  (e.g. "steamapps\common\MGS1" or "steamapps\common\METAL GEAR SOLID 4\MGS1" for Steam games).

Steam Deck/Linux additional instructions

• Open up the Steam game properties and put WINEDLLOVERRIDES="dinput8=n,b;d3d11=n,b" %command% in the launch options.

Configuration

• See MGSM2Fix.ini to adjust settings for the fix.

Modding (MGS 1; Ketchup)

'Ketchup' is a mod loader for MGS 1 in the Master Collection.

It currently supports PPF3 format mods to each ISO under the following folders in the "steamapps\common\MGS1" directory:

  mods\INTEGRAL\INTEGRAL\0\
  mods\INTEGRAL\INTEGRAL\1\
  mods\INTEGRAL\VR-DISK\
  mods\VR-DISK_US\
  mods\VR-DISK_EU\
  mods\MGS1_JP\0\
  mods\MGS1_JP\1\
  mods\MGS1_US\0\
  mods\MGS1_US\1\
  mods\MGS1_UK\0\
  mods\MGS1_UK\1\
  mods\MGS1_DE\0\
  mods\MGS1_DE\1\
  mods\MGS1_FR\0\
  mods\MGS1_FR\1\
  mods\MGS1_IT\0\
  mods\MGS1_IT\1\
  mods\MGS1_ES\0\
  mods\MGS1_ES\1\

Where 0 and 1 refer to disk 1 and disk 2 respectively.

See makeppf for creating PPF3 patches/mods. PPF3 mods derived from original PSX CD releases should work correctly with Master Collection.

If your mods conflict with the built-in Master Collection patches, for the time being it may be useful to enable the DisableRAM and DisableCDROM settings in MGSM2Fix.ini. Once all of the Master Collection patches have been identified and grouped (please help, there are lots!) this heavy-handed approach should no longer be necessary.

Additional mod formats may be supported in future.

Known Issues

Please report any issues you see. This list will contain bugs which may or may not be fixed.
