Creating Custom Patches

I am trying to create a patch for Yu-Gi-Oh! Decade Duels Plus
I have followed guides about how to do this but everything i do seems to not work
This is the code i want to input into RPCS3 (imported_patch.yml - it gives you all cards
400020F0 00000006
4F3C0004 00000000

And this is the most recent format I have made

Version: 1.2
PPU-b901ae34fcc157817bd277103819f03d2c16843a:
  All Cards x3:
    Games:
      "Yu-Gi-Oh! 5D's Decade Duels Plus":
        NPUB30903: [ All ]
    Author: Ezee03
    Notes: All Cards x3
    Patch Version: 1.0
    Patch:
      - [ be32, 0x400020F0, 0x00000006 ]
      - [ be32, 0x4F3C0004, 0x00000000 ]

Instead of RPCS3 telling me its the wrong format it now gives me this error

·F 0:00:02.872811 SIG: Thread terminated due to fatal error: Unhandled Win32 exception 0xC0000005.

Hoping someone can point out what is wrong with the patch I made
and if there is a problem with it, what can i do to correct this?
Thankyou!
