Hey all! This thread will be used to preserve and figure out how data works for the Gen II games. Here is what has been documented. Pokemon Gold/Silver: (International) (Japanese) (Korean) Pokemon Crystal: (International) (Japanese)

I have a quiestion about third generation.... Mean while generating pokemon PID and IV's, i learn about the different methods to make this, for example: Generating 16 bits numbers i get the following [A321], [CC32], [3421], [E443], [3444], [EFAC].... (Only for example). Now i assign a letter to each 16 bits number: (Only for example). [A] [C] [D] [E] [F].... [A321], [CC32], [3421], [E443], [3444], [EFAC].... Now for the method 1 i get this: [PID] [PID] [IVs] [IVs] -> [A321], [CC32], [3421], [E443] -> ABCD for the method 2 i get this: [PID] [PID] [xxxx] [IVs] [IVs] -> [A321], [CC32], [E443], [3444] -> ABDE and for the method 4 i get this: [PID] [PID] [IVs] [xxxx] [IVs] -> [A321], [CC32], [3421], [3444] -> ABCE the question is... What about all others configurations? [ABCD][ABDC][ACBD][ACDB] [ADBC][ADCB][BACD][BADC] [BCAD][BCDA][BDAC][BDCA] [CABD][CADB][CBAD][CBDA] [CDAB][CDBA][DABC][DACB] [DBAC][DBCA][DCAB][DCBA]

Well, I was starting investigating this and then I discover that someone got it almost done XD However, I got some curious things, although my knowledge is far inferior from yours. First of all, sometimes I got an item that I had already received, so I thought that there should be two separate log check lists: one for Stadium 2 and other for IR. So, I started to investigate with PkHex and the event flags. I discovered that the items started at 0678 with the polkadot bed and checking the consecutive offets (like 0693 for Nintendo 64 and 0703 for Diglett doll) I could obtain all the items. However, if I unckeck these flags, I get deleted all the items that I had from the beggining and the ones obtained from my mother or through Stadium 2, keeping the ones that I have obtained through IR. Could you explain this for me? Also, congratulations for the great work! Regards.

don´t worry about capturing the sprites. On February 10, I will make a new post and say what I am going to capture. I will try to cover all the missing sprites, not just the backsprites shinys of gen 7

The different methods are a byproduct of something called vblank. Vblank is an interrupt function that happens as a result of screen rendering and it executes an RNG call. During wild encounters, the game picks a nature, then keeps rolling PIDs until it finds one that matches, then generates IVs. There is almost always a single vblank (dead RNG call) between battle start and the chosen PID. Sometimes two vblanks if enough PIDs are rerolled. Other times that second vblank happens during the PID roll. Theoretically could be between the PID halves, between the PID and IVs, or the IVs themselves. Method 1 is 0 or 1 vblank before PID is chosen.(often referred to as Method H1) Method 2 is 1st or 2nd vblank between PID halves. (often referred to as Theoretical Method H3). This method is so exceedingly rare (nobody has reproduced one or found one in the wild) it is skipped where Method 3 is often called Method 2. Method 3 is 1st or 2nd vblank between PID and IVs. (often referred to as Method H2) Method 4 is 1st or 2nd vblank between IV halves. (Often referred to as Method H4) The order is always the same (hence no CDAB). You can find it in PKHex's legality, including battle chance, first party check, nature confirmation, etc.

I guess I could even code the seeder as nds hombrew for convenience... didn't think about it since I made all testing on emulator.

The game has been reverse engineered, so it should be easier to directly check te code, then search the flag in the save; or just the old "save before and after" to check for diferences and try locating the flag https://github.com/pret/pokecrystal

not quite sure how to check that. I only really have Pokemon Sun and Us for my new 3DS and only exported saves for Sun. The folder layout is pretty much this: [Folder: Checkpoint] [Folder: Pokemon Sun] [Folder: CurrentSave] main [Folder:Backup] main I wouldn't think the backup would be affecting it though.

Probably because cheats were used on the save file. Hold control when opening the save to bring up the version override selection.

while the games are able to communicate normally (original GB) and on emulators, VC blocks ENG Gen I/II and KOR Gen II from communicating with each other.

@HaxAras had attempted to buy the Red cart back in May, but to no success. That's actually how I found out about this, but didn't get around to help have it dumped until recently. When he told me about it in September, he had mentioned the Blue cart to me from their talks, and iirc, the savefile was erased. It won't hurt to confirm it though, so I'll ask.

These are Japanese Pokemon transferred by Poke Transfer and Relocator. These are extracted from the used Japanese Pokemon cart save. Poke Transfer Pokemon.zip

Alright, after literal hours of going though a tedious process to find offsets, I finally managed to uncover the data for the Japanese and Korean versions; Glad there's no Crystal in Korean, that lessened my boat! XD But do note that I can't completely confirm some things such as Mystery Gift as I don't have access to the games of those languages for 3DS VC, so that's where you researchers with those copies can come in to clarify if they're on point, as well as any other data that you think is invalid/incorrect. Also still need Mom's savings in Japanese and Korean. As a bonus since I'm feeling nice today, here's the hex data line for one of Carrie's teams from Stadium 2: 32 9D AC 81 2B 6C 32 63 98 0B 0C 6A 32 65 57 81 CD 71 32 D4 E8 A3 61 74 32 E9 A1 3C B0 9F 32 A6 81 08 5B DB @theSLAYER I found the offsets a while ago for the GS INT (and speculated the Japanese and Korean offsets). I tried modifying the bytes of the ones staring at offset 1XXX, but they didn't seem to do anything (also couldn't find any hint of the Japanese ones stored twice), modifying the ones at 2XXX worked: I changed Raikou at offset 2B82 to TTar's byte and it was on its dex entry as a roamer! But anyways, here's my docs: GS INT: Raikou: 13E0 and 2B82 Entei: 13E7 and 2B89 Suicune: 13EE and 2B90 GS Japanese: Raikou: 2AE6 Entei: 2AED Suicune: 2AF4 GS Korean: Raikou: 182C and 2BC4 Entei: 1833 and 2BCB Suicune: 193A and 2BD2 Didn't look at Crystal since it's different with Suicune not being a roamer, but I assume you're looking at it?
