Primo is the dude in the Violet City Pokémon Center who used to host the
Teachy TV programs and now sits around asking passersby what they think
of him or whatever. If you tell him the right phrases for your trainer
ID, he'll give you an egg. See: http://www.filb.de/games/tools/aikotoba
This had been done before, but some of the changes were lost when I
re-ripped Diamond and Pearl.
Also, Turnback Cave has been collapsed into seven sections rather than
four. The previous change in particular ignored that the encounter
rates for the first three areas were lower than elsewhere. I'm
conjecturing wildly, but I believe those first three are the actual
pillar rooms, and the following four identical groups are the groups of
rooms between the pillars.
Great Marsh is now Great Marsh instead of Safari Zone.
Ruin Maniac Tunnel has been consolidated into one location, and the
areas are actually named informatively.
Turnback Cave has more appropriate area names.
Routes with two parts now mention the cardinal direction in the area
names. Also, several town names have been fixed.
Lake Verity's area names now mention WHAT they are before/after.
Finally! Location order is the same as from the old dex, which was
something like the game but ultimately arbitrary, so it's not any better
now.
This takes a very different approach to storage, rather than copying the
game exactly and trying to fix everything in code. Comments coming
shortly so other people can actually make use of this.
