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

PKHeX is "complete" for validating a given PID/IV being obtainable or not, and considers shininess as well.

Only XD prevents shinies for shadow encounters.

Thank you.

Figured out how to use XDcheck. Turns out pokefinder is just as good now. I realized why my genned eevee wasn't showing up legal. It depends on the OT ID/SID. I appended "input('Press ENTER to exit')" to the end of the python script found here (https://raw.githubusercontent.com/wiki/TuxSH/PkmGCTools/colosseum_starters_legit_checker.py) so it doesn't just close the console right away. I heard there was a feature to auto-generate an ID/SID in pkhex given the PID, but I couldn't figure out how/where to get that so I ended up using this script instead. For clarification, eevee is synonymous to umbrion when using the script. Ty rinnegan and your post from 2017. This stumped me for a bit.

What does shadow locked mean?

The script you linked is old and does not handle the fixed gender requirements of the starter Espeon and Umbreon (both of which must be male, and never shiny). Since Eevee is 87.5% male, statistically it'll be "right" more often than not, but it will produce inaccurate results frequently. It works for Eevee, simply because Eevee is not locked to a single gender (and can be shiny).

"locks" are a community term for requirements/disallowed features. In this scenario, a "gender lock" is when a Pokémon is only to be generated with a specific gender, and the game generating loop is locked in a repeating loop until it meets the criteria. When an NPC's team is generated, it usually has non-shadow Pokémon before the capturable shadow Pokémon. These non-shadow Pokémon have their own requirements, that cause the RNG to loop until satisfied, being nature and gender locks. In XD, the developers also disallowed shinies from being generated for the NPC (and the player), hence a "shiny lock".

[BLACKBERREST3]

Gotcha. I'll keep that in mind when I'm playing colosseum. I couldn't find the trainer feature that was mentioned somewhere that auto generated a pid for the starter eevee. Is it a plugin?

Your explanation on shadow locks was pretty good. Reading it back now after a few more articles and smogon research threads, the "repeating loops" makes a lot more sense now. XD has some really complicated rng.

So if I have this correct, I think the pokefinder tabs were grouped between non shadow locks and shadow locks because of the way nature lock passing (NL Pass) and anti-shiny spreads works in XD

I think I got it figured out this time...maybe

[BLACKBERREST3]

I found out what anti-shiny and nl pass (nature lock pass) means! That was another term that eluded me. found it here:
