Filter[edit]
Content filtering is enabled when this word isn't 0xffffffff. This is only used for the following: if(filterword_u16high!=contentdatatype_u16high || (filterword_u16low & contentdatatype_u16low) == 0)continue; Hence, filterword_u16high must match contentdatatype_u16high, and the bitmask specified by filterword_u16low must be non-zero in contentdatatype_u16low. The contentdatatype is extracted from the extdata filename, which originates from the BOSS-container. The NsDataId for the content entry is only written to the output when processing isn't skipped due to filtering.
Start NsDataId[edit]
This field is only used when starting_wordindex is non-zero or when this field is non-zero.
The NsDataId at the specified start-wordindex must match this field, otherwise error 0xD840F846 is returned. It will then skip normal content entry processing for this matching entry(cur_wordindex is field is increased by 0x1 before starting the content entry processing loop).
Description[edit]
This writes an array of u32 entries(NsDataId) to the output buffer, for the current programID.
This eventually calls a function with the following type parameters: 0, 1, 1. This function doesn't use the second type parameter. Afterwards another function is called using the programID.
