.Sh DESCRIPTION
The
.Nm
utility disassembles CHIP-8 binaries into the assembly dialect understood
by the
.Xr c8asm 1
assembler.
It reads the binaries provided as command-line arguments and writes the
corresponding assembly code to the standard output.
If no command-line arguments are provided or the special
.Sq \-
filename is given,
input is read from the standard input.

As a result of the CHIP-8 binary format it is quite common that sprite
data and other sequences of byte-literals will be translated by
.Nm
into instructions.
As a minimal reproducable example, the following sprite data would get
disassembled into a
.Ql stor v0 .

.Dl sprite: db 0xF0 0x55
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
Disassemble a binary:
.Pp
.Dl $ c8dump space-invaders.bin
.Pp
Disassemble output from the
.Xr c8asm 1
assembler:

.Dl $ c8asm tetris.s | c8dump
