Dev's Limit Breaking 101 Techniques

Thanks to the wonderful tutorial on this, I was already able to change quite some nice stuff in the mod. But now, when attempting to remove the cruise speed display limit of 300, I came across something strange.

Looking at the relevant part from the Limit Breaking 101 offsets file:

freelancer.exe 0D5936 0F85->90E9 = remove cruise speed display limit of 300 ~Unknown

Now, if I have a look at offset 0D5936, I see this:

(Decoding Hexadecimal)

byte = f
signed byte = f
word = 850f
signed word = fff,850f
double word = ff75,850f
signed double word = ff75,850f
quad = d8dd,ffff,ff75,850f
float = -3.26351738686e+038
double = -1.21042962905e+120
word motorola = f85
double word motorola = f85,75ff
quad motorola = f85,75ff,ffff,ddd8

Note that there is no ‘0F85’ in there to be found. There are a lot of similar values, but nothing identical. Changing any one of these ‘similar’ values causes the game to ctd as soon as I charge cruise engines, so obviously something’s wrong.

All other edits I did went fine and without any hitch.

I am doing exactly what the tutorial says, and tried it several times. Why can I not see ‘0F85’, like the tutorial and the offsets list describes? I’m obviously overlooking something here… Any help?

(Decoding Hexadecimal)…

Note that there is no ‘0F85’ in there to be found.

It appears that you are looking at the “Simple Data Types” converter built into Hexplorer, Maverick. In this case, you do not want to decode the hex values – you want to modify the hex values directly.

Go to the address and just look at the bytes there. If you see “0F85”, then you are in the right place. If not, then something is wrong – either in your technique, or in your version of Freelancer.exe.

Note that there are several common Freelancer.exe’s floating around. There is the original, from the Freelancer CD. There is also a “no-CD” version that many players use for convenience (with our purchased Freelancer CDs safely stored somewhere). Also, many mods modify Freelancer.exe. So it is important that your version matches whatever instructions you follow.

If you modify the wrong byte, then the results will be unpredictable, as you have already discovered. And, by “unpredictable”, I mean that Freelancer will probably crash.

Does that help?

Yup, that did it. Thanks a lot for the info m8.
In the example used in the tutorial it doesn’t mention to just look at the hex, but tells you to use the Simple Data types modifier. So I was automatically assuming that this was the way to do it with any offset. Never occurred to me thought to just look at the code.

Goes to show, most problems that seem complicated are quite simple to solve most of the times. (if you know where to look that is lol)

Cheers m8.

And isnt actually 0F85 what you have decrypted as word 850f - its sometimes the hexeditor that shift the display wise, highbyte and lowbyte thingy….

Yeah I noticed the resemblance.

By the way:

Correction there: the tutorial does mention this. I just simply overlooked it.

Hi there, is there a way to have an higher number of player in one group ?

In exemple have 15 player in the same group ? Is there any offset to change ?

i make a pray to the God Of the Offsets…

Use FLHook
Simply modify the value in FLHook.ini

If you want to do it yourself:

#define ADDR_SRV_MAXGROUPSIZE 0x3A068 // 06D1A068
#define ADDR_SRV_MAXGROUPSIZE2 0x3A46E // 06D1A46E
(server.dll)

flhook.ini ? i dont have found this parameters, i use the 1.6.7 test 19

so
#define ADDR_SRV_MAXGROUPSIZE 0x3A068 // 06D1A068
#define ADDR_SRV_MAXGROUPSIZE2 0x3A46E // 06D1A46E
(server.dll)

this offset are for 15 players ?

It’s

MaxGroupSize=8

in FLHook.ini

8 Should be the default value afair.

ok thanks, i will look better in this files, las night i was tired, i think i havn’t look properly

–>
BA0100000090 freelancer.exe 1B264C cannon keep FL display running when the window doesn’t have focus

I believe this is the cause of issues when alt-tab’ing from fullscreen;

WARNING: RenderMgr - failed to create_buffers(1024,768) 32,-1

Basically it flashes to black screen and then stays there, clicking anywhere brings the window back into focus (I presume) without any visuals, just sound.

Sorry if this has already been covered, it’s quite difficult to troubleshoot through this thread xD

Any way to fix this?

Yay for Fox being back! Woot!

Nice work, Fox.

I’m going to try to update the wiki page later.

Surprised this one hasn’t already been posted: Does anyone know what changes are needed for the no-CD patch?

Huh, you may compare two binary files and get offset, but is it l3g@l?

FriendlyFire already posted the no-CD patched freelancer.exe in the downloads section: http://the-starport.net/freelancer/download/singlefile.php?cid=1&lid=2649

So I would assume so, yes.

No-CD patches are a gray area, but considering many bargain bin (yet still official) versions of FL include one, I don’t think they’d bother anymore

Doubtful. As far as I know, the original EXE is encrypted to a certain extent. The No-CD EXE has patches on top of a full decryption of said EXE.
