So Gen 4 (and I assume 5) have the same 16-Bit Species limit as Gen 3 (65536 avaliable species) also anything past a valid Mon species crashes the game due to lack of sprite
So your would be bottlenecked by a dex of 250 or so Mons despite the better hardware (unless you could expand the species field)
Generally speaking Stats in pokemon are recalculated when your Mon levels up (to applied level up growth and Evs) or when stored in the PC (Mons have extra data attached when in your party, that data can be easily modified like in pic rel)
Pic rel is a Regigigas with stats that go way higher than the soft cap and a different ability
