1. natures being uneditable with pokesav has nothing to do with the hack, the hack modifities the ROM itself, the save file structure remains untouched even if he edited the ROM natural scripting and engine it shouldn't affect the save file structure, meaning that the save file can be used even if the ROM is clean (unmodded, being reguler HG\SS), maybe you are doing it wrong with pokesavyeah, I ordered an Acekard 2i anyway I looked it up first and it was recommended over R4 in almost every case I saw so...
ANYWAY......because I want to stay on the topic of the thread I have a few questions for Drayano (or anyone else who might know) 1) Why aren't Natures editable in Pokesav? Or is that just a problem I'm having? 2) Can u find both forms of Shellos in this game? If so where because idt the document specifies? 3) Can u edit the Gender Ratios of Eevee, Togepi, and Chikorita to 50-50? I really want female Togekiss, Meganium, Espeon, Glaceon, and Leafeon and I never understood how Togepi could be considered masculine lol 4) Last question, is there any way to edit the items your Mom buys with your money to be a bit less...y'know...useless?
2. shellos was made in the pokedex with both forms, both forms available naturally in the ROM itself (I obtained them) at the same place
3. gender ratio can be edited, yes, the "swarm" has its own code of "appearence", the same values you get while loading\changing a pokemon in pokesav he can change, everything that doesn't have to do with the RNG, and even RNG he can affect, simply adding to the pool more "availabilty" to male\female is a value change on 16bit address, however "obtained" pokemon has either two forms of being "already written" or "having data structured by the RNG", mostly are the first form, I am not sure if gender value is part of the second form but if it's not, it's part of the script, which is changeable but very difficult to access and read (first to find) unless he uses some kind of decrypter (if it even exists as of now), but possible - it is
4. I think the items mom buys you are not scripted, I actually think they are part of the engine, they exist in the ROM code but it is very tough to find them, it's possible to change them since they exist, like changing values of special encounters (ex level of zekrom, it's simply finding that address and value that "talks" about Zekrom and reading on till it "talks" about the data of Zekrom ".pkm" structure and within it, the level, and to change it) I am pretty sure Mom's items are nearly the same way but finding Zekrom is easier as his "encounter" address is not as difficult to find, to find that "scripted" in the engine code of Moms buying (and all the other pokegear-item related contacts) you need to actually search for the values of those items and keep on searching until the syntax and the "rest of the garbage" around it sounds like it's the code and start poking and testing with it (changing the value to another value and test if the result are as planned), I believe it's very possible and once we find the value, the address is a poking-time away, the value I imagine would be easier to find if we guess on 2 items code (meaning it being 2x8bit code = 16bit code = 4 hex string searching all over the ROM, again it's kinda heavy, the entire ROM is 256 megabyte, which is 2048 gigabit, we are looking for specific string of 16bit code, with hex editor it's a minutes of work, but I don't know how much Drayano works well with hex editors (of course you could say that we could "delete" the zero'ed cartridge part of the ROM and decrease it to 160MB zone, process which is called trimming, but that still doesn't change the fact that Drayano needs to know how to work with specific tool to do that)
