This script assumes you have found the Stamina address and performed a "Find out what writes to this address." It creates a code injection that keeps the value from decreasing.
[ENABLE]
// Code from here until 'DISABLE' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
newmem: // This is where the code goes
// Instead of decreasing, we do nothing or write a max value
// Example: mov [ebx+00000100], 64 (Sets stamina to 100)
jmp exit
originalcode:
// This would be the original code you found (e.g., sub [ebx+100], eax)
sub [ebx+00000100],eax
exit:
jmp returnhere
// "Emulator.exe"+OFFSET is a placeholder for the real address

Before you start freezing values and editing hex strings, you need the right setup.
If you want to hack specific things like Infinite Stamina or Stop Time, you need to find the code that writes to those addresses and use an AOB (Array of Bytes) injection.
Note: These scripts may require a specific emulator version to work perfectly, as memory locations shift. cheat engine harvest moon back to nature
Because the PS1 memory addresses shift, you cannot simply type your gold amount into Cheat Engine and hit "First Scan."
The Correct Method:
If you want to change a branch in your rucksack into a Goddess Jewel, you can use Cheat Engine to change the Item ID. This script assumes you have found the Stamina
Popular Item IDs (Harvest Moon: Back to Nature):
(Note: IDs may vary slightly depending on the version of the ROM/ISO you are playing. Always make a save state before editing memory.)
The Golden Rule: Only cheat for convenience, not substitution. Use it to remove grinding (watering crops, chopping wood), but let the story unfold naturally on its own. Before you start freezing values and editing hex
One of the most frustrating parts of HM:BtN is the "108 item" delivery to the Harvest Goddess. To marry the Goddess, you must ship one of every single item in the game. Doing this legitimately takes years in-game.
With Cheat Engine:
Gold is the easiest value to find. Let’s do a practice run:
Congratulations. You have just performed your first memory hack. Now, let’s go deeper.
