The DLLS.tab file contains a table listing the regions of DLLS.bin that contain each DLL as well as the .bss size of each DLL.
The file starts with a header as follows:
| Offset | Name | Type | Description |
|---|---|---|---|
| 0x0 | bank1Index | s32 | Entry index where bank 1 starts. |
| 0x4 | bank2Index | s32 | Entry index where bank 2 starts. |
| 0x8 | - | s32 | Unknown. |
| 0xC | bank3Index | s32 | Entry index where bank 3 starts. |
After the header is a list of DLL entries terminated by 0xFFFFFFFF_FFFFFFFF at the end of the file:
| Offset | Name | Type | Description |
|---|---|---|---|
| 0x10 | entry[0] | DLLSTabEntry | A DLL entry. |
| ... | ... | ... | ... |
| - | - | - | 0xFFFFFFFF_FFFFFFFF |
Where each entry (DLLSTabEntry) is:
| Offset | Name | Type | Description |
|---|---|---|---|
| 0x0 | offset | s32 | Offset of DLL in DLLS.bin. |
| 0x4 | bssSize | s32 | Number of bytes to be allocated for the DLL's .bss segment. |
The final entry is not an actual DLL. Instead, it exists just to provide the end offset for the previous entry.
DLLs are split up into four banks. The ID of a DLL contains both its bank and its index within the bank.
IDs are mapped to each bank as follows:
| ID Range | Bank |
|---|---|
| [0, 0x1000) | 0 |
| [0x1000, 0x2000) | 1 |
| [0x2000, 0x8000) | 2 |
| [0x8000, EOF) | 3 |
For example, an ID of 0x2004 would be a DLL in bank 2 with an index of 4 (0x2004 & (~0x2000)).
