HF Patch for Summer in Heat v1.2 (mods up to 2025/02/10)

An unofficial patch for Summer in Heat (夏のサカり) by Miconisomi. It fully translates and uncensors the game, and includes other useful mods.

HF Patch does not contain the game, only mods. You have to buy the game separately. You can buy the game on DLsite or on DMM. Both versions are essentially identical. The v1.0 of this patch was tested on the v1.01_DLsite version of the game but should work on future versions as well.

If you like this game, be sure to check out previous games by Miconisomi. I made patches for those games as well and IO even has a full hand-translation - strongly recommended!

Read before installing

• You must make sure that there are no Japanese characters in the game's folder name (the whole path) or mods may fail to load.

• This patch lets you play the game in both English and Japanese. The uncensor works even when playing in Japanese.

• If you install English translations, you have to start the game through the English launcher. If you use the Japanese launcher then the game will start in Japanese language.

• If you want to skip straight to a specific story scene you can do it through the debug mode. In title screen go to Settings, open Plugin settings on the right, and set any key for the "Open debug menu" setting. Go back to the title screen, click the configured hotkey and go wild. Warning: Back up your save files if you care about your progress!

• HF Patch does not contain the full game, paid expansions or any other pirated content. You have to buy the game and expansions separately.

• This patch works with both DMM and DLsite versions of the game (they are basically identical).

• You can completely disable all mods by running the patch again and unchecking everything. You can run this patch as many times as you want and nothing will break. That being said, if you have issues then try a fresh game install (you can copy the "Save" folder over to keep progress).

• If you want to make your own mods, check https://docs.bepinex.dev and source code of some existing plugins, for example SummerInHeat_Plugins.

• There is no warranty on this patch or on any of the included mods. You are installing this patch at your own risk.

• If you want to run the game under Wine/Proton (Linux, SteamOS, macOS, etc.), read this and this.*

• If the patch asks for a disk or shows a verification error after starting the install - Patch file is corrupted, redownload the patch from a different mirror and/or with a different web browser.

• If you need any help, visit the Koikatsu discord server and ask in the #summer-in-heat channel. Asking there is the fastest way to get help, you can even search it for your issue to see if someone already answered it. There are also mod and card sharing channels on the server!
