Requirements

• Original copy of the game.
• BepInEx (bundled in the release).

Installation (Windows)

• Download the Sui's Hack and extract it to game directory.
• Launch the game.
• Press F11 to open configuration GUI or close the game and edit "SuisHack.cfg" inside the BepInEx/config folder.

Installation (SteamDeck)

• Switch to desktop mode.
• Download Sui's Hack and extract it.
• Open Steam (in desktop mode) and find Deadly Premonition 2 on the list of games in your library.
• Right click on it and select Properties.
• Go to Installed files tab and select Browse... - this will open a new Dolphin file explorer window.
• Copy extracted files to that directory.
• Now return to Deadly Premonition 2's property window in Steam and go to General tab.
• Under launch options paste in the following WINEDLLOVERRIDES="winhttp.dll=n,b" %command%
• Launch the game.

Bugs

• Final boss doesn't seem to display controller prompts correctly.
• Epilepsy warning! TAA causes issues with shader of phantoms in the otherworld, so if you are prone to suffering epileptic seizures - use SMAA instead.
• Occasionally the protagonist may fall through the terrain when using interpolation. Sorry :(

Notes

• Replacing gamepad prompts requires generally requires modifying Steam Input profile, you generally want:
  • Xbox's A / DualShock's Cross to be the game's (Switch) B.
  • Xbox's B / DualShock's Circle to be the game's (Switch) A.
  • Xbox's X / DualShock's Square to be the game's (Switch) Y.
  • Xbox's Y / DualShock's Triangle to be the game's (Switch) X.
• Due to hooking SteamInput to provide Keyboard and Mouse input, a controller that SteamInput detects has to be present for keyboard and mouse to work. This can be a virtual controller (for example Virtual Controller / vJoy seems to be working just fine when using vXbox).
• If you extend draw distance usinf far plane value and notice outlines bugging out when up close, make sure to adjust the outline distance value.
