Fun fact: You can extract .iso into a normal folder structure
Not-Fun fact: I only learnt that I had uploaded 11GB on my 60Mb connection and F95 has rules to pack files into zips first
Thanks for sharing.
However without the file otoboku.exe the zip archive seems useless. Can you upload the missing "otoboku.exe" (as single file), too, so that people don't have to re-download everything?
Edit :
I found the exe on another site which is specialized on translated eroges and where the english version was shared in 2012 shortly after release.
I checked the file with my antivirus software and it caused no alarm and after completing setup I had no problems playing the game.
Since other people report otobuko.exe as a trojan (or a false positive), download the exe at your own risk.
Extract the zip to a folder.
Copy the otoboku.exe (see attachment) into the folder.
Use Setup.exe to properly install the game.
Play
Moderator Note: the attached .exe file trips up a number of virus detectors:

DO NOT disable your antivirus software for a game.
At best, you might consider adding otoboku.exe as an allowed exception to your antivirus configuration.
