Diamond IronMON v1.0
Please note: this patch requires the (USA) (Rev 5) Version of Diamond to work correctly.
If you find anything wrong with my patches, or have any suggestions for improvements, please let me know through my DMs on Discord. You can find me in the IronMON Discord server (user ID: sentor_g).
It should look identical to this in the ROM patcher website

Why is my game crashing?
Pokémon Diamond & Pearl were released in April 2007 and Platinum was released in September 2008. In between that time frame, significant improvements were made to the engine which made Platinum, from a ROM hackers perspective, easier to work with and manipulate/edit. This also means that alternate forms of Pokémon, such as Deoxys, Rotom and Wormadam, will break the game.
I have formulated a 4.6.1 randomiser string to be used for Diamond Kaizo IronMON runs: 322WRIEEjKDAYYBiQGRAAKeBhsECQEAFAACCQAuEgAAAAAADBCI5ATkAYYICTIGBQIyAA0YE1Bva2Vtb24gRGlhbW9uZCAoVSmWHpX5d9pgcA==
Please adjust this to meet your ruleset requirements.
Please ensure the "No Irregular Alt Formes" box is checked.
Patch Modification List:
| Update | Details |
|---|---|
| Rowan Skip | Rowan introduction skip and faster character selection. |
| Options QoL | Set mode on by default. Many thanks to BlueHoney for help with the Hex edits. |
| Dialogue Skip | Massive dialogue overhaul from the moment you start to the Hall of Fame. Less yapping, faster battling. |
| Hands-free Briefcase | No buttons required through Lake Verity dialogue. Many areas have incredibly fragile code (in terms of randomiser compatibility). Game interactions have been shortened as much as possible while maintaining the ability to successfully randomise the ROM. |
| Nat. Dex | Acquire the National Dex when Rowan gives you the Pokédex inside Sandgem Lab. |
| Faster Healing | Faster healing at Pokémon Centers. |
| Name Raters | Name rater NPC Psyducks in all Pokémon Centers. |
| Friendship NPC (Sandgem) | Added a friendship-increasing NPC (with no limitations). |
| Tutorial Skip | Removed the catching tutorial on Route 202. |
| Expanded Pokétch | Loaded the Pokétch with the Clock, Memo Pad, Pedometer, Pokémon List, Pokémon History & Color Changer apps when you first pick it up. |
| Faster Fishing | Fishing with the Old Rod has a 100% encounter rate. |
| Moved NPCs | Minor specific NPC repositioning to minimise movement for the player. |
| Faster HMs | All HM moves no longer require a Yes/No input from the player to use in the overworld. |
| Honey Pivots | Honey trees now no longer require a 6-hour in-game wait to encounter and are instead instantaneous. |
| All-day Trainers | Removed limitations on trainers who battle at specific times of the day. The Seven Stars Restaurant is now open 24-hours. |
| No Sinking | Removed sinking tiles in the marshy areas and deep snow where applicable. |
| Iron Island * Trainer | Spinning trainer made static in Iron Island. This is to guarantee avoiding the in-dungeon battle before being allowed to do so (no battles before mandatory continuous NPC healing). |
I have created two versions of the patch.
The .xDelta file with FLX at the end will have the frame limiter switched off (faster).
I highly recommend using the FLX version.
