randomspot555 edit: Because it apparently hasn't been clear enough, this thread is strictly for reporting ERRORS in PokeCheck's Legality Analyses. Anything beyond that is off-topic and may get you an an infraction.
evandixon edit: Because this thread is for reporting errors, this is also NOT the thread to ask why your Pokémon aren't legal. Be sure to search for legality guides before asking somewhere besides this thread.
Until the release of an update to Sabresite's legal.exe, I have added a basic legality checker for generation 5 to Pokécheck.
This tool is meant to detect edited or cloned pokémon. In accordance with ProjectPokemon's policy on hacking, you are reminded that edited Pokémon are not allowed on Black & White Random Wifi matchup and in all nintendo or affiliated events. As such, any request to make a Pokémon legal for Wifi or any official or non official tournament will be ignored and can get you banned by the moderation team.
To try it you can either deposit the pokémon to test on the Pokécheck GTS or have an account and import the .pkm file.
For a legit pokémon you should expect somthing similar to this:
Please report any pokémon either incorrectly reported as hacked or new ideas to detect currently undetected hacks.
Always include a link to the incriminated pokémon if you can. You don't have to make it public.
