Hello all!
Does anyone have an idea how to extract, then reinsert, the .mpak files (Dialogues) and the .pak files (Images and fonts) of the game "Mega Man Battle Network Legacy Collection" (From Capcom) please?
Here attached, some example files

The header of the text files (message_X.mpak) is identical in the first 0x36 bytes, which seem to be addresses; thereafter, a sequence of bytes is repeated, with the second byte increasing by 1 each time

The first four bytes of the image files (.pak) contain the address where the image starts; but without a magic word, it is impossible to determine what the format and encoding of the image is
I don't know what the following bytes correspond to

I also send a chip_base_d_eng.pak file, the biggest of the game (16Mb), whose header is ultra complete, it is likely that there are several images in the file, and that these addresses all point to an image

Thanks in advance

The game uses custom table.

I will write detailed instructions on how to handle this file type soon tomorrow. This is the result after processing the files.

I was just working on a software to extract the texts...

Thanks you very much, it's work perfectly!
I would have to still see the images, because some of the text is not plain text; and the font doesn't seem to handle special characters like "e" or "E"...
Anyway, many thanks to you!

For the font you can use this to extract .pak and edit font

pak_and_fnt.rar

Thanks very much! Again, you're real lifesaver!
It seems I had some problems, of course... xD

The first one concerns the extraction of the images, this works well up to the "network_loser" file (Or the following one, passcode_spr)


The second, when extracting the eng font


Did I do something wrong? :/

For the font.pak files you need create new folder like this "\exe1\data\ui" then copy your font file in folder ui.
Then you need create folder name "exe1_output" , and follow like this command:
"python3 extract_pak.py .\exe1\data\ui .\exe1_output"
The fnt font only using for version 4,5,6.

Okay, so from what I understand, it's not possible to change the font of version 1, 2, 3, right?
