'''BEA''' ('''B'''ezel '''E'''ngine '''A'''rchive) is a file format used by [[Nintendo Switch]] games that is developed with Nintendo's game engine [[Bezel Engine]], for example [[Super Mario Party]]. Each sub file is compressed using ZStandard.

= File Format =
== Header ==
The file starts with the following header:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[8] || '''File magic'''. Always ''SCNE\0\0\0\0'' in ASCII, or 53 43 4E 45 00 00 00 00.
|-
| 0x08 || UInt32 || '''[[#Version List|Version number]]'''.
|-
| 0x0C || UInt16 || {{BOM}}
|-
| 0x0E || Byte || '''Alignment shift'''. 2 raised by this value is the alignment required by this file when loaded into memory.
|-
| 0x0F || Byte || '''Target address size'''. Size of a pointer in bits. Never set and there remains 0.
|-
| 0x10 || UInt32 || '''Dummy value'''.
|-
| 0x14 || UInt16 || A '''flag''' which is only used on runtime. One bit sets wether the file is relocated.
|-
| 0x16 || UInt16 || Offset to the '''first section'''.
|-
| 0x18 || UInt32 || '''[[#Relocation Table|Relocation table]] offset'''.
|-
| 0x1C || UInt32 || '''Size until start of file data''' in bytes.
|-
| 0x20 || Int64 || '''Number of [[#Sub File|sub files]]''' in this archive.
|-
| 0x28 || Int64 || '''Sub file offset table offset'''. Points an array of offsets which points to each [[#Sub File|sub files]].
|-
| 0x30 || Int64 || '''Sub file DICT offset'''. Points to a [[#Dictionary|dictionary]] containing the sub file names.
|-
| 0x38 || Int64 || {{Unknown-left|'''Unknown'''. Only seen as 0.}}
|-
| 0x40 || Int64 || '''Archive name offset'''.
|}

== Sub File ==
Each sub file contains ZStandard-compressed data. Each entry has the following structure:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''ASST'' in ASCII.
|-
| 0x04 || UInt32 || '''Next section offset'''.
|-
| 0x08 || UInt32 || '''Size of this section''' in bytes.
|-
| 0x0C || UInt32 || '''Reserved'''.
|-
| 0x10 || UInt32 || {{Unknown-left|'''Unknown'''. Most likely a flag.}}
|-
| 0x14 || UInt32 || '''Compressed file size''' in bytes.
|-
| 0x18 || UInt32 || '''Decompressed file size''' in bytes.
|-
| 0x1C || UInt32 || {{Unknown-left|'''Unknown'''. Only seen as 0.}}
|-
| 0x20 || Int64 || '''Compressed file data offset'''.
|-
| 0x28 || Int64 || '''File name offset'''.
|}

== String Table ==
{{NX String Table}}

== Dictionary ==
{{NX Dictionary}}

== Relocation Table ==
{{NX Relocation Table}}
