NDS firmware editing menggunakan Hex Editor


ini dia tutorial buat yang pengen mengubah bahasa (Language) dump firmware secara permanen (buat yang dapat firmware dari internet dan bahasa ngga sesuai ama preferensi).sebelumnya cerita dulu ^_^ kenapa mengubah bahasa, well, kita di indo jelas ngga ada bahasanya sih, tapi kan lebih nyaman make bahasa yang kita inginkan di firmware (dimaenin via No$gba) daripada bahasa ngga jelas ^_^ *ku sendiri awalnya dapat dump firmware dari rekan di forum, yang originalnya dari NDS menggunakan setting bahasa perancis, gila aja. beberapa game terpengaruh ama firmware loh (kalo dimaenin make firmware, kalo via emulator) macam picross, meski aku punya versi US, begitu firmware pake perancis, wuih, langsung deh ingame jadi perancis TT_TT
bisa aja dirubah waktu menu diplay lewat emulator, tapi berhubung dump, save ini ga bisa disimpan permanen, jadi tiap mau maen mesti rubah dulu, trus reset, baru klik gamenya buat ngeplay game TT_TT

nah buat kamu2 yang ngga mau selalu repot gitu kalo maen menggunakan bios dan firmware asli, nih solusinya, meski rada susah diawal, tapi mempermudah kalo udah selesai ^_^

  1. yang pasti harus punya firmware.bin (baca post NDS bios and firmware)
  2. Buka website : On-line CRC calculation and free library
  3. buka firmware.bin menggunakan hex editor pilihan kamu (aku sih make winhex)
  4. browse ke posisi 0x03FE64
  5. ganti nilai 0x02 (french nih) ke bahasa pilihan kamu(0x00 untuk Japanese, 0x01 untuk English, 0x02 untuk French, 0x03 untuk German, 0x04 untuk Italian, 0x05 untuk Spanish)
  6. ke posisi 0x03FF64 dan lakukan hal yang sama dengan nilainya
  7. sekarang salin 70 byte data dari posisi 0x03FE00 (0x03FE00-0x03FE6F) ke website dan generate crc, yang perlu diingat/dilihat hanya CRC-16 (Modbus).sebagai contoh nilai 0x02yang dirubah ke 0x03, akan memiliki nilai crc-16 0xB8A7
  8. pergi ke posisi 0x03FE72-0x03FE73 dan ganti nilai 0x5A7B dengan nilai yang baru, ingat untuk membalik nilai yang baru, nilai 0xB8A7 diisikan menjadi 0xA7B8.
  9. sekarang salin 70 byte data dari posisi 0x03FF00 (0x03FF00-0x03FF6F) ke website dan generate crc, yang perlu diingat/dilihat hanya CRC-16 (Modbus). sebagai contoh, nilai 0x02 yang dirubah menjadi 0x03, bernilai 0xEB64
  10. pergi ke posisi 0x03FF72-0x03FF73 dan ganti nilai 0x9928 dengan nilai yang baru, ingat untuk membalik nilai yang baru, nilai 0xEB64 diisikan menjadi 0x64EB.
  11. save file

Catatan : kamu juga bisa mengubah nama, tanggal lahir dan setting laen, semua setting ada di area 0x03FE00-0x03FE6F dan 0x03FF00-0x03FF6F. detailnya liat bawah, tapi jangan lupa setelah mengubah nilai, selalu generate crc-16 dan replace nilainya.

English Translation :

  1. You certainly must have the firmware.bin file (baca post NDS bios and firmware)
  2. Open the website : On-line CRC calculation and free library
  3. Open firmware.bin using any hex editor of your choice (i personally recommend winhex)
  4. browse to adress 0x03FE64
  5. change 0x02 (if you happen to find bios with teh name alexandre and french language on it) to the language code of your choice (0x00 for Japanese, 0x01 for English, 0x02 for French, 0x03 for German, 0x04 for Italian, 0x05 for Spanish)
  6. go to adress 0x03FF64 and do the same wthing with the value
  7. now copy the first 70 byte data starting from adress 0x03FE00 (0x03FE00-0x03FE6F) top the website supplied above and generate crc, one thing need to be note is just the CRC-16 (Modbus). as an example 0x02 that has been changed into 0x03, would have a crc-16 value of 0xB8A7
  8. go to 0x03FE72-0x03FE73 and change 0x5A7B with the new value, IMPORTANT : reverse the value, for example 0xB8A7 become an entry of 0xA7B8.
  9. now copy the first 70 byte data starting from adress 0x03FF00 (0x03FF00-0x03FF6F) ke website dan generate crc, yang perlu diingat/dilihat hanya CRC-16 (Modbus). top the website supplied above and generate crc, one thing need to be note is just the CRC-16 (Modbus). as an example 0x02 that has been changed into 0x03, would have a crc-16 value of 0xEB64
  10. go to 0x03FF72-0x03FF73 and change 0x9928 with the new value, IMPORTANT : reverse the value, for example 0xEB64 become an entry of 0x64EB.
  11. save file

Catatan : you can also change the name, birth, and any other setting in the address range of 0x03FE00-0x03FE6F and 0x03FF00-0x03FF6F. For detail see below, but don’t forget to generate a new crc and replace teh crc value (see step 7-10)

by the way, if you got bios from my other post here, it’s already in english so no need to change the language, nstead you can try to change the name or other detail ^_^

  1. english translation..
    ehm.. okay, on my way.
    i’ll translate the main steps, in few hours ^_^
    *still got something on my hand, so it’ll have to wait for a while. so check up on it later
    well, your welcome ^_^
    EDIT : translation done ^_^

  2. well, the one actually can be edit is the firmware not bios ^_^
    check the adress 03FE06 and 03FF06
    you should get some value like this (in ASCII character) if you use my firmware => S.e.t.y.a or A.l.e.x.a.n.d.r.e if got it from other source.
    just change t into your name such as A.z.9.0 chngae the following char with dot (that would be 00 in hex, f you edit the hex not the ascii)
    after that don’t forget to change the valuein 03FE1A and 03FF1A with the value represent the number of char use for your name (in the case of Az90 would be 4, dot isn’t count since it would be blank value)
    and then, do the steps from 7-11 to change the crc code, without it, your firmware would fail

    if you still have some problem, you can write teh detail about yur name and other data you wanna change (such as bith day, language or other) and i’ll try to change it for you in my spare time

  3. That’s good. I hope you can help me for this. My brother want to get his name for No$GBA, so they get me for help. I can’t do that for him. If you please, can you make it one for him? Here are the details:

  6. @rascal : hex :)
    @dle333 : thankz :)
    @phozon and mewtwo : i’ll be going out of town for a few days, so kinda busy lately, i’ll try to do yours tomorrow before leaving if i got some time, if not check it again in a week.

  7. why dont you try to do it yourself? it’s really easy with this tutorial… I’m not an expert and I’ve never hexed anything before, but it was easier than I expected. just follow the instructions and you cannot fail!

  8. @mewtwo your welcome
    @8dmn be sure to copy all block starting from adress point 3Fx00 to 3Fx6F (where x is E or F), that would give you 70 bytes of data.
    @dle333 yup, it wasn’t that hard ^_^ and congrats to be able to edit on your own :)

  9. Hi setya,i found this very informative but i’m not that good in editing..so can you please make a bin for me?

    maybe you wanna help me with this one dle333 ???

  11. @dle, lol, yeah that’s right ^_^
    @dominion, if you follow it exactly, it wouldn’t fail ^_^ try again.
    really pay attention on step 8 to 10

  12. yes, i reversed the values, and it didn’t work

    as a test, i also Checked the CRC of the original 70 bytes, and it was correct.

    After changing the 70bytes, checking the CRC again, and putting that in, i get the nintendo DS bootscreen, and it tells me i have to input my nickname, date/time etc.

  13. can the english steps be clarified further, the sooner i can get this worked out, the sooner a Firmware Editor can be moade.

  14. can the english steps be clarified further, the sooner i can get this worked out, the sooner a Firmware Editor can be made.

  15. im having with the birthday its 29 when i change the values the ASCII text change to ) so the bios doesnt work, can you tell me how to work this out

  16. for birthday, change the value in hex column, with another hex value. instead of 29, use 1D.
    teh same goes for any other value, use hex value.
    for text, it’s different, simply change the text using ACSII char, in text column

  17. mau tanya nih. salam kenal dari saya. setya mengenai 70 byte data yang disalin itu. apa ditulis semua dari 0x03FE00 sampai 0x03FE6F atau digimanain? saya coba ke CRC on-line calculator kan ada ASCII or HEX mana yang dipilih dan berapa nilai yang mau dimasukan. klo pake contoh dari firmware stya. terima kasih banyak.

  18. Yes! Thank you! at last I managed to edit the firmware, I had problems with the birthday and favorite color but I managed to solve them by reading what you said about the hex values for the birthday number ^^

  19. Hi setya could you help me with the firmware too cos i really suck at doing it:

  22. someone currently making an editor for firmware.bin (so no direct hex editing would be needed anymore), let’s just wait for that co finish ^_^
    my jobs are killing me at the moment, rarely have spare time lately ( and i use most of them to rest now)

  23. Now isn’t that funny? now that Setya, me and the few others who managed to get around to edit the firmware, some starts to develop an editor, then again it will be useful when we get bored of our current settings and wish to change it without have to go again all the way on the hex editing XD

  24. yup got that right ^_^
    a guy named mudlord currently doing it, so for others who can’t (afraid) to mess arround with hex editor could simply click a few buttons to make it all happen :)
    for me, i like coding, hex, binary, but then again, if there’s something easier, why not ^_^
    hopefully mudlord get it done soon ^_^

  25. nice progress ^_^
    let me know when you’re finish it already.
    and with your permission, if allowed, i wanna post/host it on this blog (certainly, credit goes to you) ^_^

  26. @Bouba1: Yeah, I will do it when I get a spare moment.
    @setya5785: Another update. I worked out exactly how to do the CRC16 check on the bytes when finalising the file. Seems the answer was in front of me the whole time (fseek(), and fread()) =p. So, once I implement these checks, development should be much easier. I hit into a problem though. Because of the strings use UTF-16, my patcher will most likely not work on Windows 2000, XP, or Vista, because the program uses Unicode file handling routines to write those strings.

    Other than that, things are smooth sailing.

  27. nice progress ^_^
    well it’s not such a bad thing to only work in microsoft family since that the most likely used OS, and since the one really can use this firmware is nocash (which is only available on windows and dos) so not a problem, i guess ^_^

    let’s just hope this one also work nicely via wine (linux) or darwine (mac os) ;)

    wish you the best for your next progress ^_^

  28. Got another update, string writing now should work on Windows 98/95/whatever. I worked out a simple hack to add 0x20 after each letter is written, so that entering letters works flawlessly, as Unicode is just a extension on ASCII. Although, with this method, special character input (like kanji) won’t work.

    But at least its a start.

    I tried dozen of times to hex my firmeware and no luke.
    The only thing I want is to Set it to ” French “.
    Could you, please, when you got time to hex it for me ?

    Thanks a lot for all your help and thanks a lot for all your hardwork too.

  33. Hi!
    Great Tutorial! Thanks a lot!

    But i have a little problem… I think I’ve done everything correct but when i start no$gba i hava to configure my “ds”. But it can’t save that settings. If i set the entry-point to “Start Cartrigde directly” everything works fine!

    Can you help me please?

    Here’s my current binary with the settings i want:

    Name: Robert
    Birthday: 22.04.
    Language: German


  34. since the firmware are flash memory dump, it can’t save those value to firmware bin,.
    i’ll try to work on it later when i have some free time.

  35. Wow, I’m a complete idiot. I had tried to do this before you translated into english and wasn’t quite clear on the copying of the 70 byte hex values. I was adding them together, not putting them all in, as is, in order into the crc checker. Once I realized what I was doing wrong and did it how you’re supposed to, it worked out fine. Thanks for the great guide!

  36. yeah hopefully you didnt forget about me setya:

  39. no need to look for RAM address, as that would only apply if you monitor real DS ram :)
    only look for the offset on hex editor, i’ll get to it in week end, maybe, kinda busy on school days :)

  40. All these edited firmware can be downloaded from http://www.mediafire.com/?0iproedvtt7

    note : i put them all in one archive to make it easier for me to upload, so download the archive (rar file) and get your edited firmware

    Good luck for the next~

  42. your welcome ^_^
    keep checking my blog, i’ll keep writing about this DS emulation if i find something new ;)

    “You should become an informatician! ;)”
    in the matter of fact, i am actually one ^_^

    thankz for your support ;)

  43. HEy, can u tell more specificly how to change using winhex….
    i quite lost. when i open the firmware, i didn’t find 0×03FE64

    hey what give the idea to do like this??
    Good luck!~

  44. @magnum…
    that’s the file offset (on left pane just beside hex code, conside rthis as line number to make it simple, in default, at top, you’ll also get a number from 0-9 and then A to F. so to get to 0x03fe64, read the ‘line number’ on the left and look for 0003fe64 (don’t mind how many zero are hey in front of those number), after you locate this one, see the hex under row 4, that’s 0x03fe64 is ;)
    if you only get numbers (without any letter on ofset pane) just click it to see ofset in hex mode (not desimal mode)

    good luck to you to ^_^

    ehm.. the idea struck when i played using real NDS firmware, i don’t have my own DS, so i got one on the net, and apparently, the one ‘lurking’ on the net is the spanish (if not mistaken) firmware (already set in spanish) owned by alexandre. so i look arround for some detail on the firmware and got it spec, and then do some editing so i can have an english version of my own ;) so, i wrote what i did here so if anyone else wanna do the same thing, they can do it as easy as following this tutorial :)

  45. hey, can you also make me a firmware

    and hey, you are quite ‘rajin’….

  47. @magnum, if you change firmware setting on real DS, and them dump your own firmware, the setting will remain the same with your setting ;)
    @andes… be patient, it may take a while till i get on it ^_^

  50. @el dred, haven’t tried to check on mudlord’s app.
    beside teh fact that i’m kinda occupied with other thing that demand higher priority, i’m a bit inexperience in C++, i’m more on java most of my time ^_^

    @magnum… see answer above ;)

  51. i see…scanning his codes,i guess some of the address pinpointing is off…cant pinpoint where it is in the code though…

  52. in my case, i can’t compile his code (i’m using VS2008). need to adjust some of the code.
    but anyway, i’m still happy with my hex editor :) so i don;t really want to botherusing any tool, not really gonna edit my firmware too often anyway, in fact never, well unless there’s someone want their firmware edited here ^_^

  53. i see,i guess that’s where you’ll have to manually include a library in the project…it’s not included in the project file so when compiling,it gets an error since it is looking for it.

  54. Can you please upload a firmware with these edits?

    How about programming a GUI where you enter variables into their respective fields so everyone can customize their own firmware? Sorry if this is harder than I thought, it is just a suggestion.

    You could also just put a John Doe firmware, with 01/01/88 bday, grey and english.. Not that your info is bad, but it is your personal info, not a general info… I think.

    Or you could accept my request, this is also excellent!

    Until then, may I ask few questions:
    where am I supposed to find
    FW Offset: 0×03Fx06
    or RAM address: 0×027FFC86 in the winhex?
    even tho I might get one from you, I’d like to learn how to use it so I don’t have to request you again when I need to change some.

  64. gimana cara buka tuh scrip tiap game2 nds?
    biar bisa blajar bahasa programnya gitu..bales ke emailku yach..
    penting nih soalnya…

  65. @Naman… wait till the end of weekend
    @captain-J, thankz for being patient till weekend :)
    about that address
    ds firmware write data on 2 place between 0x03FE[x][x] and another mirror on 0x03FF[x][x]
    so when i say 0x03f[x]06, look at 0x03FE06 and 0x03FF06
    (or simply at address 03FE06 and 03FF06 since hex app rarely include 0x in front ofset)
    ram address refer to nds ram address, so nothing to be worried for ;) just look at hex offset of your firmware file.

    @arezz tiap rom beda2, ehm.. mungkin kamu bisa baca halaman patch tales of innocence, udah ada yang eprnah nanya dan aku udah jawab di komen2 terakhir tapi itu berhubungan dengan patch.hack translasi aja.
    kalo mau belajar pemrograman game/nds harus belajar lewat cara laen, bisa kamu dissaebler kode game ke bahasa assembly tapi kamu harus belajar assembly dulu ::( khususnay untuk ARM.
    coba search devkitpro dan PaLib, tuh digunakan untk pengembangan homebrew aplikasi DS, ga ada hubungan ama post diatas ini loh :)

  66. I see…. I think I understood about reading the hex value so far. Thanks for the response.
    But I don’t still get the part 7.
    do you like mean drag the whole 00s 4As and stuffs between the offset values you mentioned to copy and paste on the text box of the website you told us?
    and I don’t get part 8 neither, because, to me, only thing I could change in the hex programs is bunch of 00s or AAs some two alphanumerical values but nothing like 0×5A7B to reverse it.
    I only see things like on the screen:
    Offset | twin alphanumerical values | text |
    0003FE00 | 05 00 00 07 05 00 43 00 61 00 70 00 74 00 61 00 | . . . . . . C . a . p . t . a . |
    something like that.
    Hopefully that made sense – if it doesn’t, I’ll just shut up and wait till weekend :S

  67. @caoatin, yes drag and copy hex value and paste on that site (don’t forget to specify as hex, not ascii) and then generate crc.
    you’ll get some crc, teh one you need gonna be crc-16 modbus, you’ll get 4 char right let’s say AB CD
    when you put it back to your file in hex, you must flip those value before writing it down, so AB CD gbecome CD AB, so you change your firmware fiel at the offset i mention to become CD AB (not AB CD as you get from that site).

    well, like you said, if you don;t get it, wait till weekend :)

  68. setya,

  72. I’m the one who provided and I think that mullord can get up some hint from it to complete his editor.
    It’s not completed and only changes name, colour, language and birthdate but no other option like alignment of GBA screen in Touch or main one.
    Neither an option for the welcome message.

    terima kasih

  101. I don’t understand your Steps. Could you .. uh … maybe be a little more specific on how to perform those tasks ? ..

    • if you’re confuse, i assume you don’t have experience using hex editor.
      it’s better that you don’t mess around then :)

      beside you don’t need bios/firmware anymore, and any bios/firmware would work the same. just use any bios/firmware if yoiu want to use it on your no$gba

  102. wew baru tau juga gw ada beginian .. kak setya buatin kasi saya bisa ? please kak .. sama2 org indo sekali aja merepotin gpp ya hahaha
    nama joseph , color nya blue , tgl lahir 27 juli .. pesan welcome itu aja hehehe .. boleh dong kak

    • ikutin aja guide di post :) atau cari aplikasi yang udah bisa langsung, keknay udah ada beberapa yang bisa edit tanpa perlu pake hex editor.
      bios/firmware asli juga ga dibutuhkan lagi untuk emulator

  103. ah ga ngerti gua hahaha .. gpp deh :)
    saya masih tergolong baru dalam bermain game ds di emu .. mnrt kak setya lebi bagus demusme atau nosgba ya .. klo saya liat sih demusme lebih enak digunakan soalny g pake extract tapi koq lambat banget ya klo mainin game 3d .. klo nosgba yg kurang hanya ga bisa di save slot2 nya itu kak .. ad masukan ga ?

    • :)
      lebih bagus desmume, sampe sekarang masih diupdate dan dikembangkan (downlaod svn build dari emucr), jadi untuk maen, lebih baek. tapi cenderung sedikti lebih berat daripada no$gba. jadi kalo cpu kuat, mending desmume, kalo ngga bisa coba no$gba (kalo game bersnagkutan ga masalah).

      no$gba emang ga ada save state untuk game NDS, jadi emang harus save normal aja. tapi aku rasa juag enakan gitu.

      kalo mo pake no$gba, tambahin juga no$zoomer. addon yang juga nambahin beberapa fix untuk game2 tertentu

  104. ho gitu toh .. makasih ya pencerahannya kak setya .. dapat info bagus gua .. tapi telat banget gua taunya .. org2 pada nanya dari ta0n 2008 gua 2011 baru tau wakakaka .. yg ga ngerti masi soal ganti nama itu , g dpt softwarenya .. buatin lah kak .. pleaseee :p

  105. kang ane mudeng nih kagak ngerti sama sekali, bisa tolong dibuatin aja gk firmwarenya ? kalo bisa makasih

  106. I hope it isn’t to late, but I really want to learn how to manage this. I’m already lost, hardly on step 4. What do I browse? Do I browse through my WinHex, because I can’t find anything on that using control + f. Or, do I browse on the website given? I add the numbers & letters, calculate the CRC, but then what? I hope it isn’t out of the blue, but thank you in advance, regardless.

    • I realize I need to browse my WinHex, reading future steps, but when I search for 0x03FE64 it’s drawing a blank. I have no experience with hex editors, so again I apologize. I would appreciate some effort in help though explaining this, please. ><

      • that’s the address / data offset (not the content, so don’t use search function), just browse your file content, you’ll see “offset” on the left side of your hex content.

        btw, you could try googling nds bios editor, iirc, there are few editor available.

  107. By the way, I had no idea there was editing software already made (lol). Doing it manually was a little confusing at first. I found the offset and all, and managed to figure out which each set of numbers represented. After a while of messing with it and playing around I got what I wanted.

    Thank you so much, this is so nifty. ^^

    • your welcome :)

      there’s a tool for viewing/editing nds rom such as tile, text, etc. quite helpful for creating translation (sorry, can’t recall the name). it also include an option to edit ds firmware. and probbaly some other standalone app.

  108. That’s good. I hope you can help me for this. My brother want to get his name for No$GBA / DeSmuME , so they get me for help. I can’t do that for him. If you please, can you make it one for him? Here are the details:

  111. Hi! I could have sworn I’ve been to your blog before but after browsing through many of the posts I realized it’s new to me. Nonetheless, I’m definitely pleased I stumbled upon it and I’ll be book-marking it and checking back regularly!

  112. Pretty great post. I simply stumbled upon your blog and wished to say that I have really loved browsing your blog posts. In any case I will be subscribing in your feed and I hope you write again very soon!

  113. Thanks for the tutorial, it is quite clear and easy to follow
    I had never used a hex editor before so when I achieved change my firmware I felt like a super hacker ;)
