Harvest Moon - FoMT GBA Hack?
« on: March 04, 2019, 06:51:45 am »
I'm a newbie modder that currently trying to mod Harvest Moon FoMT.
I read some thread about HM-FoMT and some people leaving this series because it's too complicated to hacking this ROM since we can't find the pointer table for dialogues. I face the same problem. I think ASM knowledge is required to mod the story.

What I found just some adjustable parameter listed here.
-edible items (id, drink/eat, stm recov, ftg recov, pointer for name and description)
-non edible items (id, pointer for name and description)
-shippable items (id, sell value)
-horse race medal exchange (adjustable amount of medal)
-shops (buying price, buying item/tools but not all ex: I can't mod ore needed to upgrade, making jewelry, switch cow and chicken buying, and other non-direct item/tools buying)
-NPC displayed name and their birthday
-Recipes (id, stm recov, ftg recov, required utensils, ingredient sets)

anybody have same interest to mod Harvest Moon - Friends of Mineral Town?

While I'm not hacking games myself, I enjoy what people make ouf of them.
I was wondering why nobody started research/hacks of FoMT, but your reply gives away that the structure of the ROM must be much more complex than what I thought (not that I could fathom any of that magic anyway).

But yes, I'd enjoy seeing people mod FoMT.
Looking forward to what you (and anyone else, for that matter) discovers about how the game works.  :)

For my own project, I adjust the price to real price standard to make the game more challenging.
Base on my research, 1 G in HM FoMT almost same as 1 Japan's Yen.
So I made some adjustment like price for cow is 200,000 G beside chicken price is good at 1,500 G (original price).

I still try to "dig" the hexa to find out more interesting things.
I'll upload the spreadsheet and hexa mapping later, after I make it more understandable.
If anyone have another research in HM-FoMT, I gladly to help your own project too.

This spreadsheet is my documentation about what I found while reading the ROM's Hexa.
https://drive.google.com/file/d/1HZco38hT4fXyiU4TR5_8OD4m1zVAsSnV/view?usp=sharing

some interesting in recipes section are:
-we can put poisonous mushroom in miso, curry, and some recipes which give "bonus" SR:-60 FR:+20
-almost all edible things can tossed in curry and stew recipes
-Elli Leaves, which is legend for us that give SR 100 FR -50, can be improved by second recipe (Elli Leaves + colored grass) which I found that the maximum recovery is SR 190 FR -100 (I wrote the combination in the most right of recipe's child sheet).

Feel free to do the experiment by what I share, you can message me if you need to ask some question (of course about what I shared), and if you found something else that we can improve this series hack better.

For NPC Sprites, I haven't done address mapping of each character, so I'll share it later.

I also would like a hack of this game, once I tried to make modifications, but I could not. I wanted to add more characters, items, animals and decorations as an example these images:

Quite literally all I want is a GBA remake of Harvest Moon 64. Sadly I don't know how to make rom hacks. And i don't know where to get the tools for FoMT.

The problem is no knows how to edit this game's event. If you just want to customize character's appearance. It's still possible. But not their event. Change the dialogue is possible with limited action.
