Tools -> Randomize All
This will randomize all spirit battles using the seed provided (or a random seed if none provided) and create multiple randomizers rooted in the same seed.
These results can be dragged into your Arcadia mod folder (most likely /ultimate/mods) and enabled/disabled with Arcadia.
Select your battle from the top dropdown. The first tab is for settings specific to the battle, the next tabs are for settings specific to the fighters.
When done making changes, select:
File -> Export
You'll see three options:
Packaged: Saves a "ready to ship" version of your mod with modified spirit battles, modified spirit images, and other supported modified files (Custom events as example) which can be loaded straight into Arcadia.
Standalone: Saves an unencrypted file containing your currently selected Battle and Fighters. This can be shared with others who wish to import custom battles from multiple people.
PackagedAndStandalone: Do both!
You can also import battles from a folder into an existing SpiritBattle DB. If you wish to play others Spirit Battles, you can place them in the Custom Battles folder, and Import Battles from the folder.
File -> Import...
All options for dropdowns are pulled from the loaded ui_spirits_battle_db.prc. This means that as new Smash updates come out, you should be able to replace the file and get new parameters loaded automatically.
If spirits_battle_event.prc is in the Preload folder, it will be used to populate Event types and labels. This means you should be able to (if done correctly) generate new events that will load organically into the program and into the randomizer.
You can modify the YesWeDo.dll.config file to change some settings and modify directory locations.
