Sorry for asking in a 3 year old thread, not sure if someone will reply but thanks for PKNX and I heard it is possible to change shiny rates in LGPE using this. I can even see the button for same but whenever I click on it this exception occurs.
'Unhandled exception has occurred in your application. If you click Continue ....
Exception has been thrown by the target of an invocation.'
Strangely enough I get this error only for TM, Shiny rate, Type chart, others work fine.
I have used Yuzu to dump the RomFS
