blue prince game pass to team transfer.md

The below extract is from https://old.reddit.com/r/BluePrinceUncensored/comments/1pnzbp1/transfer_a_game_pass_save_to_steam_blue_prince/

It was previously in this thread https://old.reddit.com/r/BluePrince/comments/1jx4ktx/blue_prince_save_data_locations_moving_from_game/

But the morons in the r/blueprince moderation team decided, in their infinite wistom, that transfering the game from gamepass to steam was "unintended" (by someone, obviously not the dev himself as he made the pw the same as the computers from the game) and therefore the directions are state secrets or whatever.

Anyway, fuck those cunts. Heres a copy of the instructions:

I successfully transferred my Blue Prince save from Game Pass (PC) to Steam, so I’m sharing the full process here to help others.

This worked for me on Windows.

1. Locate the Game Pass save

Go to the Game Pass save directory (yours will look very similar, IDs may differ):

C:\Users\[USERNAME]\AppData\Local\Packages\RawFury.BluePrince_9s0pnehqffj7t\SystemAppData\wgs\000901F39906ACFA_0000000000000000000000007D0295B9\C0E8BF09D7A746458CBD6649D24C79DFI 

Inside this folder:

• There may be multiple files
• The correct save is the largest file (usually no extension)

2. Decrypt the save (Game Pass format)

Go to: https://es3.tusinean.ro/

Decryption section

• Upload the file you copied
• Password: swansong
• Decrypt and download the resulting file

3. Re-encrypt the save for Steam

On the same website, use the Encryption section:

• Upload the decrypted file
• Password (Steam encryption key):D#vnrl%TI_9q0euFPIx+wKRuNx%Aja2-AtuH1jtMSk2k%H1jXjUPor08QaeQE=p5l=LAIWaSYms-68SYVS0PPoWxgM1B8?8tirM+UGr=cp!5a3=B5tBsKYEUfqxN!H9DvRVkLW?6cMeZWxgov%OOXmfl9zRiqWPsXq95lEc4yax7hqf5m_i5ssn-OGgLA8LJu2ETibBi7DwLc-zQ4M9jRGIdV_izS_J_=3FA=rAo0HUiEr-HWYVnuK$OQUyaVMchXxf%EBo3A7Z-PXYm$6PPG%fJfWzV7M$L5he#y5cb?kVR67IfGzG$UzBcLhNMDhQFwQSEX59ZG7hP32q?6PgirmvGTd-45+7ZKyG$FrDHoNw7ceUhrxYdzYSHd0yRz0T_RR_R5$GZda%DDfCUPHIaVlIhMq4FEOzo?GL7wyXr9XD7SD_QGpjZh&NDwycjnBeOy2mmFazlOV5eR7jsiwYDde9jCOH&cOxeTody=iUEt|l7JCQ8IyX|0g3H&NO6DMveVqC9|OPkOZpO3DpM|||3LJ7PX40rZJXmLILu0UXU9hpM5
• Encrypt and download the file

4. Rename and move to Steam

Rename the encrypted file exactly to:

MtHollyBlueprint.es3

Then copy it into the Steam save folder:

C:\Users\[USERNAME]\AppData\LocalLow\Dogubomb\BLUE PRINCE\storage

Replace the existing file if prompted.

5. Launch the game

Start Blue Prince on Steam.
The save should now appear correctly.

Notes

• Make sure the game is closed during the entire process
• The Steam encryption key may not work for 100% of users, but it worked in my case
• Always keep a backup of your original save

I got banned from the official sub for this post, even though it’s about ownership of your own save files and basic common sense. Hope this helps others.
