As of late 2024, Konami has shifted focus to eFootball 2025. The PES 2021 servers are no longer officially supported with Live Updates.

Consequence: The dt80_300e_x64.cpk is now frozen in time. No new official changes will happen to it. Opportunity: This stability is a blessing for modders. Because the file will never revert via a server check, modders can safely rename or replace dt80_300e_x64.cpk permanently. Major community patches (like Football Life 2024) have begun ignoring the original file entirely, using it only as a dummy placeholder while loading 100% custom CPKs.

If you are starting a fresh modded install today, you have two options:

Assumes Windows PC, PES 2021 installed, and you have the dt80-300e-x64.cpk file plus a dpfilelist tool.

  • Place the CPK:

  • Update the CPK load order:

  • Launch and test:

    • Absolutely not.
    The game will either:

    If you want to disable its effect (not recommended), you would need to rebuild all other game data — pointless. Always keep it intact.

    Using tools like CriPackedFileMaker or Dragon Unpacker, modders have dissected this file. Inside, you will find:

    Why is it important? Any mod you install that changes the version of a player’s face or boot that was originally altered in DP 3.0 will conflict with this file.

    | Problem | Likely cause | Solution | |---------|--------------|----------| | Game crashes after adding mods | Conflicting dt80_300e_x64.cpk edits | Restore original from Steam backup or backup folder | | Player names/transfers not updating | Mod not overriding this CPK correctly | Use Sider with livecpk or check DpFileList order | | Missing teams after patch | Patch removed original file | Never delete it – always use add‑on CPKs | | Checksum error in modding tools | Modified original file | Replace with clean version |

    Is it safe to delete? If you are using a mega-patch like SmokePatch, deleting this file will likely result in players on a specific team wearing generic black/white jerseys or the game crashing if the database expects the file to be there. If you installed it manually and don't want the specific kits it contains, you can delete it, but you should regenerate the DpFileList.bin to remove the reference.

    Game Crashes: If your game crashes at the "Team Select" screen or during a match involving the team linked to this ID:

    Virus Scanning: Since this is a file often downloaded from third-party sites (PES Patch sites, blogs, forums), always scan CPK files with an antivirus tool before moving them to your game directory. While the files themselves are data archives, the downloaders/installers wrapping them can sometimes contain unwanted software.

    Many large patches (e.g., VirtuaRED, Smoke Patch, Dream Patch) modify or replace dt80_300e_x64.cpk to add leagues, kits, or faces.

    Since I don't know the exact context (are you sharing the file, asking for help, or announcing a fix?), I have provided three different options. Choose the one that fits your situation.
