searchAreaSize

• 0 -> overwrite all apearences

patchType

• 0 -> findAndReplaceCode
• 1 -> replaceCodeAt
• 2 -> usePointerAndReplaceCode
• 3 -> findAndReplaceString
• 4 -> replaceStringAt
• 5 -> usePointerAndReplaceString

patchOffset

• strings -> offset between each character
• code -> offset where to patch based on the target address

processType

• 0 -> ARM9
• 1 -> ARM11

binaryData

The binary data include the following informations in this order:

• patch name
• patch description
• processname
• originalCode or originalString
• patchCode or patchString
