Lib20070319, a library to read/write Ryu Ga Gotoku Studio's proprietary 20070319 file format

Why the weird name?

The format does not have an official name, so it has been named after its header magic (0x20070319).

Quick demo

For demonstration purposes, let's make some quick edits to Yakuza 0's ability.bin_c file.

It is worth noting that the file encoding must be specified. Some files use UTF-8 encoding for text while others use Shift-JIS. There is no practical way to distinguish them from the file alone, so it is required that the user provides the correct encoding.

The general rule of thumb is that any games released before Yakuza 0 use Shift-JIS, while games released after, 0 included, use UTF-8.

// Open the 20070319 file
Bin20070319 bin = Bin20070319FileReader.ReadBin20070319("ability.bin_c", Encoding.UTF8);

// Print all column names, their internal data type enum and the C# type for that data type
foreach (Bin20070319Column column in bin.GetColumns())
{
	Console.WriteLine($"{column.Name} [{column.InternalDataType}]: {column.GetDataType()}");
}

// Get entry for the "Heat Wave 1" upgrade
Bin20070319Entry entry = bin.GetEntry(112);

// Since we know the "SKILL" column is a String, we can retrieve the value as such
string skillValue = entry.GetValueFromColumn<string>("SKILL");

// This will print "Heat Wave 1"
Console.WriteLine(skillValue);

// Let's edit the value
entry.SetValueFromColumn("SKILL", "Some new skill name");

// Let's also make it free. The "MONEY" column is of type String too, despite holding a numerical value. (Don't look at me, I didn't design this format)
entry.SetValueFromColumn("MONEY", "0");

// Now we can save the edited file
Bin20070319FileWriter.WriteBin20070319ToFile(bin, "edited_ability.bin_c", Encoding.UTF8);
