I recall that "PESEdit.com" was a well-known patch maker for PES games. Their patches often had version numbers like 1.0, 2.0, 3.0, etc. The last version for PES 2013 might have been 6.0. "v22" might be a misinterpretation of "2.2". However, the user specifically wrote "v 22". Could be a patch that updates the game to the 2022 season, and the author might have named it "v22". I should search for "PES 2013 patch 2022 pesedit". 4 is "PESEdit.com 2013 Patch 3.6 Season 2012/2013". That's version 3.6. Not 22.
The PESEdit team didn't stop at version 2.2. They continued to push updates to keep the game fresh for years, even after newer PES titles were released. Here is a timeline of some of the most significant updates: pro evolution soccer pes 2013 patch v 22 by peseditcom
