Compressed/Binary size can be 0 or lower than expected, this is the case for BSS for example.

Compression

The compression used here is BLZ, with a modified footer since 3ds. The footer is now 0xC bytes instead of 0x8, and has the form u32 compressed_data_len; u32 footer_size; u32 additional_len_when_uncompressed;
