Talk:Pokémon data substructures (Generation III)

The "Order" section must be wrong. When I calculed Personality 3935877326(in decimal) by 24(decimal too) I got "14" - which correspond to order EAGM - but something was wrong. After 4 hours intense counting and trying I realized the ordering was wrong. The correct ordering was GEAM . Game version: Ruby (US version) Pokemon: First in party Myself: ICQ: 343370964 . btw: Now I am stuck at recalculating data checksum. If somebody know... please...

I have solved your problem. 3935877326 turns to 0xEA98B8CE in hexadecimal. You have to use little endian, to which the rule applies, least significant byte first. In other words, the very last byte will end up being first. Rearranged as follows

0x1234ABCD -> little endian -> CDAB3412. So your number should be 0xCEB898EA, or 3468204266 in decimal. 3468204266 MOD 24 = 2, which is GEAM. Nice? Twigpi 20:51, 29 October 2007 (UTC)

Also, the checksum loops. Adding the unencrypted values should give you a value greater then 0xFFFF (max size), so it just loops. To find the correct value, MOD by 65536 (decimal) or 0x10000. Twigpi 20:51, 29 October 2007 (UTC)

Substruct encryption

If you play in an emulator like No$GBA or VBA, you can open a RAM viewer. Sometimes, if you look at a Pokémon data structure, you can see the encrypted substructs change values in a flash. This is because the game decrypts the whole thing for use and encrypts them again immediately afterwards. I always did wonder how it was supposed to use the data if it's encrypted... --Kyoufu Kawa 16:52, 31 July 2007 (UTC)

DVs

Investigation of Fire Red assembly code reveals that the DVs field is not exactly as described. More to follow. --Kyoufu Kawa 20:06, 10 August 2007 (UTC)

Little Endian

Using little endian. This means for every word (two bytes), you reverse the order of the bytes. The encryption and decryption will work as long as you keep the order the same for the key and the data. Twigpi 14:01, 29 October 2007 (UTC)
