Pokemon Romhack Idea

3 Upvotes

Hi everyone! I’m not a dev, but I wanted to share an idea I just came up with because I thought it was pretty cool. I know nothing about making ROM hacks, so I figured I’d post it here in case anyone might be interested in giving it a shot.

The idea: You play as a Berry cultivator who owns a berry field. You grow berries and sell them for a profit. Every day, wild Pokémon are attracted to your berries and come to your field to try to steal them. You can either fight them off or catch them using your own Pokémon.

Occasionally, trainers will visit your field and challenge you to a battle. If they win, they get to take some of your berries for free.

The main theme would be a cozy, Harvest Moon-style ROM hack with some Pokémon battles sprinkled in here and there.

### Important notes

- Read the wiki guidelines before starting (especially about HMA, overworlds, and trainers).

- This is still actively developed — expect occasional bugs.

- Compile with the usual `python scripts/make.py` (or the included `.bat` helpers).

# We are developing our own tools for editing overworlds (complete), trainers (complete), DPE and pokemon related (Complete), Item editor (Complete)

HMA should only be used to edit maps and scripts.
