EDIT: Hello again! The guide has been updated as it turns out I made a huge mistake! Make sure to always edit your remote save file, *not* the local save file, as this is automatically overwritten by the remote save file!

Hey all! This is a brief guide on how to edit your save file in Shovel Knight: Pocket Dungeon. I won't go over everything that's possible, I'm just going to cover the necessary part for setting up a speedrunning save file.

First and foremost, if you just want to unlock everything - there is a cheat code for this. Go to the title screen and input the following sequence: [Up Up Down Down Up Down Up Down Left Right Left Right Esc Esc Esc]

With that out of the way, let's take a look at your save files. You have two identical save files appropriately named "save" in two different places.

1. Your Steam cloud save, found in C:\Program Files (x86)\Steam\userdata\{USER ID}\1184760\remote
2. Your local save, found in C:\Users\{USER}\AppData\Roaming\Yacht Club Games\Shovel Knight Pocket Dungeon\76561198157672095

When tinkering with your save file, you should only edit the remote save. It will automatically override the local save when edited, so there is no need to worry about the content of the local save.
The save file can be opened in Notepad, and it is very messy. You can use the Ctrl+F feature to find the fields you need.
The most important field is "blessing unlocked X". These are the relic unlock conditions, ranging from 0 to 36 for each relic (including DLC). Since the first 15 relics are unlocked by default, changing their values does nothing.
This is the list of fields you can change. Copy the "blessing unlocked" part into the Find menu of your save to locate them.
You'll see a value, either 0 or 1, next to the property. 0 = locked, 1 = unlocked. Change this value however you like.
