Eroge! ~H mo Game mo Kaihatsu Zanmai~


The player takes the role of Mochizuki Tomoya, a guy that lives on his own with only a day job at a convenience store keeping him afloat. While he really likes eroge, he can’t draw, isn’t much of a writer or composer, and doesn’t know much about business. Still, his dream is to get a job at an eroge studio in hopes of creating what he loves, eroge.

Tomoya’s luck takes a turn for the better when he sees a help wanted ad for the local studio Flower, and after a meeting with the company president (who to his surprise looks like an elementary school kid), manages to get a job as administrator of the company’s website. Tomoya’s glee at being part of the eroge industry is short-lived, as he soon learns that Flower is on the chopping block due to their first title being a massive failure.

After playing through Flower’s first title, Tomoya realizes that his co-workers don’t know anything about eroge, lacking the insight and understanding needed to make a good game. After some nudging from the president of Flower’s parent company and some soul searching of his own, our protagonist takes it upon himself to save Flower by teaching the four girls on staff the ins and outs of what makes an eroge good. The story thus focuses on Tomoya’s role as a psuedo-consultant while getting to know the four heroines of the story as the player is given an interesting look at the world of eroge development.

  1. seriously:

    use the DA-free game: download

  2. Help!:

    Can anyone help me please. I’m not used to downloads and craks and whatnot. I’ve managed to get to the point where it’s asking me for the activation code and i’ve downloaded the crack along with the rest of the parts of the game using the free one. I can’t seem to find the actual code anywhere in the files. Is there something i’m missing?

  3. tresca:

    Ive downloaded parts 2 3 and 6 several times but every time I extract the game they give me either corrupt headers or vo file issues. Can someone help me please.

  4. JM:

    How can I play this? Every time I try to run it nothing happens, not even an error message. Nothing.
    I have the “pac” folder with: bn, cg, cgsys, ed01, ed02, op, se, sn, st and vo files, the executer(I have placed the Crack), an inst file, an UCOpgDlgRes.dll extension and yscfg.dat file.

    Can somebody help me? I REALLY want to play this game.


    • XiehTie:

      it is just my hypothesis and it could be wrong, but did you make sure that your locale is in japan? because it seems that the game could only run smooth in Japanesse locale. at least it is for me.

      to set your locale (in Windows 7), just go to windows>control panel>change display language>administrative>change system locale. you will need to restart your PC after that, so make sure you close all other programs.

      for other windows/Mac/Linux or whatever OS you are using, please search by your self for I only knows how to change locale in win7. forgive my incompetence.

      and if that does not solve your problem, it is beyond my understanding what else to do.

      lastly, forgive my bad grammar if there is any mistake, because English is not my first language.

  5. Cyber:

    Admin, just thought I’d let you know that this game doesn’t show up in the download section. If someone came here specifically for this game, they might miss it.

  6. Anon2356:

    What do you mean all the girls have the option to cheat? This eroge has NTR…? If so I don’t think I want to play it.


    HOLY F***ING HELL! I had NO IDEA that this was a game! I watched the anime (3 episodes, as far as I know), and it was one of my favorite hentai anime of all time. They were making eroge, which was interesting. I saw this game about a month ago, downloaded it, made sure it ran correctly, and tossed it into my backlog of unfinished eroge. I started playing it, seemed like a pretty normal game, then that intro came on, and I just sat and stared at the screen, thinking “Am I really playing an eroge?!” The intro was INCREDIBLE! Just play the game up to the intro movie, and you’ll know you’re in for one hell of a good time! Play! Play! Play!

  8. Remdur:

    Is it in english ?

  9. justin:

    do you have to clear the game in order to view the scenes again? because im not seeing the option to view the gallery in the title screen

    • Sai:

      after finishing one of the routes, you can find the cg gallery, music gallery and scene gallery under “extra” if i remember correctly

  10. qwerty1104:

    Does anyone have walkthroug???
    can finish the game… T-T

  11. guest:

    is this uncensored?

  12. wondering:

    just wondering, is this translated to english? if not could someone give me a link to the patch

    • Rebo:

      look at the upper left of this site, below the “eroge downLOAD”-Symbol, there’s a short sentence, that should give you a hint.

  13. kitcat:

  14. px:

    Thanks for the game 😉 It looks very comic XD

  15. user:

  16. Loki:

    Help. after finishing nene’s route i went to the extras and only the Cosplay and Naked Appron scenes are on it

  17. Raiden:

    Hello. I downloaded the game and it seems in part 9 of the rar files is a corruption in the cg.ypf file :/ (at least rar is displaying CRC fault everytime for it and I already tried redowloading it)

    I tried to play the game with the corrupted cg.ypf but it crashes always at the same spot. Yeah well anyone know a solution for it? 🙂

  18. Shady:

    Wow this game is godly, a true eroge! it even has the Escape button function!.

    • Gnoll:

      Not much a pro but I realised in recent releases that the visual novels turn more and more into 20h long movies. Stories get better, characters are lovely but if I don’t get at least the feeling to be in controle of things it is not good. Rewrite and Grisaia, both premium titles, are such cases. After it is clear in grisaia who your love interest is there waits only one decision afterwards for you. Until then you have to sit through a 8h long movie! Rewrite the same. Compared to them, older games are much better if it comes to interactivity.

  19. zetsubou:

    Downloaded the game, and no crack in it….. running eroge.exe always asking for activation code…. Help please.

  20. please!:

    where can i find the patch??

  21. romanz:

    Thanks a million for this godly eroge!

  22. Takuto:

    I want to download the game but it requires 2.2GB to download and i cant download it due to max out 200 MB … Can you change the download link

    • kenshin:

      erm use the free one which downloading each several parts as it been using the 1 clikc would need you to upgrade on premium

  23. kiel:

    does this have a patch and a crack?

  24. kame turtle:

    i remember the hentai anime for this eroge, it was pretty good

  25. Yuggoth:

    Ok I’m probably 200% retarded but here goes-DL’d all 12 parts.
    Unzipped 1st no probs.
    Now when I go to unzip 2, it just ask me to replace the folders I just did from 1….and does this for all of the parts.
    How exactly does this work?
    Also I opened the application from 1 and…it booted. Straight to the game.
    WTF is going on?
    I’m very new to this & I apologise for my ignorance but I’ve DL’d things like say Sagara family and they just sequentially asked me to unzip each piece and boom! it worked.

    • admin:

      As long as you don’t rename the archives and put them all in one folder, when you start extracting first one, your software will automatically continue to part two, once it reaches end of part one.

  26. SpikeEye:

    Just be wary… there’s a lot of intense sexual and intense bizarre sexual content in this game. Luckily you can turn most of them off in the options menu. Look through them all before you start a new game so you won’t get any unwelcome surprises.

  27. kenshin:

    How to download crack of it? please help

  28. Skullkid:

    This one is a little too… out there, for my taste 😛

    Still got all the cg and scenes though, moving on.

  29. frost:

    does this game has a gallerie ?

  30. Capostrike:

    Hey, Is in eenglish?

  31. Zag:

    Guys, I don’t know if this counts as a spoiler, but well i will just say it in case


    Be careful guys, there is 1 Yaoi (gay) scene in this game. I had to learn of that fact the hard way x_x

    • Chii:

      In a game with hardcore scat content, yaoi is the thing you warn for? Okay then. Though if you hadn’t “warned” then I wouldn’t have known so I can go DEFINITELY DOWNLOAD THIS so thanks I guess?

  32. Ehuemang:

    The Download from DA-Free Is safe right? First time downloading one of these and don’t wanna get a virus lol.

  33. dears:

    Hey , i got one stupid question how can i extract YPF file?

  40. Rivu:

    I downloaded all the volumes, extracted them, and opened eroge.exe. Everything opened nicely, the sound did work and the .exe file played for like 5 or 6 seconds and then I got this message: YU RIS Debug Info

    What do I make of this and how should I proceed next?

  41. setanta:

    here’s a semi weird question for admin. did you get this game with a patch for the english text which was then applied or was it the one from mangagamer? cause if you had a side patch I was wondering if you could link the english patch as a separate link so we could use it on the remastered version of the game for higher quality.

  42. O_S:

    Man, this was a weird one. I’m all for exploring some fetishes, but they kinda really stretched things out as far as they could in a game that is sorta vanilla at its core (ie not meant to be geared to a specific kink).

    I was also disappointed that in spite of how cavalier it was with each of the character paths leading down the road of sex-crazed debauchery that there’s no harem path. I mean, it practically writes itself. In the middle of the game there are those scenes where everyone’s working in the office and hte AC dies and so everyone works in their underwear. And if you’re on the path of a specific girl, she will usually wear something skimpier than you see otherwise (except Iori, which was a let down). So get to the dead AC scene, have them all in their skimpiest best or strip down completely nude, and then just go at it. It’s not like this game needed a bunch of story justification for them to have a gigantic stress-fuelled orgy.

    That all said, I’m super-thankful they had a button to disable the scat scenes.

  43. Phil:

    download no 3 is crashed…. pease fix it 🙂

  44. unknown:

    keep getting popups everytime using the website to download the parts from which might contain malware and viruses. can you verify if they are malicious popups? as all the ad blocking add ons i find doesnt seem to prevent them from popping up.

  45. mitchy:

    I don’t know if its just me or something, but when I click on any of the free link downloads the web page doesn’t pop up. just goes to yahoo. can someone check this?

  46. Jaren:

    I’m able to get to the download site but the buttons are not responding at all. I’m not able to get it to download.

  47. YuumaTsuyoshi:

    anyone else still missing one CG?

  48. ShadowSteel18:

    Is there any way that “Ero Manga! H mo Manga mo Step-up” will be translated into english. I’ve watched the anime (which was done by the same people as “Eroge! ~H mo Game mo Kaihatsu Zanmai~ the Anime”) and wanted to play the game.

  49. Im new:

    I’m new to this and I don’t have a clue on what to do. Can someone help me?
