Version r1.0.5
A Pokémon Platinum Overhaul Hack
Modified from Pokémon Renegade Platinum by Drayano, with permission
Note: b1.2.1 and b1.2.0 contain a game-breaking bug where Fantina's script in the Contest Hall won't play properly, and progression is impossible. Please update as soon as possible!
The game crashes when the first Barry battle begins if you did not use a Revision 1 rom to patch. This is a known issue, and not possible to fix, as this hack was based on Revision 1 of Platinum.
Also, since the game's code is different, I cannot guarantee that patches for Renegade Platinum will work correctly with Altered Platinum. If you use any additional patches, I may not be able to fix any issues you encounter.
Introduction
Pokémon Altered Platinum is a Platinum hack which makes radical changes to the way the game works, for the sake of fun and a fresh Sinnoh experience.
Meet 30 new Sinnohan forms(not rushed, just been working on this thing for WAY too long), each with a unique design, type, stats and more!
Play with old Pokémon that have been changed so extensively that it's like they're brand-new, and get used to an overall higher standard of power where almost everything should be usable.
The Ice type has undergone some extensive changes, with its Rock weakness removed and new resistances to Water, Ground, and Dragon.
Face an increased challenge, that isn't quite Kaizo levels, but it's definitely tougher than base Renegade Platinum. With the removal of effort values, you're limited to roughly the same level of power as the NPC trainers(who also can't use EVs), and you don't have to EV grind for hours!
Gym Leaders are no longer limited to types! Instead, their teams are centered around a particular gimmick, such as Roark's Stealth Rock team.
Play around with some new moves with (sorta)custom animations, such as the low-power physical Fairy move Roughhouse, or the 100% accurate, 90 power, no effects physical Flying move Meteor Dive! Some are even signature moves, such as Skarmory's Steel Feathers or (SPOILER)'s Cosmic Void.
Find newly recolored shiny Pokémon, like an autumn-colored Leafeon, or cherry blossom Torterra, with Renegade's 1/512 shiny rate included!
Some NPC dialogue that didn't give lore or story has been replaced(not all of it yet). This includes new jokes and references, but also some extra lore for the new Sinnohan Forms, to help them truly feel at home in this brand-new Sinnoh! Each new form even includes new Pokédex entries!
On top of all of this, there's even a familiar face as a new postgame boss trainer, whom is equivalent to Renegade Platinum's Steven Stone battle. Check the Screenshots spoiler for more info!
Note: This is my first ever romhack, so if it's a little rough in places, that's why. Still, I've been iterating for quite a while, and I think it's a lot of fun! I hope you enjoy!

Download (Documentation included!)
Contains all current and previous versions.
Note: This hack requires that your vanilla Platinum rom is Revision 1. It will not work correctly with the older version.
This hack is also based on an older version of Renegade Platinum without the Steven fight, though a different- but equivalent- fight has been added.
The custom sprites(packaged in a .zip separately from the releases) in this Google Drive are also free to use, but credit would be appreciated!

Changelog (Unmarked Spoilers!)
Tools Used
JackHack Tools: Like Drayano, I used a bunch of tools from his site, such as the DPP Attack Editor, DS Pokemon Editor, PokePicDS, and so on.
WPEDS: Used D-Trogh's Wild Pokemon Editor DS for most of my encounter edits.
PPRE: Mostly just used it for the trainer editor, everything else is kinda unstable...
HxD: A capable hex editor, which allowed me to do things like change sprite animations and offsets, and replace TMs
DSPRE Reloaded: Using this now for trainer, text and script editing in place of PPRE.
BTX Editor 2.0: Used it for replacing overworlds. Made the whole process far easier.
