    "PatchName": "Example DIFFPATCH",
    "AuthorName": "SodaSoba",
    "TargetName": "ORIGINAL.szs",
    "ID": "123456789",
    "Files": [
        {
            "FileName": "blyt/FlcGrpList.bflyt",
            "Patches": [
                {
                    "PaneName": "N_PosAll",
                    "Position": {}
                },
                {
                    "PaneName": "NH_Root",
                    "Position": {
                        "Y": -50
                    }
                },
                {
                    "PaneName": "N_Top",
                    "Position": {
                        "Y": 50
                    }
                }
            ],
            "Materials": [
                {
                    "MaterialName": "T_00",
                    "ForegroundColor": "00000000"
                }
            ]
        }
    ]
}
