How to download and install the patch
Text guide
Download the patch to any directory other than the game directory.
Start the included .exe file. A UAC prompt should appear. When you click Yes the patch installer will start.
Follow instructions in the installation wizard (for most users all you need to do is keep pressing Next).
If the installation location was not automatically detected, you will have to show the patch where your game is installed. The game folder should have a "GameData" folder inside of it. Make sure that the game folder does not have any Japanese characters in its name (best to place it in a folder like "D:\Games\SiH").
If the patch asks you to insert a disc, the patch file is corrupted. Redownload the patch and try again.
After the patch installation finishes you can remove the downloaded patch files. That being said, I suggest keeping them in case your game breaks for any reason and you need to install the patch again to fix it.
What to do in case of download issues
If the download is very slow or fails to start, try a different download link and/or a different web browser. If all links are slow test your connection speed. If you have a VPN try changing the server or turning it off. If all fails you might have better luck with the torrent download.
If you see any messages about corrupted files or if the installer asks you for another disc you'll have to re-download the patch. Try using a different download source and/or a different web browser.
Make sure that your antivirus is not flagging and removing the .exe file.
What to do in case of installation issues
If you get a "This patch is inside of the game directory", "Path too long" error, move the patch files to a folder like "D:\HFP\" and try again.
If you get a "Different game is detected" error, make sure this is the correct patch for your game. SiS in the title means that this patch is for SummerInHeat (doesn't work on other games like SamabakeScramble).
If after installing the patch you have issues running the game, restart your PC and try to install the patch again with default settings. Try moving the game to a simple folder like "D:\Games\SiH".
If your antivirus is flagging the .exe file make sure that you've downloaded the patch by following links in this post. If you are sure the download came from the right place, it's most likely a false positive (it's a common issue with non-signed application installers).

In some cases you can make them go brain empty but not really emotionless, it'd need a mod.

Hi, I want to ask. It's possible to make the girl to emotionless while having sex? Or do you need mod to do it?
