Uuuugh!
Apparently Always shiny and Shiny rate modifier behaved very differently when it comes to different hex bytes for shiny lock,
Turns out that 09 is exactly the same modified hex byte as SM version that's not shiny locked can be encountered as shinies normally with both normal and modified shiny rate works but doesn't work with always shiny patch.
While 01 is shiny-locked you can't get them in normal ways even with normal/modified shiny rate, but will be unlocked when applying with Always shiny patch, I believe that's how Ash-Greninja is considered not shiny-locked but still shiny-locked regardless, that's quite strange.
02 and 03 are permanent shinies for ordinary pokemon that appears in the ultra wormhole, or Event pokemon even if it's random they retain their shininess after resetting the game, yet that still affects shiny-locked mascot legendaries, tapus and gift totems.
18 is well the original hex byte as always which is shiny-locked normally, duh.
anyways, gotta bang my head on the desk.
If you guys have godmode9 I advise you to edit the code.ips in Luma/titles/[titleID] in Hex editor, look for ''00 01 01 45 4F 46'' which is Shiny removal patch if merged with other ips patches, edit the third hex byte whatever you want to change, I'm not going to bother to fix that again, I'll leave that be that way. ^^;
