| I've been trying to read and display pokemon data directly from the ROM file, there are a few things that are puzzling me.
I noticed that while the games have what seems to be a fairly random order for the pokemon index numbers, the pokemon data starting at 0x383DE in the ROMs is in order by pokedex number. Giegue's Master Guide to Hacking Pokemon Games Red-Crystal says this is the format of that data: 27 bytes total: 1st: pokemon number 2nd: HP rating 0-255 higher is better 3rd:ATK rating 0-255 4th  EF " "
5th: SPEED 6th: SPECIAL 7th: Type ##1 8th: Type ##2 9th: Rarity factor 0-255, higher is rarer 10th: EXP factor, 0-255, higher is more points 1th: Picture size? (not completely sure how this affects the picture) 12, 13: Pointer value for picture facing you (enemy) 14, 15: pointer value for picture facing enemy (your pokemon) 16-19: attacks known at level 1 20-27: Which HM's and TM's the pokemon learns. (probably 64 binary switches in order) What I can't seem to find is how it determines the growth rate - how much experience per level a particular pokemon takes. The experience field in the data block doesn't seem to have anything to do with that, and a mechanics guide I read said that it's only used to tell how much exp a pokemon is worth when it's defeated in battle. I've found plenty of player's guides that list what the rate is for each pokemon, but so far I've had no luck with grabbing it directly from the ROM. After I noticed the orderly organization of that data I looked around and found that I couldn't make sense of most of the other block data in the ROM. The list of pokemon names appeared to be in the strange index order, but beyond that a lot of the information looked like it was in complete disarray - not following the pokedex ordering or the index numbers. Ahh, that was a lot. So what I'm asking is: How does it store what the growth rate of each pokemon is, and how can you calculate the proper order for things that don't seem to have one? Attached is a win32 console application that displays the pokemon data at 0x383DE, and the inaccurate name since the name array is not in the same order. I hope to expand it to display all of the pokemon information accurately reading directly from the ROM. Syntax is: pkmnutil <romfile> <pokemon number> |

also, I have a set of math formulas used to calculate various things in the original games, it might just be what you're looking for. Let me know if you're interested, I'll have to dig around for it a bit.
