Homebrew Custom game icons tutorial and sharing hub

What is sys-tweak

It's a collection of "patches" that intercept .nca info from games, and override them. In simple words it allows override icon and name displayed in home menu. You can have custom icons and title names.

Example:

It's mainly targeted to user that don't want to use .nsp to create forwarders or simply mod the icons/names for official games, it doesn't involve any piracy method and is ban safe.

Installing sys-tweak

Always refer to the official github site sys-tweak, click on the latest build by selecting the first workflow link under Actions tab, download sys-tweak.nsp (you need to be logged to your Github account) copy and rename it to:

atmosphere/contents/00FF747765616BFF/exefs.nsp

Create a flags folder with an empty boot2.flag file in:

atmosphere/contents/00FF747765616BFF/flags/boot2.flag

Optionally create a toolbox.json in:

atmosphere/contents/00FF747765616BFF/toolbox.json

To enable/disable sys-tweak from sysmodules overlay, toolbox.json should be:

{
  "name": "sys-tweak",
  "tid": "00FF747765616BFF",
  "requires_reboot": true
}

Creating custom icons

Once sys-tweak is set, reload your CFW. Now you can customize your game icons by copy a 256x256 jpg image no bigger than 128K or you will get a queston mark instead.
The icon only accept jpg format not interlaced, copy it to your title folder ID, for example Resident Evil 4:

atmosphere/contents/010099A00BC1E000/icon.jpg

Editing game names

You also can change the title name, author and version, just place a config.ini file in the same folder as your icon.jpg, the file structure is:

[override_nacp]
name=my custom title name game
author=someone
display_version=X.X.X

Note: If no config.ini is present it defaults to original title.

Thanks to @p-sam for creating sys-tweak, and up-side-down Claude von Riegan that motivated me to change incon in FE: Three Houses :rofl2:
