, there are the Cmuncrtb, Cmunyvtb, Cmunhqtb dat files which store the defenses of the starting locations and Faclcrtb and Faclhqtb dat files which store the facilities of those. In my opinion, Coruscant and Yavin must have been special family number, but I have not checked it yet.

Presently I try to understand the mission description file. (The first result of this is the cheat that (most likely) allows the assasination missions for rebell characters.) Besides I will soon try whether it is possible to turn a ship (shiptype) to a planet destroying super weapon or not.

Tsunami · May 9, 2003

I checked out hexing shipstats.

The game will tolerate a zero for sublight speed and actually show it as zero, but effectively speaking, the ship still has a sublight of one.

It will also accept a zero for hyperdrive but will show it as 180:0 and 180 is the real hyperdrive rating. I think 180 is the lowest a hyperdrive rating can fall to when damaged.

I tried negative values (which are simply shown and put to work like they were positives) and HUGE numbers to see if there was a cap and a turn into negative or somesuch; no banana.

Seems to be that the 180:0 thingie is hard-coded elsewhere, maybe someone can find out where.

The weird thing is that a ship with a zero for either value shows no indicator for that component in tactical (they appear not to have a sublight drive etc.) so that this component cannot be disabled via tractor beam or ion weapons. There could be some way to exploit this.

Trejiuvanat · May 10, 2003

So ther eis no way to get ship with no hyperdrive at all?

vakundok · June 19, 2003

I do not know, whether Tsunami sett both the hyperdrive and the backup hyperdrive to 0 or not.

(Side note: DWORD means 32 bit unsigned integer type and WORD means 16 bit unsigned integer type.)

Cain · March 6, 2004

Well I'm not a programmer I only have an analytic mind ...so I have send today some ideas to Mask about cracking the source code...I hope they are good enough to pot you guy's on the right track

Also Mask has a good C3PO so you could understand it well

I hope that with this theory you guy's could see all there is to see in that hated source code .
