Prerequisites

• Devil May Cry 4 Special Edition
• Latest version of ddmk

Instructions

1. Extract the contents of ddmk_2.7.3_release.zip somewhere safe.

2. Copy the contents of 4 from ddmk_2.7.3_release.zip into the root folder of DMC4SE.

• To find the game's root folder, simply head into the game page in your Steam library -> Manage -> Browse Local Files

3. Extract these files from dmc4_downgrade.zip into the root folder of DMC4SE:

• diff_DevilMayCry4SpecialEdition
• diff_steam_api

4. Copy and paste DevilMayCry4SpecialEdition.exe in the same location, and rename it to something else e.g. source_DMC4SE.exe.

5. Do the same thing with steam_api.dll (copy & paste, rename e.g. source_steam_api.dll).

6. Open terminal and direct it to DMC4SE's root folder using cd.

7. Run this command (using name example from step 4):

xdelta3 -f -d -s source_DMC4SE.exe diff_DevilMayCry4SpecialEdition DevilMayCry4SpecialEdition.exe

8. Afterwards, run this command (using name example from step 5):

xdelta3 -f -d -s source_steam_api.dll diff_steam_api steam_api.dll

9. Use protontricks to install Consolas. You can either:

• (GUI) Select DMC4SE -> Select the default wineprefix -> Install a font -> Choose consolas, or
• (terminal) Run this command (assuming you set an alias called protontricks):

protontricks 320950 consolas

9. Open the game's Properties and paste this:

DXVK_ASYNC=1 WINEDLLOVERRIDES="dinput8=n,b" %command%

If you get the following error on step 7:
"xdelta3: target window checksum mismatch: XD3_INVALID_INPUT"

Try adding -n to the command, this ignores the checksum validation, so the command should look like "xdelta3 -f -d -n -s source_DMC4SE.exe diff_DevilMayCry4SpecialEdition DevilMayCry4SpecialEdition.exe"
