Daibanchou -Big Bang Age-


In year 200X, a black hole that would later be called “hellhole” appeared in the center of Japan. Shortly thereafter all contact between Japanese archipelago and the rest of the world got lost.

Giant crystal onyxes named “Crystal B” appeared. Contact with them increased human bodies “B power” and paranormal potential, “special student body” is used to describe those powers young people gained by this change. Emergence of such powers caused panic in the masses and a dark age of violence began.

A few years later a powerful organization appeared, gathering those with the “special student body” to form the nationwide “Students Union” to bring out Japan out of the dark. But the battle was just starting…

    @reynaldo How do you activate it anyway?………

    • Reynaldo says:

      Is like a gameshark for playstation.
      The cheat works when you press that key with the words in Japanese, on the screen that resembles a calculator. But the cheat will be activated only in the next load the game. For example, in a battle, if you turn on immortality, this will only work in the next fight. Start by using the cheat BPs, very easy to activate, and then you will understand how others work …
      It’s hard for me to explain everything in detail, because my English is very bad, but I guarantee it works. If you want to send me an email, I send pictures with details of how to enable cheats.

        I only need the DP cheat because that is the only hard thing to do in this game cause your debt kept filing up in each turn…

        • Reynaldo says:

          Explain where you are having trouble … you could open the SpoilerAL? You managed to load the SSG? You can find the name of the game (大番長) on the list? Please be more specific…

          • kazuya says:

            I don’t know how to activate it like what you press to activate the SpoilerAL…

    I Keep getting a blank Setup utility Error tring to install this plz help

  5. croPath says:

    is it me or does this plot sound a hell of a lot like the one in needless

  6. Say41Plz says:

    Hi there~
    Thanks as always for the hard work.
    My question is if it is neccessary to set the system lenguage or it is possible to run ussing AppLocale.
    Thanks in advance.

  7. shadow00 says:

    having problems with the game, cant install it, keep getting an error thats blank and it just says retry.

  8. VanENTerrier says:

    I’ve tried this n it seems that during the storyline, the characters (heroines) do not talk, i mean, there is no voice..But in the H-scene, there are voices along with the dialogue

    Do they have (release) any full voice patch? Without the voice, the game kinda lack its flair n excitement…

    I mean, theres a difference between visual novels n comics/book novels, without the voice, its like reading normal comic or books with tends to get dull sometimes…

    • darkhero666 says:

      i have the quite same problem
      in the play there’s no bgm and no voice from the character
      asking for some help please

  9. Gizan says:

    I was also having the same problem many others are having with the setup.exe (after clicking to install) in the original game folder popping up with an exclamation mark in a blue circle (alone in the box) and alls it says is “Retry”, which does nothing other than open a different box then re-opens the retry box shortly after, and cancel or close. When I tried what Seithis said, but that whenever I run the System40.exe it just opens the game screen with another pop-up that says DLL [Surface Factory] then some japenese text and after I close that box it is just a black blank screen. Yes my locale is japenese so that has nothing to do with it and yes I tried using applocale and that was also to no avail, if there is any tips/ideas that anyone has that could help me out it would be greatly appreciated, I tried to be as in-depth and informative as possible, but if you need any other info just ask. P.S. I do not know if the .ald or .ain files have any deep significance to their location in the GAMEDATA folder.

  10. OE says:

    Admin do you have any idea why the game can open the datafile.dll with out patch but cant with the patch.

    Without the patch I can play just fine but once I patch it
    it gives me a error box with datafile.dll as its header.

  11. Comnislasher says:

    You need to delete 大番長.ain, 大番長DA.ald and 大番長GA.ald. And then rename ‘å”Ô’·.ain into 大番長.ain, ‘å”Ô’·DA.ald into 大番長DA.ald and ‘å”Ô’·GA.ald to 大番長GA.ald. That work for me.

  12. otabuo says:

    ok i found a dif source for the eng patch and it worked finally >.>

  13. SinSKy says:

    The Patch didn’t work…. what should i do??

  14. BlckDmnd says:

    I seem to be having an issue with the link for part seven. All the other links worked just fine, but for some reason, this link, and this link only, refuses to download.

    With all the other links, I was able to download them at 200KB/sec…with part 7, I just start at 40kb then dwindle downwards until I’m at like 2kb. Furthermore, when I click on the link, I gotta wait like five minutes to even start downloading, whereas the rest pretty much start instantly. Mediafire keeps asking if I want to “repair the link”, but nothing changes no matter how many times I try that. And if, by some miracle, I manage to get the download working for more than five minutes, it just randomly stops altogether and disappears from my download list.

    I’ve tried downloading using both safari and firefox. Firefox had a better time downloading it, but it still just randomly stopped at only 7.4mb.

  15. Bacon says:

    Yea link 7 appears dead, cheers for fix in advanced

  16. Homura says:

    Okay I downloaded from here I downloaded 3 different torrents I have tried everything but I still get a datafile.dll error every single time I open it. I can use it before I apply the patch but after I apply the patch I get that error every single time. I played this game on my laptop about 3 months ago but I got it from a torrent that was pre-patched (but it is dead now) anyway is there anyway to fix it? some people say you need to change the names of the files I did that. I also downloaded the patch from the official website and I applied the text fix patch as well and none of them fixed the problem

  17. Homura says:

    nevermind I reinstalled it and only replaced the 大番長.ain 大番長.ald files and it worked.

  18. Hodor says:

    Seems this isn’t going to work on 64bit systems. I’ve googled and many more have the same problem but no solution. The game freezes after the first battle animations have played. If anyone finds a fix for this, it would be welcomed.

  19. kai says:

    can i still download this or is the download links down

  20. basara says:

    can someone tell me how to fix this problem with the setup, it gets stuck at 99% percent than i get a blank error.

  21. Maniac00 says:

    guys is there any bug in this game cause i cant make any buildings and the debt and loyalty is making it impossible for a game over …. pls pls does any1 have any solution..

  22. Raeft says:

    You can’t make buildings because you haven’t visited Hani Engineering, which becomes available in the National Chapter. visit them for the first time to enable building once you grab Yoko Hama.

    • Maniac00 says:

      thank you for answering i visited them 1st then i went to build the curry resturants….. pls can u tell me what to do ?? Thnx again :D ..

  23. Negi says:

    ummmmm so this game doesn’t have a “FULL” voice patch?

  24. tang says:

    So when I try to play this on my 32 bit system it also freezes during combat when I attack, can anyone help?

  25. Majinkhuna says:

    Has this been uncensored or not?

  26. pure says:

    how can u play it in english language

  27. Rckstan says:

    Hey guys, can anybody tell me how to defeat/capture Mitamazuka Youki? i just cant, i have watched the events in shinjuku, and when i attack her, she just espaces with 1 hp, what i need to do?

    • thelegaard says:

      you need to capture the provins first, then you can capture her, if you want to hire her you need to get the guy called touma kentarou or some such, the owner of the rice cracker store. to get him visit there 3 times, then he will join you. when he has joined you talk to him twice then you can hire youki.

      also you cant hire asakura yuma while youki is in your prison, or she will escape

      • yussen says:

        i got youki…^o^…all u have to do is use characters with high capture rate status (ie franchine)..just capture her then bring touma to her ^__^

  28. Banana-man says:

    when i want to download it after mounting it with Daemon its,a small box appeared with weird words…and i cant install it properly..somehow
    someone please tell what can i do?Admin?

  29. kitsune500 says:

    Has anyone got this to work on Windows 7? I get an error message as soon as the game starts and it will let me watch the alicesoft opening but, after that it goes to a black screen and nothing happens regardless if I add the patch or not. So has anyone had the same problem as me and fixed it?

    • another thing says:

      i have got it work on win7.
      all you had to do is to manually replace the jpn file (.ain,DA.ald,GA.ald) with the eng patch file and you have to rename the eng patch file using the jpn file`s name.

  30. Hammer says:

    Can’t get the full screen mode past 640×480. Anyone had the same problem or know of a fix?

  31. pure says:

    then plz can anyone rename the eng patch file using the jpn file`s name cause i dont know how to do it

  32. Naomihuntr says:

    can anyone tell me where the data save files are located, & could i copy it to another PC?

  33. FFTHEWINNER says:

    This is a GREAT game. it has a TON of content(i played it for tens of hours and saw less than 30% of its content),a very good plot,good sex,great gameplay. the only problem is that it is VERY hard.i thought many times that i was done for >_>.

  34. Ijen says:

    I really liked this game! awesome! i cleared the normal and the hard mode!but of course not in a satisfying way!i got 50% cg’s only!the game is quite hard!if you don’t use your brain you will die!i got at least almost all the characters!

  35. Eulogy says:

    I’m still having trouble playing the game, I’ve installed / changed the names of the ain and ald files with the ones from the english patch but every time I try to launch it only has a black screen. I’m really stuck on how to fix this :(

  36. Eulogy says:

    redownloaded and followed the steps that everybody suggested and it worked this time. Took awhile but I have to say from what I’ve played so far it was worth it. Thanks everybody :)

  37. ALEX says:

    I am having trouble with the game, it comes up with an error in japanese with DataFile.dll in the title bar. I have done what was suggested above with no effect.

  38. John Stuart Boustead says:

    Hi how do i cheat for daibanchou big bang age

  39. AT says:

    I have a problem, cleared characters dont appear in char clear menu. Does anyone have same problem or knows how to fix this?

  40. Livez Einzweil says:

    interesting game but no voice acting…. well I just started playing it so I don’t really know but the game and the patch works just rename them.
    one question though, how to save in this game?

  41. kakalxlax says:

    could you change the server so i can download it using jdownloader?

  42. Dylan says:

    After downloading all the files when I go to Extract them it keeps saying that a part of the archive is missing. Pls help

    • -M- says:

      If you downloaded via DA-Free make sure part 1 to part 7 size is similar.

      • Dylan says:

        sizes are similar and has been happening with other rar files I downloaded.

        • -M- says:

          You can try to download the “problematic” archive once again. I have a problem too, but different from yours. After I copy and paste the English Patch, appears message box contains DataFile.dll with some Japanese text then the girl from Alice Soft and blank screen and nothing happens. But without the English Patch, after the girl from Alice Soft appear, the game run smoothly, in Japanese of course >.< Have to try to reinstall again, maybe.

  43. noire1266 says:

    that’s because your rar/archiver doesn’t translate the files in the original context/text instead it uses gibberish. notice the original files in jap?ones ending GA.ald, DA.ald and one with 大番長.ain? while the english patch zip comes with ‘å”Ô’·GA.ald, ‘å”Ô’·DA.ald and ‘å”Ô’·.ain. all you have to do is rename those gibberish english patch file same as those corresponding orginal files and replace. GA.ald/DA.ald and .ain

  44. px says:

    For thouse having problems with the “Datafile.dll”:

    You just need to do this and the problem is solved XD. Thanks to Comnislasher ;)

    You need to delete 大番長.ain, 大番長DA.ald and 大番長GA.ald. And then rename ‘å”Ô’·.ain into 大番長.ain, ‘å”Ô’·DA.ald into 大番長DA.ald and ‘å”Ô’·GA.ald to 大番長GA.ald. That work for me.

  45. Katamichi Hazuno says:

    OK, i found a way. delete and rename only the .ain and DA.ald ONLY. don’t copy the GA one :D try it. (cause when i copy the GA, i can’t start it.)

  46. Katamichi Hazuno says:

    The GA.ald is broken admin-sama. could you reupload that one ?

  47. flowright says:

    When i run the game, menus are in english, its ok. But all dialogues (and names) are in japanese.

    In patch file, I found :

    DLL folder with


    and the readme one

    i think im missing files like ‘å”Ô’·.ain, ‘å”Ô’·DA.ald, can someone help me? plz

  48. Mr. Edge says:

    For those who keep getting a blank error message during install, you need to install the game with Japanese locale on.

    If you’re using AppLocale like I am, go into the CD-ROM’s files and “Run with Japanese locale as administrator” (AppLocale can’t run the file without admin).

  49. Dragon King says:

    Can some one help, I used to be able to play it but now it keeps freezing during combat, anybody know how to fix it?
