tool PMD2 - SkyTemple ROM Editor (Maps, Scripts, Debugger, ...)

Hi!

A few months ago I wondered if there are any tools to make custom PMD2 ROM Hacks. I found out that much work on the games had been done, but there wasn't really any user friendly GUI editor to make custom ROM hacks. So I decided, I'd give it a shot and try to make my own.

This tool can edit both the ROMs of Pokémon Mystery Dungeon Explorers of Sky EU / NA.

Now, before I begin, I want to stress that NONE of this would have been even remotely possible without people like @psy_commando, @Nerketur, @evandixon, @MegaMinerd or any of the other PMD ROM hackers. I'm not somebody who's good at reverse engineering ROMs or actually finding out how stuff works. They did all the hard work (especially Psy!) and they deserve all the credit for it! All I did was filling some gaps and building this editor, that I'll now present to you...:

Features

Map Background Editor

Let's you view and edit the backgrounds of the map. Supports importing map backgrounds from image files. The collision of the map can also be changed.

Scene Editor

Let's you edit the position of Pokémon and Objects on the overworld maps and change how cutscenes are built.

Script Editor / Debugger

Let's you edit the script files of the game and debug them in realtime.

> Script Editing

You can edit all scripts in the game with features like auto-completion and calltips.

> Debugging

You can set breakpoints and let the game halt at different parts of the code.

> Debug Overlay

A debug overlay shows you where objects, triggers and Pokémon are rendered and what their hitboxes are

> Game State

View the current state of the Ground Engine, the game's script engine: What scripts and scenes are currently loaded and which actors and objects are placed on the map?

> Variables

View and modify the current game variables in real time.

> ExplorerScript

ExplorerScript is a new high level language that the scripts in SkyTemple are written in. It is compiled to the binary code (SSB) that the game uses.

Dungeon Editor

Edit and create your own dungeons and customize the spawns for each floor.

Dungeon Tileset Editor

Edit the graphics of dungeon tilesets.

Fixed Room / Boss Fight Editor

Edit treasure rooms and boss fights, create entirely new bosses and assign them to dungeons however you like.

Ground Lists

Change various lists in the game, such as the starters, the recruitment list, a list of placable NPCs (actors) or the world map.

Pokémon Data

Edit the data of Pokémon, including stats, move learnsets and portraits.

More Features

• Apply ASM patches to add new functionality to the game
• Edit misc. graphics, such as the fonts or the message borders
• Edit all text in the game

I see that you are planning to add support for dungeon editing so I would like to help by posting everything I know about dungeon data in EoS, which I have compiled in this document: https://docs.google.com/document/d/1UfiFz4xAPtGd-1X2JNE0Jy2z-BLkze1PE4Fo9u-QeYo
I hope this helps with the development and makes everything easier. I'll join the Discord too, so feel free to ask me anything if you want.

Huge fan of this so far! Any idea when you'll be able to integrate the level up data?

Currently I'm working on dungeon editing (tilesets, floor data, etc.), after that I want to add the level up data.

A new version was released! It contains dungeon editing, tileset editing, starter editing and so much more!

See the updated main post for more details and a trailer!

This is incredibly cool!Very excited to see what kind of romhacks people come up with.

This is really amazing. I waited 10 years for mystery dungeon rom hacks. I was only wondering though. When I try to change my hero into a legendary / genderless pokemon, the screen frames become pink (this happens when you access the dungeons).

Now I know that this shouldn't really be much of a problem, but is there a way that the screen frames remains being blue when your hero is genderless?

What you can definetly do is change the palette for the female border to be the same as the male. Otherwise I'd probably require some code changes to make that work.

Changing the pallete for the female border to the male one would be a good option indeed. Still, I was just curious if it could be implemented with a code fix since I would have to do that for each rom hack I create! ^^

I can open it, my Computer says it is a virus.

Hi, 

1. that's not a virus message, it's just a normal message for most downloaded software. Click "Weitere Informationen" and it will let you run it. 

2. Until a few days ago Windows Defender acutally flagged SkyTemple as a virus. That has been cleared with Microsoft and it's no longer the case if you download the newest update of Windows Defender. 

 

There is no virus in SkyTemple.
