Anon from 4chan said this: ''I took a very brief look at it. Seems like it uses CypherGuard DRM (a few minutes of investigation lead me to some threads on /g/ about breaking it but they don't get too far). The executable doesn't appear to be protected, seems more like the data file is. You can trick the trial version's .exe into running with the full game's data by creating a folder called "setting" with an empty file called "taiken.txt" inside it, but that just causes it to immediately close like the regular .exe does (inspecting with a debugger shows that it's crashing, likely because the data file is encrypted). ''
Also
''You could go to e-hentai and message genl to crack it, but he'd need the account details of whoever purchased it in order to break the encryption. So for the game to get cracked, somebody will need to buy it again (unless we can contact whoever uploaded it to SVScomics).''
And sadly...
''If anything the DRM this game uses encourages piracy. If you read the "activation instructions", there's this lovely piece of text:
>If you purchase a product which requires user authentication as a guest, the file(s) may no longer be viewable if you perform the following:
>
> Change/replace your operating system.
> Reformat the hard disk drive on which Windows is installed.
> Change/Replace your hard disk.
>
>If such is the case, if you wish to view the product again you will need to repurchase it. ''
So this DRM is bs.
