Revision as of 21:57, 18 April 2023
File Formats
IDX - Index
Index files are broken up into 2048 byte chunks, which I will refer to as "pages". Index file must be at least 1 page in size, meaning the smallest IDX file will be 2048 bytes, filled mostly with null bytes(00h) if it has 1 or 2 indexes (there are 60 indexes per page in SHARYO.IDX for example).
Header
The first 32 bytes of each page is the "header". The header's first 8 bytes contain the filename, if the filename is less than 8 bytes the remaining bytes will be padded with 20h. After the name is "IDX", followed by 00h as a seperator.
Byte 13 (14th byte) is the "page number", starting with 01h and incrementing each page.
Bytes 14-32 appear to be other informational flags which have yet to be understood.
| Byte # | Description |
|---|---|
| 0-7 | Uppercase ASCII, matches file name, if name < 8 bytes it is padded with 20h |
| 8-10 | 49h 44h 58h, literal: "IDX", Uppercase ASCII |
| 11 | Always 00h, separator or null byte for the string? |
| 12 | Always the same in all headers that are in the same file, often seen: 09h 11h, is this multiplier or record length? |
| 13 | The "page" count, starts at 01h increments by 1 every "header" |
| 14-31 | Other flags |
| 22 | Number of records on this page |
index entry
| Byte # | Description |
