Module dbs 

DBS (Siglus database) loader.

This module implements the .dbs expansion and table access logic used by the engine runtime.

File layout (on disk):

• i32 type (little-endian)
• payload[...] : obfuscated LZSS stream

Expansion algorithm (tnm_database_expand):

1. XOR payload as u32 stream with XORCODE[2].
2. LZSS-unpack payload into unpack_data.
3. Apply a tiled binary mask split into A/B using tile_copy semantics.
4. XOR A with XORCODE[0], XOR B with XORCODE[1].
5. Re-composite A/B back into the final expanded buffer using the same mask.

Expanded buffer layout (in memory):

• S_tnm_database_header at offset 0
• row headers table (array of S_tnm_database_row_header)
• column headers table (array of S_tnm_database_column_header)
• data table (row_cnt * column_cnt DWORDs)
• string table

String encoding:

• If type == 0: strings are multibyte (typically Shift-JIS) and NUL-terminated.
• Else: strings are UTF-16LE (TCHAR) and NUL-terminated.
