The internal data of GC games for purification for shadow pokemon does not have values from 0-non shadow to 100-total shadow, it have values sarting from the initial shadow hearth gauge to 0-non shadow.
Remove duplicated SAV pkm set method (byte[] instead of PKM, was unused.
All it did was getPKM(decryptPKM(data)).)
Tweak Seen/Caught count expression body to use the HasPokeDex bool, as
GB(A) games did not use the PokeDex int offset. Things were simpler back
then :)
Remove unnecessary toarrays
fix 3->4 items being deleted even if they were valid
be nice and allow held item to transfer 4->5 if it can still be held
invert purification values, heart gauge is [-100,0] not [0,100]
