ROM Hack Harvest Moon - A new beginning => Scripts etc in Plain Text

ChrisX930 · Feb 26, 2015

Hey Guys,

right now, I wanted to get a 3d-Banner (cgfx?) to test it for a Homebrew and I decided to decrypt "Harvest Moon - A new beginning" for it to get a example.
But now, I found many MAAAANY ".nut"-files in the decrypted romfs.
the nut-files are all scripts of this game in Plain Text, which means, I'm able to edit ANYTHING code-related of the game (which is fantastic!)

Here's a example:

I Just wanted to share this with you

yes, that should be possible.
There are more interesting things in the files, like this:

Code:

PlayerMoney <- {
    Init = 500,
}

or

Code:

//    アバターのデフォルト設定(男)
PlayerAvatarDefaultBoy <- {
    Body = "M_UNIFORM_1",
    Head = "PLAYER_HEAD_0",
    Hair = "M_HAIR_FARM_STYLE",
    EyeColor = 0,
    HairColor = 0,
    EyeShape = 0,
    Skin = 0,
}

or Spawning Locations of Items

Code:

function InitFieldItemAdvanced()
{
    InitFieldItemCommon()
 
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_1", 6, 95.80, -185, 5, 1 );//森マップ
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_1", 80, 95.80, -146, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_1", 145, 56.79, 89, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_MOON_DROP", 90, 56.79, 40, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_MOON_DROP", 31, 56.79, 31, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_1", -40, 56.79, 23, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_1", -45, 56.79, 40, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_2", -27, 56.79, -80, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_3", 200, 0.79, 167, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_3", 211, 56.79, -17, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_3", 175, 59.71, 25, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_2", -300, 30.79, -4, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_2", -103, 12.51, 28, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_1", -145, 12.51, 58, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_MOON_DROP", -142, 12.51, 102, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_3", -98, 0.79, 200, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_MOON_DROP", -212, 0.80, 254, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_3", 64, 0.79, 214, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_BRANCH_2", 36, 0.79, 224, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_STONE_3", 225, 0.79, 200, 5, 1 );
    FieldItemManager.Get().Place(FieldData.GetID("MAP_FOREST"), "ITEM_MOON_DROP", -24.18, 56.79, 32.59, 5, 1 );

also I found the Shop-Items

Code:

function InitShopCommon() {
 
    //雑貨屋
/*    ShopData.AddShopItem("SHOP_ITEM_ONION_SEED");
    ShopData.AddShopItem("SHOP_ITEM_TOMATE_SEED");
    ShopData.AddShopItem("SHOP_ITEM_SPINACH_SEED");
    ShopData.AddShopItem("SHOP_ITEM_CARROT_SEED");
    ShopData.AddShopItem("SHOP_ITEM_WHITE_RADISH_SEED");
    ShopData.AddShopItem("SHOP_ITEM_BROCCOLI_SEED");
    ShopData.AddShopItem("SHOP_ITEM_SUN_FLOWER_SEED");
    ShopData.AddShopItem("SHOP_ITEM_RED_ROSE_SEED");
    ShopData.AddShopItem("SHOP_ITEM_PINK_SEED");
    ShopData.AddShopItem("SHOP_ITEM_SNOWDROP_SEED");
*/    ShopData.AddShopItem("SHOP_ITEM_FOOD_GRAPE_WINE");
    ShopData.AddShopItem("SHOP_ITEM_RISE");
    ShopData.AddShopItem("SHOP_ITEM_RISE_FLOUR");
    ShopData.AddShopItem("SHOP_ITEM_FLOUR");
    ShopData.AddShopItem("SHOP_ITEM_BREAD_FLOUR");
    ShopData.AddShopItem("SHOP_ITEM_OIL");
    ShopData.AddShopItem("SHOP_ITEM_SPICE");
    ShopData.AddShopItem("SHOP_ITEM_CURRY_FLOUR");
    ShopData.AddShopItem("SHOP_ITEM_COFFEE_PACK");
    ShopData.AddShopItem("SHOP_ITEM_COCOA_PACK");
    ShopData.AddShopItem("SHOP_ITEM_TORYUFU");

Back when this game released I ran into a lot of this: (phone quality incoming)

It looked like this game used basic HTML, now I see I wasn't too far off from that assumption...

I had this too ^^
Yea, the Strings seems to be saved in the xbb-file "Msg.xbb".
the xbb seems to be a compressed, not strong encrypted file format, but I'm not able to decompress it (because idk how to do it).
Is there someone who can handle this for me?

nosklo · Feb 26, 2015

Hmm very interesting. Maybe we could write a tool to convert rpgmaker-style games into animal crossing mods?

Harvest Moon =/= Animal Crossing, lol xD
But yea, I thing I should be able to create something own with it when i know how to decompress the xbb files

Additional Info:
The Code seems to be in Squirrel Language

Gryphon93 · Feb 26, 2015

Hm... Interesting. It seems like the scripts for the game is written in Squirrel (http://www.squirrel-lang.org). That's my guess based on the syntax and the file extension. I love it when developers do things like this. It makes it really fun to go through the contents of the game. Nice work finding it, ChrisX930!

I've kind of reverse engineered the XBB file format back when HM: IoH came out. I made a small tool in Ruby which extracted files from the XBB file, but it can't put it back together (even though it's a pretty straight forward job). The format is simple, but I haven't figured out what type of compression (I assume the data is compressed) is used for the files in the XBB file. I don't have much time to work on a proper tool right now, even though I promised another GBATemp member I would create one last summer... Anyways, if you have some programming skills you will easily be able to put a simple un-/packer together. The format is quite simple, as I mentioned earlier.

[Edit: I assume the format is the same in HM: AnB as it was in HM: IoH and HM: SI, but I don't know]
[Edit 2: I didn't see that you already had mentioned Squirrel in your previous post. Sorry about that.]

Thank you for the answer

I'm already trying to write some un-/packer and I hope I get it to work

If you need the "documentation" I will gladly share it with you. I don't remember if it is totally up-to-date though.

xbb file is not compressed, is plain archive format without any compression on 3ds version (not like on ds, is compressed on second generation of engine). is same as xbb format on Island of Hapiness format , but is have extra byte on it. most of text is stored on Msg.xbb, but name of item/character/etc is stored on individual file on data setting iirc, and is stored on special format pp (magic header : PAPA)

you can check it on https://gist.github.com/andibadra/2632d06a7066224ae08d#file-9_format_xbb_3ds-md .

Finally I got it to work to rebuild the romfs.bin AND the rom with changes on the scripts!
Here's a example that shows new options in the male avatar creation! (added female options to it)

Can you give the Girl or Guy clothes from other characters? Like use the body id of the harvest goddess or something.

Sure, it should possible!
I only need to find the right values for it (ID of Harvest Goddess Body)
