Guys, I need help
When I repack Models.H2O from the extracted files and play with the repacked file, I get a crash just after the first loading screen.
I did NOT change anything, just extracted and packed, to test. I tried with both cmd and GUI, nothing to do. I noticed the file changes its size a little (original = 97.477 KB, Repacked = 97.816 KB).

By any chance, do I need some kind of patch to Battle Realms in order to get it to work?

UPDATE:

Apparently i'm not the only one with this problem, and I tried to take action.
Opening the original file (this time interface_text.h2o) with the hex editor, all what i could see was a bunch of incomprensible bytes.
Opening the repacked file... surprise... the text was still perfectly readable, just like in the extracted files.
So I looked into the source code.

This is from cmd_extract.c, line 25 and following:

			if (node->file->entrytype == ENTRYTYPE_COMPRESSED) {
				printf("decompressing file: %s\n", node->name);
				dumpchunk(src, dst, node->file->checksum);
			} else 	if (node->file->entrytype == ENTRYTYPE_RAW) {
				printf("extracting file: %s\n", node->name);
				dump(src, dst, node->file->size_raw, node->file->checksum);
			}

This is from cmd_build.c, line 36:

entry->entrytype = ENTRYTYPE_RAW;

Not compressed. Just like the file I checked with hex editor.
Maybe I've figured it out, but i'm a noob () and i can't c0mpile (usually that word gets you an error in forums) it.
I'd try to replace that line with

entry->entrytype = ENTRYTYPE_COMPRESSED;

... and have a test. Who knows.

I will like to add something here. The repacks tools are not always perfect because sometimes they use differents algorithms of compression to achieve the same result, the expected file may vary, while sometimes it will work fine in others it may crash the application (the game) because of misplaced bytes, loss of information in the compression data process and random errors.

You can check this just by extracting the file and then repacking without changing anything, most of the time the CRC and checksum of the file will be different of the original one unless is a well documented type of archive. In BR we don't have such luck, but H2Otool is a good and useful tool nonetheless.

It extracts perfectly.
But the problem is packing.
I don't think the output is compressed at all; i was able to read each string of the text interface files I included.
While in the original packed .h2o i can't read any string, just some "ÿÿÿà 1•â" for example.
Oh well, i'll have a look at the algorythm and try to make my own VB6 program to extract/pack; i'd better not get my hopes up anyway.

You don't. But someone has made a mod for that. Try searching.

Ok guys great tool thank you very much.
But I have a problem. I played around with the rice texture, repacked everything and started the game. Everything worked fine and the rice texture was the one I created, BUT when I play the game I see black tiles on the ground:



So I unpacked the original textures again and repacked them immidiately without changing anything to test if the packer is the problem and it seems like it is the problem because the same shit happened again. I tested this with both packers and several times. Any suggestions are appreciated. Thanks!

EDIT: These tiles are under buildings aswell but in a lighter color. I painted the shadow of people green to see if it has an effect but it changed nothing. Black tiles again :-(

Hi, im trying to edit the textures on the models.h2o file, but i cant rebuild this file, because when i launch the game , it crash, and says: "GATHERPOINT_DRAGON.lmd"

I know that im not the only with this problem, but i cant figure out, how to solve it, or i dont know if this file cant be repacked again, because i follow the tutorial of extract-build (Zymeth tutorial) with textures.h2o and works, but whit this file not...

Hey any body found solution this problem..tht extract n repack of models.h20 files?
H20 GUI/cms both gives error..anyluck with anybody?
