Majiro formats

Wiki Page	Extensions	Description
Arc archive	`.arc`	Archives for all Majiro files of a specific kind
Rct image	`.rct`	Images with 24-bit RGB color
Rc8 image	`.rc8`	Images with 8-bit indexed color (often used as `.rct` alpha channel)
Mjo script	`.mjo`	Bytecode scripts for scenarios and library functions

Wiki Page	Description
CRC hash	32-bit and 64-bit name hashes used for faster lookup
XOR cipher	Encryption by XOR'ing bytes with a key

These are the data types present when explaining file specifications.

Type	Primitive
`byte`	1-byte unsigned integer
`uint16`	2-byte unsigned integer
`uint32`	4-byte unsigned integer
`uint64`	8-byte unsigned integer
`sbyte`	1-byte signed integer
`int16`	2-byte signed integer
`int32`	4-byte signed integer
`int64`	8-byte signed integer
`bool`	1-byte boolean (always `0` or `1`)
`bool32`	4-byte boolean (always `0` or `1`)
`float32`	4-byte single-precision floating point

Type	Data
`byte[n]`	Array of `n` bytes
`char[n]`	Fixed-length string of `n` bytes
`cstring`	Null-terminated string

Primitive types are read in little-endian byte order.
String data types are read in Shift JIS (Codepage 932) text encoding.
The char[n] data type uses null characters as padding.
Italicezed types are not fixed in length, and their size must be determined while reading the file.
