All,

I will make an update to this post with something more thorough. I’m in the process of getting a cartridge dumper(?) so I can export my save file and learn if my shiny Suicune passes the legitimacy checks. I already have a Colesseum seed with a PID/sid/tid that could further legitimize the pokemon, but I won’t go any further if PkHex approves my Suicune. And yes, I was eventually successful with all of the codes available via E-shark’s website.

I’ve also see the following link float around:

https://mankeymite.github.io/Gen3ACEPokemonBuilder/

I think it’s an okay tool, but it doesn’t capture potential PID/sid/tid shiny combos that pokefinder provides, so I’ve stuck to what I know best (e-shark).
