These save files are required to unlock true zenorian mode.
A fire emblem like permenant death / ironman mode.
It also includes small gameplay changes all over, 
IE enemy stats are diffrent between expert and true zenorian mode.

Delete ALL your existing saves, 
then copy the files from New Saves folder to the games save location.
(For yuzu, right click the game and select open save data location)

You need to delete all your saves, and use ONLY the saves provided, 
because this game didn't code the save screen properly. 
Instead of it actually scanning the save folder for save files,
it only displays saves it personally created.
This means you also can't for example, rename save 3 to save 4 to move it.
Because it will save its save 3, try to load it, then crash.
Maybe a future update will fix this? 

Speaking of updates, these saves were made in game version 1.01,
but make sure to update your game to atleast v1.05.
It's undocumented, but it fixes a save corrupting bug,
regarding disbanding mercenaries while defending a village. 
(It has actual additions as well, but save corruption is more important)

Unicorn overlord has 2 pointless battles before the start of the game.
You can still get true zenorian from starting a new game, 
but for experienced players, loading save file 1 will skip you past them,
and take you directly to the difficulty selection screen before battle 1.
