liaF cipE Posted September 25, 2011 Share Posted September 25, 2011 As is probably evident by now, I really do not know a lot about what I am doing, mainly because my programming experience is with stuff like C++ and Java… Yes, I do know basics like what hexadecimal is, AR codes are CPU instructions, etc. But I lack on some of the more advanced stuff and notations, and I am not sure of exactly where I stand in terms of how much I know. For example, I don’t really know what 00013 022349D4 d h 0 Slot1 PID(W) means, or how I can change that to give the hex address/1st chunk in an AR code line (Is it 022349D4? Does that number need to be changed somehow?) As such, here is a list of what (I think) I know, and what I need: Know: -The main portion of the code will be from assembler, which will read and write values from hex addresses on the cart’s RAM, dictated by setting the Hex address for a value as the absolute address in the assembler code -The assembler code will also read and write values on to the AR itself, (like R1 and stuff) which should have the right value when used with a complier designed for the AR. (I’m not entirely sure about this bit, and I suspect I will have to temporarily store values somewhere on the game’s ram, like the output of a sum that I need to modify more before it goes into another spot on the cart) (If anyone knows a good assembler compilier for the AR/BW, I would be glad to know ) -I am using this nice code from Bond697 to run the assembler code on the AR: 94000130 FFFB0000(run on hitting select, can be changed to whatever) 023FE074 012FFF11 E0000000 0000XXXX(the Xs here are the number of bytes being run in total, 4 per word) AAAAAAAA BBBBBBBB CCCCCCCC DDDDDDDD EEEEEEEE FFFFFFFF GGGGGGGG E12FFF1E Which runs the code from the AR memory, so there are no issues with storing the function somewhere -Lines in the AR code that change a value at a hex address like 12234A44 0000XXXX change the value at the hex address 12234A44 to 0000XXXX, so I can have 12234A44 as the absolute address in assembler and have the assembler code read and write to the same place as the AR code. (I’m not 100% on this. If the 12234A44 value needs to be modified to give the hex address, please tell me what the formula/algorithm is to transfer from 12234A44 to the proper hex address) -How to write to the values of the 1st pokemon in the party for current and max HP, Atk, Spl Atk, Def, Spl Def, and Speed, which is done by inputing the number I want xored with the value for 0 (got it from pokegen) at the following hex addresses I got from Delta Blast Burn (in AR code form): 12234A42 current hp (lucky guess on my part) 12234A44 atk. 12234A46 (max) hp 12234A48 def. 12234A4A sp. atk. 12234A4C speed 12234A4E spl def -(I will be fine with the writing of the assembler code and the algorithm of the code once I have the info I need. I don’t know all the syntax off the top of my head, but I know where to get any help I’ll need with the stuff pertaining only to assembler) Don’t know: Note: If some sort of short hand notation/formula is used as an answer, that’s great, but please also include how I go from the short hand/formula to the thing I need, like the hex address. Also, a resource where I can get the information from is fine as an answer. (As you may see, I need a lot of hex addresses. I thought I could use pokegen, which worked fine for the stats, but for most of the values I wanted changing one of them altered the same 30 lines of AR code each time, so I had no idea how to isolate each individual variable. Ie: happiness, nature, ivs and evs all changed the exact same 30 lines... :confused:) -The hex address (read) of the nature value for the 1st party pokemon, and how to transform the raw number into something more usable. (Is it the encryption thing with the PRNG?) (I found something that says it is the 41h value, but I have no idea what to do with that) (I think the fixed numbers should look like this: 0x00Hardy 0x01Lonely 0x02Brave 0x03Adamant 0x04Naughty 0x05Bold 0x06Docile 0x07Relaxed 0x08Impish 0x09Lax 0x0ATimid 0x0BHasty 0x0CSerious 0x0DJolly 0x0ENaive 0x0FModest 0x10Mild 0x11Quiet 0x12Bashful 0x13Rash 0x14Calm 0x15Gentle 0x16Sassy 0x17Careful 0x18Quirky ) -The hex address (write) for the happiness value of the 1st pokemon in the party, and how to change the value I want before it is written to that address. -The hex addresses (read) for the iv’s and ev’s of the 1st pokemon in the party, and how to transform the value to give the proper number. (ie 31 or 252, not 0x8F72 or something like that) (Does this use the encryption?) (I also found stuff here: http://www.projectpokemon.org/wiki/Pokemon_NDS_Structure#Unencrypted_bytes but I do not know what to do with those to get the 1st party pokemon hex addresses) - The hex address (read) for level, how to tranform the value into the actual level, etc.. If it helps, the code will only be used on pokemon made in Pokegen, so things like location and PID will be constant. The code just needs to be flexible wrt level, iv, ev, and nature. I thank whoever helps me in advance. (Especially since it will probably be the same people, and I’m sure they are starting to get annoyed by now…) Link to comment Share on other sites More sharing options...
Bond697 Posted September 25, 2011 Share Posted September 25, 2011 everything you want to change is encrypted. since you're proficient with java/c++, your best bet is to read about how the encryption works(i think there's a wiki article) and write an app to decrypt the pkm and the re-encrypt it so you know what values you want to change to what. however, if you want to somehow reuse an ar code that does this, that's a much different vastly more challenging story. is this something just for you or something you're making for a lot of people to use? if it's the former, doing so might be a bit easier. we can just cut out the encryption. e: well, you would need to use the cut encryption on a new game or edit all your pokes to not be encrypted. if everything isn't encrypted with the 4th gen rng, but the game tries to decrypt with it, Bad Things will happen. srsly.

This code is going to be used on just my game (although keeping the option open to spread to other games would be nice, it can be dropped if need be), and the only pokes it will apply to are ones made from Pokegen in the first place so I can get the pkm file and I can have PID (and location stuff, trainer stuff etc) remain constant. (even though the PID will disagree with the stats) Is the .pkm file structure the same as the wiki says it is here: http://projectpokemon.org/wiki/Pokemon_NDS_Structure#Encryption ? Also, pokegen says it can "ignore save file checksum". Would that actually change anything about the pokemon's code (maybe make this easier?), and if so would it still work in-game? I don't care if it would be illegal, but it still needs to not break the game . For the action replay codes I mentioned for stats (the 2nd half is 0000XXXX), I know they change the desired stat (I assume the encrypted value) to XXXX, and I can calculate XXXX to give me the right number in the stat. Am I right that the first half is the hex address, or is it something completely different? If it is different, would decrypting the .pkm file tell me what the right hex address is so I can use it in assembler? e: at the link above, it says the stats (and level, I should probably recheck pokegen (although exp using the other stuff ) are encrypted via the PID, which might explain why I could isolate the lines that changed each stat in the pokegen code. Perhaps the ignore checksum stuff in pokegen would allow me to isolate a line that gives the check sum, and what lines give the other values I want. However, I do not know if I am right about the hex address thing in the first place.... Also in X[n+1] = (0x41C64E6D * X[n] + 0x6073) from the link, are * and + bitwise operators? e2: nvm, the ignore checksum does not seem to change anything in the AR code.... (confirmed by Codr) e3: better link: http://www.projectpokemon.org/wiki/Pokemon_Black/White_NDS_Structure although it does lack some info, it is for B/W Edited September 25, 2011 by liaF cipE Link to comment Share on other sites More sharing options...
Codr Posted September 25, 2011 Share Posted September 25, 2011 Also, pokegen says it can "ignore save file checksum". Would that actually change anything about the pokemon's code (maybe make this easier?) That option only refers to the save file checksum. It has nothing to do with the checksum involved with Pokemon data. Link to comment Share on other sites More sharing options...
liaF cipE Posted September 25, 2011 Author Share Posted September 25, 2011 (edited) I just looked back @ a testing code, and it turns out that 12234A44 was max HP, not attack. In fact, I noticed that all of the endings are 2 away from each other, and (when fixed) the ording will probably be consistant with the pkm structure, as there too are the stats offset 2 away from eachother, with the ordering of current hp, max hp, atk, ... (I will probably double check this). If so, then I might be able to adapt those codes and the ones I isolated from pokegen that changed 2 stats (weirdly enough with the later stat first so AAAAHHHH where A is for atk and H is for max Hp. Current hp was in the first 4 digits in its line, further being consistent) to obtain general codes to fix any offset value in the file. If this is the case, how could recycle the code so I can get the hex addresses it writes to for the assembler code? Edit: It turns out that execpt the 1st and last line, the 1st 8 hex digits go in order, adding 4 each time from 0x022349B4 to 0x02234A8C, or a difference of 0xD8, which hits all the pkm offsets execpt the 4 at the end in the trash bites section. (actually, the last code hits the next 4 offsets in the pkm code, so it does get all of them) Edited September 26, 2011 by liaF cipE Link to comment Share on other sites More sharing options...
liaF cipE Posted September 26, 2011 Author Share Posted September 26, 2011 Alright, this is the only real important thing: By adapting the pokegen code with the encryption algorithm I can get AR codes to change the values in the pokemon data, calculate the encrypted value, as well as unencrypt a value and know what value is what. (In say a pokegen code) So, how can I transfer the AR code into what assembler needs to read at write to the place the code edits? :confused: Link to comment Share on other sites More sharing options...
Bond697 Posted September 26, 2011 Share Posted September 26, 2011 you would need to decrypt and re-encrypt the data on the fly. using the ar. in assembly. i can see this turning into a mess. i still don;t understand exactly what you're trying to do?

liaF cipE Posted September 26, 2011 Author Share Posted September 26, 2011 you would need to decrypt and re-encrypt the data on the fly. using the ar. in assembly. i can see this turning into a mess. i still don;t understand exactly what you're trying to do? Basically I want to read nature, ivs, and evs, perform a calculation, then output the values into the stats via assembler. The AR codes I have plug in the encrypted value for either 2 or 4 (or 1 if I'm right) values in the 1st party pokemon data. If I can get the hex address for where those codes write to and read/write there, I can have the code get the values into variables, perform the decrypting algorithm, do the calc/logic with those values, then reencrypt the values to put into the stats. Since PID is constant for ALL pokemon that get the code, I won't have block shuffling issues, and since the stats are encrypted via the PID I won't have issues with check sum changing. (plus I can read the check sum and PID as they are in the codes I can use) So it might be somewhat annoying, but it should be quite doable. The only issue is getting the hex address so I can get assembler to read/write to where the line writes. Am I right that it is the 1st 8 hex digits of a line that only writes in values?

After I use the one program to make a .bin from the asm source file, rename it to source and put it with asm to ards, putting in the code and hitting the button works just fine.

Bond697 Posted October 17, 2011 Share Posted October 17, 2011 you know what? i just tried the backlight code on my ds with an ards. it's an ar code handler hack too. it doesn't work. i'm wondering if, when they updated the ar firmware, they changed where in ram the ar code handler sits to accomodate the new dtcm(and stacks) the ds sdk now uses so that the ar would stay well out of range of any nintendo code. that would explain it perfectly. and it means that that ar hack isn't usable any more. that code i had you test should work 100% of the time, but it doesn't. that explains it perfectly. and really screws this over.

Thanks for the help though. Link to comment Share on other sites More sharing options...
