Current status of XD/Colosseum legality checkers and info?

[BLACKBERREST3]

I've read from another source that pokefinder may not give an obtainable IV/Nature/PID spread when generated. Do I have to use xdxheck/xdpokemon (https://web.archive.org/web/20180128112937/http://www.geocities.jp/ginzaru_xd/) or are pokefinder 4.2.0+ and PKHex accurate enough to detect legal spreads. Also, what pokemon are shiny locked in this game? I'm reading conflicting answers. Has anyone attempted to RNG a supposed shiny-locked pokemon with a known seed/frame in dolphin?

I'm guessing "shadow locked" either means that a pokemon's rng is locked the first time it is loaded in OR it means that it is shiny-locked because it rerolls the PID when snagged OR it means both of those things?

Also found another useful guide: https://github.com/TuxSH/PkmGCTools/wiki/A-guide-on-how-to-make-legal-Colosseum-or-XD-Pokémon

Most reddit guides have deprecated links.

 

TLDR: What is the current consensus for shiny-locked pokes and on how to check legal IV/PID/Nature spreads in XD

 

I am halfway through XD. I'm playing it again because I never beat it as a kid. Even as an adult, I still got lost because I skipped through dialogue that tells me where to go next. This game has TERRIBLE direction! And I love it! Someone needs to make a fan game or rom hack of battle bingo. That sh!t is fun.

Read more carefully through this. It appears that shadow pokemon can definitely NOT be shiny.

 

and pkhex checks for this
