Save Struct

The save file got a 0x10 bytes header and a byml file after that. Header struct is:

Offset	Size	Description
0x00	u32	CRC32 checkum from 0x04 to EndOfFile
0x04	u32	Version? (Always 0x01)
0x08	u32	Save file size
0x0C	u32	Byml section size

Data

To parse the byml, you have to use byml-v2.py by leoetlino to get an object with all the save value inside. This looks like:

{
    'AchievementSaveData': [{
        'GetTime': 1510358823,
        'IsGet': True,
        'Name': 'Scenario_Ending'
    }, {
        'GetTime': 1514860862,
        'IsGet': True,
        'Name': 'Scenario_WorldAll'
    }, {
        'GetTime': 1512769379,
        'IsGet': True,
        'Name': 'Shine_Gather_1'
    }, {
        'GetTime': 1512769388,
        'IsGet': True,
        'Name': 'Shine_Gather_2'
    }, {
        'GetTime': 1514860870,
        'IsGet': True,
        'Name': 'Shine_Gather_3'
    }

... and more

Editing

After modified the byml object data, you have to convert back the object to the binary byml and then rewrite the sizes stored in the header. You don't need to recompute the save checksum since the game don't check it! (I haven't try to set it to 0x00000000)

Config & Script

TODO

Right now the current script support edit of Coins, purchasable Items / Clothes / Caps / Stickers. There are a lot of values who can be edited too, like the collectibles coins, stars, etc... You can get the byml object content by uncomment this line and then read it in sd://EdiZon/EdiZon.log.
