Hello everyone! Here is the presentation of my rom hack: Pokemon Mystery Dungeon: Explorers of Hell and Pokemon Mystery Dungeon: Explorers of Heaven. I've always loved Pokemon Mystery Dungeon, but I was always frustrated by the lack of difficulty, and the fact that the game was finishable without using all the QoL offered by the game, like IQ, linked moves and other mechanics. After discovering SkyTemple, I tried to create my own rom hack, and finally get the game I always wanted to play.

With Pokemon Mystery Dungeon: Explorers of Hell, you can expect : 

- A very high difficulty. 
- New starters and new Pokemon from generations 5 to 8.
- New dungeons, boss battles and items. 
- New dialogues (lots of memes and humor).
- The fairy type added.
- And other features.

In this thread, I will present you some new features, you will also have some screenshots of the game, and you will have some data related to the game, like the list of legendary Pokémon that can be found with the mystery part/secret slab or the list of new attacks. First of all, I want to thank the whole SkyTemple team, this would not have been possible without their engine and hard work. I also want to thank the spriters without whom the new Pokémon could not have appeared in my game. Finally, I would like to thank Mond who generally helped me a lot in the creation of my rom hack. He also created his rom hack: Pokemon Mystery Dungeon : Explorers of Alpha, I invite you all to go and see his project. Remember to talk to the Porygon2 in the game crossroad for a detailed list of spécial thanks.

What is the difference between Explorers of Hell and Explorers of Heaven ?


Explorers of Hell has modified dialogues, with a lot of dark humor, and Explorers of Heaven keeps the same dialogues as the base game. If you are not comfortable with dark humor, You should play Explorers of Heaven.


Random features :


- You will have access to "farms" dungeons with the spinda coffee. You will be able to farm the IQ, money, and get some importants items like the Friend Bow.

- Some pokemon abilities have been changed or added. I won't spoil everything, but for example, Cranidos gets Rock Head, Ninetales gets Drought, Ponyta and Rapidash get Quick Feet instead of Run Away etc...

- The puzzles in the Aegis Cave will be much easier to do, the stones will take less time to find, for example the Ice Aegis Cave will only have Unown I, C and E.

- 5 dungeons "The Hell", all with different characteristics (For example, The Hell North will be the succession of all the bosses with "rest room" between 3 bosses) but an extreme difficulty.

- Some Pokémon will have their shiny forms in the game.  The list of Pokemon and their location is further down in the thread.

- When a legendary Pokémon has 999 IQ, he can change his form to shiny. Giratina will be able to freely change between its two forms when he has 360 IQ. Dialga will be able to change his form and become Primal Dialga with 360 IQ as well.

- The effect of some attacks has been changed. For example, Surf hits the whole room, Knock Off deals damage, Howl affects all allies, and many other changes and adjustments. Speed increasing moves have received a big PP nerf. 

- The speed increase and decrease time has been reduced.

- After graduating from the guild, you will have access to the futures dungeons

- In the basic game, pokemons appear every 36 turns. Here, they will appear every 11 turns.

- All Pokémon in the game will be recruitable, including Purple Kecleon and Arceus.

- The Oran Berry now gives 250 HP.

- Intimidator IQ Skill now has a 16% chance to activate instead of 32%.

- Pokémon now have their egg moves as well as their new attacks in their level up moves.

- The Marowak Dojo will feature 4 very difficult floors and an extremely difficult boss at the end. I recommend you to try it only after finishing the post-game.

- There are many more features, but I let you discover them by playing the game.

New gameplay mechanics :


- After the quiz, you can choose if the starter suits you or not, like in the recent PMD games (thanks to irdkwia).

- You don't have a boring tutorial when you start the first dungeon (thanks to End45).

- Teammates can now activate traps (thanks to Cipnit).

All Pokémon gain experience points, even those that have not been in the dungeon, as in recent PMD games (thanks to irdkwia)

- By pressing start, you can change between automatic and manual mode. The manual mode allows you to completely control your team during their turn (thanks to Cipnit).

- There is the Move Shortcuts system like in the recent PMD games. By pressing L + A/B/X/Y, you can choose a move to use (thanks to End45 and irdkwia).

Thanks to Fke for designing the text box and the teams stats. Thanks also to all those I didn't mention.

It's thanks to your messages and your support that I had the motivation to work for several months on this game, so a huge thank you to you, and I hope you will like the result.

You will need to patch a Pokemon Mystery Dungeon: Sky Explorer US rom. Avoid using savestates to apply future patches. In the file, you will have a tutorial to patch your rom. If you have any question about the patch, the game or anything else, feel free to send me a message on discord : babou#0001, to come in my server (https://discord.gg/6QbPHYZDtg) or to send me a message on twitter : @babouzzz
