The CPY crack was made for the base 1.01 version of PES 2021. You cannot apply official Data Packs (DP 7.0, for example) or season updates. That means you’re stuck with 2020/21 kits, transfers, and squads.

: Konami did not release a "portable" (no-install) version of eFootball PES 2021 Season Update

Despite being labeled a "Season Update," PES 2021 improved significantly upon its predecessor. The game refined the "Finesse Dribble" mechanic, allowing for tighter control in midfield battles. Defending became more about positioning and timing rather than brute force.

Portable versions often remove redundant files (like voiceovers in 10 different languages) to keep the file size down, making it easier to transport.
