Convert some Photoshop resources (GDR and PAT files) to GIMP's

[Krikor]

Hey guys,

I downloaded a .pat created in PS but it is not possible to use it in Gimp.

I'm researching a way around this, and landed on this page via two different external links.

Being a post from 2017 I think that a lot must have changed since then, and that maybe there is a simpler way to do this PS-pat to Gimp-pat conversion.

Here comes an error message:
gimp error
Failed to load data:
Error loading 'C:\...' Texture Patterns.pat': Fatal parse error in pattern file: Unknown pattern format version 65536.

How could I do this conversion (ps to Gimp)?

Thx.

I got the idea to use Photopea online.
Hard to find anything there, but I seem to be having success so far, albeit a tedious task in editing each .pat image one by one.
