Well if it's an IPS patch, you can use a Lunar IPS program. It basically writes the changes (as dictated in the patch) into a copy of the file that should be change (which in this case, is a ROM).
I'm giving you the benefit of doubt and assume you're asking for a patch.
Asking for ROMs are against our rules.
Anyhow, I *think* there's a program that can modify shiny rates. look for it online.
If you downloaded the XCI from the web, then that's piracy.
Well, it is against our rules to associate with piracy, and do understand, we cannot assist you any further.
There you go. “Base”.
if your game wasn’t “base”, you won’t be able to produce a “base” save. Dump the update from your Switch, then install it on Yuzu.
If you’re trying to track “what you’ve obtained”, then it’s possible.
Going back to your party question, if you know the save structure, and how to read your party, then you can add it to the list. It’s gonna need effort.
I assume you’re looking at base game. Those legendaries did not exist in v1.0.0 and only came into existence in SWSH with v1.3.0. Making mons where their species were cut results in that.
That way of describing it may be misleading to those that didn't read everything up until now.
To clarify to others, there's nothing wrong with the wonder cards. It appears to have been simple user error.
Use TrainerID7 and TrainerSID7 instead, if you're trying to use that format.
The method of obtaining these will not be disclosed.
However, I *think* it's public information, and you can search for it on your own volition.
(Don't bug me or our forums, in any form or way, direct or indirect, about these)
