/HW-1C@C8B8:advhd.exe seems to work.
Credits to an user on hongfire's agth request thread though originally it was for 乙女が結ぶ月夜の煌めき so it might break down the line.
It's one of those "Japan only" games with hard checks so just changing your local/UI/formats won't fool it.
Either run it on a fully japanese VM or use Locale Emulator.
Turns out it was a local issue even though my locale was already set to japanese... I guess this is one of those games who also want the rest of the UI, formats, etc. to be set to japanese as well.
The game keeps giving lua script errors every time a H scene triggers during the fights, seems like either the upload is corrupted, my PC has some problems or we need version 1.1
Looks like only the installation folder was uploaded but the game won't start without the registry entries from the installer ?
Try installing the trial version and mix the files around, it could work.
I don't know if I've missed something but the game didn't have a crack and alpharomdie didn't work, probably because the game is too old.
Using AlphaROM 2.1~3.1汎用 rev4.rar on the reg.exe file did the trick though.
I fail to see what's the point in adding gameplay, if you're going to screw up balance so bad you give the player overpowered equipment to get throught it like it's a nuisance.
