Hello ProjectPokemon community, Today I want to share with you what I found about reconstructing a long lost Pokémon using ONLY the information the game has stored on a Secret Base. It is important to know since the beginning that the game does not store IVs for Secret Base teams, but it does store their pokemon's PID, which can be used to find some possibilities for the IVs. This has been tested on Pokémon Emerald ENG. So, without further ado, lets begin. Tools needed: VBA PKHex: TriggersPC: PKX Extraction: PokeFinder: https://github.com/Admiral-Fish/PokeFinder/releases First of all, we need the savefile loaded into VBA. Get in front of the trainer that has the Pokémon you want to reconstruct, and create a savestate if you want. Initiate the battle with the trainer, and let him throw his first pokémon into battle. Then, go into Tools -> Memory Viewer. Click Save... Fill both fields with the following: Address 02024744, Size 300 This will create a memory dump with the information of the trainer's pokémon team. The next step is to use the tool PKX Extraction. Select Main Line Games, Gen3, and open the file you just dumped from VBA. Click Extract, and you will be able to Save each Pokémon as a pk3 file. Now lets open TriggersPC to find what is the TID and SID of the OT. In the top bar select Games -> Manage Saves and add your game savefile to the list. Click Close. On the top right select your savefile, and click on the Secret Bases tab. Select the trainer you want to get the TID/SID from and you will find both values in the bottom left area. Take note of both TID and SID values. Now into PKHex. Open your savefile into PKHex and drag your pokemon into a box. Right click it and select View. In the left side of PKHex, you'll be able to input any value you want into any field provided. Before that, lets grab this pokémon's PID right at the top. From here, we 100% know the pokemon's PID and Nature. This crobat has a PID A4B7983E and its Hasty (Nature is tied to the PID). Lets go ahead and click OT/Misc on the left side, and input the OT Name, ID and SID (we got them from Triggers PC). It is now time to start with assumptions, unfortunately. Do you remember Met Location? Do you remember in which game the pokémon was caught? That might be important... I know this Crobat was caught in Ruby ENG, with a live battery (not dead battery). I know this because my friend David was the first from our group to own a gen 3 cartridge back in the day, and I know this is his first savefile. So it is very likely that this savefile was created while the battery was still alive. I don't know where this Zubat/Golbat was caught, tho. All this information would help you narrow down the possibilities for finding the real IVs combination for this Pokémon. Lets go ahead and open PokeFinder. Click on Gen 3 Tools and then PID to IVs. Input your pokemons PID and click Generate. Your results may be different, but in my case I found 3 possible IVs combination for this Crobat. Now, Method 2 for wild Pokémon, is typically an Emerald thing. Method 4 COULD happen, but its less likely. So, we are left with Method 1. I would say that I am 90% certain that this pokémon was generated via Method 1, but there's still a chance it was Method 4. I am not sure, so I'm playing with statistics. Feel free to check the cheat sheet at the end of the guide for a more comprehensive list of methods per encounter for each gen3 game. Lets go into PKHex and input the IVs into our pokemon. Since we are here and the EVs are not real (they were created by the extraction tool) lets clear them all. We are just left with one question. Where was this Zubat/Golbat caught? Well, it can be caught in the following locations. Zubat: Cave of Origin Entrance & Floors 1 & Basements 1, 2 & 3, Granite Cave Floors 1 & Basement 1 & 2, Meteor Falls Entrance, Seafloor Cavern, Shoal Cave, Victory Road Floor 1 Golbat: Cave of Origin Floors 1 & Basements 1, 2 & 3, Meteor Falls, Seafloor Cavern, Shoal Cave, Sky Pillar Floors 1, 3 & 5, Victory Road Floor 1 & Basements 1 & 2 You can use PokeFinder to search for it. I was lucky while writting this guide, and I got a possible Zubat at the first attempt. Lets see how I did it. Go ahead into PokeFinder and on the startup little window, click on Gen 3 tab and then Wild option. Then, on the profile section at the top, click Manager and create a New profile with the correct information. Check the following screenshot to see how I did mine. I didn't check Dead Battery because, as I said before, I believe this Zubat/Golbat was caught on a live battery. Now, back into the main window, select the profile we just created. Don't miss this step. Click on the Search tab, and input the information you want to search for. In my cause, I searched for a wild Zubat using Method Wild 1, in Cave of Origin 1F, with the IVs I found previously (min and max), I set the gender to Female, and I set the Nature to Hasty (I knew this information was 100% correct from PKHex - again, PID and Nature are tied). Then, click Search on the left. If you get no results, change the Pokémon filter if applicable (in my case Zubat or Golbat would be possible), and if not, change the Method. If you still get no results, change the location. Mess around with all those filters to try to find your pokémon. The PID of this result matches the one I extracted from my savefile's secret base. Now, back into PKHex, input the Origin Game, input the met location you are happy with, and input the Met Level that was returned by PokeFinder. Click the red triangle at the top left of the pokemon, and it should be legal now. And there you go. Now click on the illegal pokémon thats left into the box, and select Set. It will be replaced by the legal version that we just reconstructed. DONE! Cheat Sheet for Methods (provided by Papa Jefé) All Gen 3 Eggs More-or-less untraceable.
