Hello, someone know why I can't play when i install the R18 patch ? I juste have a grey screen with the menu in red when i pass on with my mouse, and when I click where is the start I just have a black screen without sounds.
Edit : solve, I delete the game and re install in another folder, and apply the R18 in another folder (separate).
Had the same issue and, after some tinkering, your solution worked for me too. I'm going to clarify this for anyone else who comes after, since it's one of the strangest VN installs I've done. The fix is:
Install the game into a folder.
Launch the adult patch exe.
Install that into a different, empty folder.
Leave both folders as they are. You, bizarrely,
do not want to copy and overwrite the patch files to your install folder, as it corrupts something.
Boot the game up, and you'll see the title has changed from "Trinoline (all ages)" to "Trinoline (english)." This is the confirmation that the patch worked. It must still read the files even in the other folder.
