Hello. As stated in the title, I'm trying to modify HoF entries. It's pretty straightforward until block checksum recalculation - I've followed the same path as with general/storage block, i.e calculating CRC16 CCITT for the whole block right until footer part, but it seems that this is not the correct way, as every time I load such modified save, when selecting HoF in PC, there's a message saying that HoF data has been corrupted and in order to fix it, I should enter Elite 4 (or something similar, doesnt matter). I've tried recalculating the checksum and comparing it with one in the footer and it differs. Additionaly, I've downloaded this tool to play around with it a little more and this one does the job - entry is modified as expected and game properly loads HoF. So such modification is possible, how the checksum for Hall of Fame Block in gen IV is calculated?

Hello, I am currently working on a rom hack for pokemon black. One of the things I need to do is change the starter pokemon. I have searched this site and the internet for tools or hex editing tutorials to do this, to no avail. I do not care if it still says "snivy," "tepig," and "oshawott" in the selection screen. What I want to happen is if you pick the grass choice, you get chikorita, fire gives you cyndaquil, and water gives you totodile. Additionally, I want to make it so the dreamyard monkeys get replaced by the gen 1 starter of their respective types. Could anyone give me a rundown on how to do this?

Somewhat new this, I've been trying to get the old legendries into Pokemon Violet with no luck. (Moltres, rayquaza, mew, so on) Could some send me files of Legal ones, because I know their possible. Because I seen it. Also could someone maybe tell me how to make a legal one.

Hello, I wanted to create a shiny channel Jirachi with pkhex, but since I don't understand everything about pid and seed, I don't know if it's somehow possible to make the Pokemon legal. If someone could please check if the Jirachi is even possible and if it is please send me a .pk3 and .pk5 file I would be very grateful. The Pokemon should have these values: Shiny = yes Nature = Bashful lang = GER Origin Game = Ruby (Since I unfortunately lost my Ruby. ) If possible with the IVs HP = 23 Atk = 28 Def = 26 SpA = 20 SpD = 20 Spe = 31 OT = CHANNEL (Since it's supposed to be from Pokemon CHANNEL) For this I tried PokeFinder and maybe made a few helpful screenshots.

I know that if xor=0 pokemon can be square shiny. But I cna't find how to make sq shiny jirachi pk3 with pkhex. It's hard to match legit pid I tired Rng reporter to find pid but channel part doesn't match and pkhex database doesn't give shiny one. Is there any way to find legit square shiny jirachi pid? or get legit sq jirachi pk3?

I can't find way how to make legit tri attack togepi in gen3 Ii's hard to make legit pid & met location. Anyone who knows how to make legit xd togepi in gen3 plz tell me.

I'm finding tri attack togepi with serene grace from pokemon xd Someone who has legit pk3 file plz I need it

As we all know, if you want to migrate pokemon from Ruby/Sapphire/FireRed/LeafGreen/Emerald to Gen4, you need to use Pal Park to migrate. You have to insert Diamon/Pearl/Platinum/HeartGold/SoulSilver into slot1 of NDS(L), and insert Gen3 cartridges into slot2. Then from the start menu of Gen4 game you can find an option to migrate pokemon from Gen3. What needs to be noted is that: 1.For jap/eng/fra/ita/ger/spa Gen4 rom, Gen3 rom must have the same language as Gen4 rom to migrate. 2.For kor Gen4 rom, it can migrate both from jap Gen3 rom and eng Gen3 rom. So is there anyway for Gen4 rom to migrate from any region of Gen3 rom? The following are several methods for Gen3 Region Unlock (Reading this Guide requires some basic knowledge of hexadecimal and RomHack experience): Method 1: Hack GBA Rom header (Emu or GBA flashcart) Principle: Changer the Language code of Romheader. Practice: Take jap Gen4 & eng Gen3 as an example. 1.Open the eng Gen3 with a hex editor, you can see ‘POKEMON RUBYAXVE’ at address 0xA0. Below ‘AXVE’ you can see ‘0x41’ at address 0xBD。 2.Change language code: Since jap Gen4 is where we need to receive pokemon, we should make eng Gen3 rom like jap Gen3 rom. The ‘E’ of ‘AXVE’ is language code, so we change it to ‘J’-‘AXVJ’. 3.Change header checksum: While ‘E’ changed to ‘J’, it hex value also changed from ’0x45’ to ‘0x4A’, which 0x45 + 0x5 = 0x4A. So we need to change header checksum at address 0xBD, let ‘0x41’ minus 0x5, which 0x41 – 0x5 = 0x3C. So change checksum from ‘0x41’ to ‘0x3C’. 4.After that, this hacked eng Gen3 rom can be recognized by jap Gen4 rom through emulator or flashcart. Here are other language code (note capitalization): Japanese-J, English-E, French-F, Italian-I, German-D, Spanish-S. Method 2: Hack NDS language value (Emu or NDS flashcart) Principle: Let the language values which NDS use for checking GBA rom all change to the values matching NDS language. Practice: Take jap Gen4 (Diamond) & eng Gen3 as an example. 1. Use CrystalTile2 to open Diamond rom, search for ‘AXVJ’, you can find several columns of similar characters, 5 Gen3 versions, and 6 languages. Versions: Ruby-AXV, Sapphire-AXP, Fire Red-BPR, LeafGreen-BPG, Emerald-BPE. Languages: Japanese-J, English-E, French-F, Italian-I, German-D, Spanish-S. Combine a total of 30 corresponding Gen3 game codes. The following analyzes the structure of this table, using ‘AXVJ’ as an example, every 8 bytes in groups: ‘41 58 56 4A 00 00 01 00’ The first 4 bytes are the Ascii code corresponding to ‘AXVJ’, and the second half only needs to pay attention to the 7th byte, ‘0x01’, here as the language value Japanese to judge. The correspondence of language values: Japanese-0x01, English-0x02, French-0x03, Italian-0x04, German-0x05, Spanish-0x07。 When the Gen3 cartridge is inserted, the NDS side compares the first 4 bytes of the game code with gba haeder, and when it finds a value that matches, it returns the 7th byte (language value), and only when the language value matches the language value of the NDS game, the Migration option will be opened. 2. According to the above, you can know that as long as all the language values returned by 30 game codes are changed to the language values of nds, then Gen 3 games in all languages are compatible. In this ezample, the Jap Gen4 (Diamond) needs to change all 30 language values to 0x01 Japanese. 3. After saving edit, you can make this Jap Gen4 (Diamond) recognize the Gen 3 cartridge in all languages. It should be reminded that in the Rom of Diamond/Pearl/Platinum, these game code and language value are uncompressed, while in HeartGold/SoulSilver, this part of the content is compressed and cannot be directly searched to find, you need to decompress ‘overlay 9_0074.bin’ file (this file name is unpacked from CT2, the name may be different if you use other tools to unpack) to find the corresponding data, and after hacking, you also need to compress it. Method 3: Hack NDS asm code (Emu or NDS flashcart) Principle: Hack the function mechanism of Migration judgment. Practice: 1. At the beginning of the guide, it was mentioned that jap/eng/fra/ita/ger/spa Gen4 rom can only receive the same language of Gen3 rom, but Kor Gen4 can receive jap&eng of Gen3 rom. Therefore, there are essentially two Migration judgment mechanisms in Gen4 game. In Gen4 ROM, the file where the Migration judgment function is located is: Diamond/Pearl: overlay9_0083 Platinum: overlay9_0097 Heart Gold/Soul Silver: overlay9_0074 (1) Codes for Jap/Eng/Fra/Ita/Ger/Spa version (taking the pret project Eng HeartGold as an example): see this file and line number ‘/asm/overlay_74_thumb.s #L832’ (the following is the assembly code, If you don't understand it, you can skip it directly, see the description below). ——————————————————————————————————————— _0222767E: 0x0222767E 1C20 add r0, r4, #0 0x02227680 FF16F5F2 bl sub_0201A4B0 0x02227684 68A8 ldr r0, [r5, #8] 0x02227686 FF69F602 bl Pokedex_GetNatDexFlag 0x0222768A 2800 cmp r0, #0 0x0222768C D00B beq _022276A6 0x0222768E F99BF00C bl PmAgbCartridge_GetLanguage 0x02227692 4905 ldr r1, _022276A8 ; =gGameLanguage 0x02227694 7809 ldrb r1, [r1] 0x02227696 4281 cmp r1, r0 0x02227698 D105 bne _022276A6 0x0222769C FF98FF00C bl PmAgbCartridge_GetVersionInternal 0x0222769E 1C40 add r0, r0, #1 0x022276A0 6268 str r0, [r5, #0x24] 0x022276A2 FCE7F00E bl ov74_02236074 _022276A6: 0x022276A6 BD38 pop {r3, r4, r5, pc} .balign 4, 0 _022276A8: 0x022276A8 020F5670 .word gGameLanguage ——————————————————————————————————————— The code here roughly means about migration: 1) whether to obtain the national pokedex, if passed, go to 2, and if do not pass, ends; 2) Check whether the GBA Rom language value is equal and compare with the NDS Rom language value, if it is equal, go to 3, and if not equal, ends; 3) Check the GBA Rom version, which is displayed in the menu when migrate.

So what we need to do is to change ‘if not equal, ends’ to ‘if not equal ,continue’ . In two cases above, you only need to change 0xD105 to 0xD1FF, that is, you only need to change one byte 0x05→0xFF. After that the region restriction will be unlocked.

Method 4: Cheat code hack NDS asm code (Can use for Cartridge) Principle: Same as Method 3, but don’t need to change the ROM while this method change the RAM. Practice: 1. For codes of migration function will be loaded to RAM, so we can use cheat codes to edit RAM without edit ROM. It means we can apply this region unlock hack on Real Gen4 cartridges by using tools like Aciton Replay, NitroHax etc. (see video link Jap HeartGold migrate from Eng Emerald (Pal Park region unlock) ) I’ve made the region unlock codes written in Action Replay format for NitroHax and can also be used for emulator. You can download this file ‘cheats.xml’. Pal Park region unlock code: Diamond/Pearl: Platinum: HeartGold/SoulSilver: cheats.xml

So basically, I keep getting this error message every time I try to open my old Pokemon Black save file even on the latest version of PKHex. It's completely unedited as far as I'm aware but it just never works. It's definitely not just a PKHex thing since the save file won't load anywhere else either, like when I try to load the game with it nothing happens, so basically I was just wondering whether or not it actually is corrupted and if so is there anything that can be done about it. Just really want to know since I haven't seen this save since about 2012 as that's when it initially stopped working for me. I have attached both the PKHex error message and the .sav file itself for convenience and I hope something can be done about it. Cheers for any info given in advance. Pokemon Black (U).SAV

I've been digging into how it would be possible to edit the checksum on my Pokemon Sapphire savefile so that it ends up at A030 for a shiny (naughty) Jirachi from the Pokemon Colosseum Bonus Disc. Sites such as JirachiCalc have been useful in helping me figuring out my current checksum but that's about it. I've read a lot of older posts about using hexeditors and such but I always end up more confused and ultimately give up in the end. I'd apricate any help and possible explenations so I can understand and maybe generate other types of Jirachis down the line. My current checksum is at 3C71. Savefile is attached below. POKEMON_SAPP_AXPE01.sav

Was trying to copy over the attached spread (see below) onto a Channel Jirachi from the encounter database but received an Encounter Type PID Mismatch error - was there something I overlooked here or could it be some sort of SID correlation (was thinking this could be the case as it seemed to be the only non-constant between different legal Channel Jirachi pk3's I found on here)? Have also attached the relevant Jirachi pk3 file for reference. Appreciate any help! 385 - JIRACHI - 1BA865165E26.pk3

It started today and for some strange reason PkHeX no longer considers the save files made from the emulator to be valid, and I'm unsure of the reason why due to having done 3 actions prior to this happening Note that the sav worked perfectly fine and dandy with mGBA and VBA emus and PkHeX managed to get them fine, but after today, only mGBA can load them while the others fail, and PkHeX gives the error in return. It is not Savestates Steps as accordingly done I've updated the mGBA emulator some time ago to the 7736 ver today, using the Dev ver of the emu that worked fine After that, opened up and started a Jp Emerald with a save creation, later switched to English Emerald with the save For the instance of saving time due to new Uni Semester, used warp codes to get to desert underpass earlier for Ditto, for the Masuda method breeding for later gens. I'll emphasis that I'm at the Elite four for normal eng pokemon and have RNG'ed nearly all 85 caught pokes. Initially didn't wanted a Jp Ditto or a Perfect 6IV one, but once learning about the method, decided to go for it and just to save time as I'm not aware of speed run methods to get there faster, encountered and caught a legit Ditto. Then, saved the game after exiting and wanted to use PkHeX to check the Ditto's legality, whether or not if it is legal after some RNGing the right breeding Ditto, but came to this blockage where it refused to load the Jp Emerald save that it did load fine before. Checked with the English one and it resulted the same issue. Save Files are at 128k or 1 Mb option for mGBA for pokemon emerald saves etc My Conundrum is not knowing what the cause could be, whether its the emulator updating to newer ver, some setting changed that caused the save file issues, was it because of the use of Warp codes or the fact that I used a Jp Save on an Jp E then Eng E and back, and whether or not that caused corruption in the save data or the roms themselves. Earlier backup saves with the Emulator still work fine with PkHeX but am unwilling to potentially cause the same corruption to them Edit: I'll also share that newly created save files and old backed up saves being resaved cause the same issue too

So i playing pokemon brilant diamond and i want to trigger shaymin event using pkhex but it isn't working. i tried to trigger the event manualy and by the fuction called "misc edit".i'm pretty sure i did everything right. Maybe someone have idea. Does anyone know why the event trigger is not working for me ? to avoid unnecessary question , yes i have unlocked national pokedex and I meet all the requirements. BD version ; 1.30

Hi, First of all I would like to thank the work done to gather all the events. Congratulations. I would like to know if it was possible to have the missings wondercards of gen 5 and 6 because they are not available on the topics (compared to gen 1-5) Thanks in advance

Thought I would share, since others may not know how to convert past gen 2 up, that was an obstacle of mine for awhile when learning PKHex. This is the 51273 mail-in Event Mew from Gen 1, converted to Gen 3, with all the data moved up with the best of PKHex's ability. I have set the EVs to amounts perfectly that match the stats from gen 1 SID is nullified at 00000 (Since SID doesnt exist in Gen 2), and the Nature is set to the neutral nature Hardy Set Met location to Colo/XD as (In-Game Trade) Instead of the default "Emerald Littleroot Town" when it was first converted. (I think this is the best setting for PKHex-migrated gen 1&2 Pokemon) Changing IVs would make the mew a whole different mew in my opinion, so I only changed the EVS, so that it has the correct stats that it's supposed to have. This 1998 MARIO MEW is as official as it gets for GEN 3 (Emerald is my favorite game) This Mew is the exact same one given away in 1999 Nintendo Power. (51273) I attached the Images so that way, if you decide to put this mew on a gen 3 cart, you can have some paperwork that distinguishes this mew. 151 - MEW - 1B6500000000.pk3 NOTE: DO NOT ATTEMPT TO SEND THIS MEW TO ANY OTHER GENERATION PAST 5, AS IT WILL GET FLAGGED BY THE POKECHECK DUE TO THE EVS. NOTE: Realized that this mew does not obey, due to the obedience bit in Gen 3 of it not being caught on its native island (Faraway Island). No need to change the met location, as the faraway island mew is very different than the Nintendo Power one. I plan on keeping this in my PC, no intent to battle, just add to the collection. As a fun bonus, ill add a shiny Celebi obtained from GS Ball Event on Crystal in gen 2, I moved it up via this method as well in PKHex (Cleared EVs). SHINY CELEBI FROM CRYSTAL.pk3
