I just stumbled upon this hack today and am enjoying it immensely. I do have a few questions. 1. Are the Pikachu-Colored Pichu/Spikey-Eared Pichu in this? As wild/events/anything? 2. Does catching Celebi activate the Silver/Giovanni subplot? aaand 3. I noticed it earlier in the thread, is there a problem with Gracidea? Does this mean I'll be unable to make Shaymin Sky Forme?
The first one will require pokesav in order to add the proper pichu (forme + shiny + fateful encounter) to the party.
For the second one, the caught Celebi is neither a fateful encounter one nor does it have the identifiers of being an event one - the caught Celebi need modification in pokesav in order to trigger the Silver/Giovanni quest.
For the third one, use pokesav to set the caught Shaymin's Fateful Encounter bit. The Gracidea can be acquired as usual then.
In short, use pokesav to modify existing pokemon for (2) and (3) and import for (1).
HG/SS pokesav works, but you need to use a hex editor for modifying the quantities of certain items, such as the Covenant Orb and SG/SS-specific key items. The save file is little-endian and CRC checking is used for validation, so open & save in pokesav to recalculate the section CRC, or you'll get a corrupt save message when starting the game.
