Instructions on how to make newer versions of PCSX2 compatible with this editor.

NOTE: There is a button in the app that will do this process for you automatically if you'd prefer to use that.

PCSX2 has changed the type of compression they use when making save state files over time.  Because of this, this app/editor might not work depending on which version of PCSX2 you have (since the app uses PCSX2 save state files).

This app/editor is compatible with older versions of PCSX2 like 1.6.0, but is not compatible with the newer versions like 2.0.2, 2.2.0, etc.  Here's how to manually edit the PCSX2.ini file to make it compatible.

You should find the file you need to edit (PCSX2.ini) in it's default location: Documents\PCSX2\inis.  You can use Notepad to open and edit it.  You can make a backup copy if you'd like before you make any changes.


If you have PCSX2 version 2.0.2 (and maybe some older versions like 2.0.0?):

Open PCSX2.ini with Notepad.

Search for:

SavestateZstdCompression = true

Change that to:

SavestateZstdCompression = false

Save the file.  Now, any NEW save state files you make from now on with PCSX2 will be compatible with this app/editor.  Probably best to pick a new save state slot so your original save will stay intact.

============================

If you have PCSX2 version 2.2.0 (this is the newest stable version as of now):

Open PCSX2.ini with Notepad.

Search for:

SavestateCompressionType = 2

Change that to:

SavestateCompressionType = 1

Save the file.  Now, any NEW save state files you make from now on with PCSX2 will be compatible with this app/editor.  Probably best to pick a new save state slot so your original save will stay intact.

===========================

It is fine to permanently leave these ini changes, since the only thing that changes is the size of the save state files (they're a little larger).
