    ROM Hack Learning rom hacking on Metal Saga

    I've almost figured it out. Heres what i found : The first 2 bytes are the number of files in the pack (offset: 0x00000000) The 4 next are the offset of the pointer table for the files content (offset: 0x00000002) The 2 next are the offset of another table (offset: 0x00000006) After that and...

    Thanks Normmatt ! But do you know which "pack_data.pak" is red in this log ? Because i don't find any at 0x027E356C... And how do you get this log ? With the debug version of NO$GBA ? I definitely still have a lot to learn :)

    I've found the filenames, they are just at the beginning of the pak file, but no luck on finding the pointers for the moment... But I think the first byte indicate the number of files in the pack. And the graphics seems to be stored in .tex files, which i don't know anything about.

    Yep, i've succesfully changed some text with roman characters, that's not my probleme right now. No, the big issue here, is that i have to find a way to unpack the "pack_data.pak".

    ROM Hack Learning rom hacking on Metal Saga

    Hello ! Today, i tried to do a little work on another game : Metal Max 3. But I've already met a problem: the only files in the file system of the rom are named "pack_data.pak". Thoses seem to be collections of files with probably some compression. In crystalTile2, i can't find any japanese...

    There is about 640 bytes, and they are just between 2 blocks which contains text (in shiftJIS), so i'm pretty confident about using it :)

    I've found in the arm binary a huge block of '00' bytes, but i don't know if this is some free space or something that the game uses somehow :unsure:

    ROM Hack Learning rom hacking on Metal Saga

    Thanks for the answers ! As you say, the texts that i've found in arm9.bin are mostly menus and place names, every item names and dialogues are in specific files that i've manage to edit properly. So i think i will go with a mix of your solution 2 and 3. The game does use 16bit shiftJS, and...

    ROM Hack Learning rom hacking on Metal Saga

    Hi guys, here i am again. Lately, i've been trying to inject text in the file "arm9.bin". In order to do so, i've added some text at the end of the file, and i've tried to update a pointer with the adress of my new text (at the end, so), but it didn't work. That's odd, because i've succesfully...
