dis6502 (flow-tracing disassembler for 6502)
dis6502 is a 6502 disassembler that supports Atari 8-bit and Commodore
executables, as well as raw memory dumps. It attempts to separate code
sections from data by tracing the flow of execution, and supports a config
file for manually defining code sections that aren't reached by the trace.
Note: This is NOT the dis6502 from AtariMax. Although the name is the
same, AtariMax's disassembler is completely different (for one thing,
it's a Windows GUI application).

.SH SYNOPSIS
.sp
dis6502 [\fI\-b\fP | \fI\-l\fP | \fI\-c\fP | \fI\-r <address>\fP] [\fI\-a\fP] [\fI\-p <pfile>\fP] [\fI\-v <address>\fP] [\fI\-7\fP] \fIfile\fP
.SH DESCRIPTION
.sp
Dis6502 disassembles 6502 binary files. Binary formats understood include
Atari binary files (L menu command) and boot files. Equate and control
files can be included via the option to name well known locations and to
control the disassembly process. The output includes a cross reference.
.sp
The disassembly process is a two pass operation: First the program flow
is traced starting with the init and run parameters in the file headers.
The dump routine then prints out the information.
.SH OPTIONS
.INDENT 0.0
.TP
.B \fB\-r\fP \fI<address\fP>
\fIfile\fP is raw binary, located at \fI<address>\fP\&.
.TP
.B \fB\-b\fP
\fIfile\fP is an Atari boot image (disk or cassette). Note that neither .ATR
nor .CAS images are supported: the file must be a raw image with no header
information. For disks, this is called an XFD file.
.TP
.B \fB\-l\fP
\fIfile\fP is an Atari load file (aka XEX).
.TP
.B \fB\-c\fP
\fIfile\fP is a Commodore 64 executable.
.TP
.B \fB\-a\fP
Generate assembly output. Suppresses the addresses and object
code normally printed on each line of output, and omits the
cross\-reference section from the end of the output.
.TP
.B \fB\-p\fP \fI<pfile>\fP
Use predefinition file. See \fBFILE FORMAT\fP for the predef file format.
Up to 10 \fB\-p\fP options may be included.
.TP
.B \fB\-v\fP \fI<address>\fP
Alternate vector address (normally \fB$FFFA\fP). This option only has
any effect with raw binaries (\fB\-r\fP option).
.TP
.B \fB\-7\fP
Mask character data to 7\-bit.
.UNINDENT
.SH FILES
.sp
\fB/usr/share/dis6502/atari8.predef\fP
.sp
\fB/usr/share/dis6502/c64.predef\fP
.sp
Predefinition files for Atari 8\-bit and Commodore 64, containing the usual
system equates.
.SH FILE FORMAT
.sp
Lines in a predefinition file consist of:
.sp
\fBlabel\fP .eq \fIaddress\fP
.sp
\fBlabel\fP .equ \fIaddress\fP
.INDENT 0.0
.INDENT 3.5
Defines a label. The \fB\&.eq\fP and \fB\&.equ\fP forms are equivalent.
.UNINDENT
.UNINDENT
.sp
\fB\&.jtab2\fP \fIlowaddr,hiaddr,count\fP
.INDENT 0.0
.INDENT 3.5
Defines a table of \fIcount\fP pointers, split into low and
high byte tables. In assembly code, such a table might look like:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
; func1, func2, func3 are addresses.
table_lo: .byte <func1, <func2, <func3
table_hi: .byte >func1, >func2, >func3
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
To disassemble these, assuming the address of \fItable_lo\fP is \fB$1000\fP,
use:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
\&.jtab2 $1000,$1003,3
.ft P
.fi
.UNINDENT
.UNINDENT
.UNINDENT
.UNINDENT
.sp
\fB\&.rtstab\fP \fIlowaddr\fP,*hiaddr*,*count*
.INDENT 0.0
.INDENT 3.5
Like \fB\&.jtab2\fP, but each entry contains the target address minus one, for use with RTS.
.UNINDENT
.UNINDENT
.sp
\fB\&.trace\fP \fIaddress\fP
.INDENT 0.0
.INDENT 3.5
Causes the trace process to continue at \fIaddress\fP\&.
.UNINDENT
.UNINDENT
.sp
\fB\&.stop\fP \fIaddress\fP

Disassemble 6502 object code
----------------------------
:Manual section: 1
:Manual group: SlackBuilds.org
:Date: |date|
:Version: |version|
SYNOPSIS
========
dis6502 [*-b* | *-l* | *-c* | *-r <address>*] [*-a*] [*-p <pfile>*] [*-v <address>*] [*-7*] *file*
DESCRIPTION
===========
Dis6502 disassembles 6502 binary files. Binary formats understood include
Atari binary files (L menu command) and boot files. Equate and control
files can be included via the option to name well known locations and to
control the disassembly process. The output includes a cross reference.
The disassembly process is a two pass operation: First the program flow
is traced starting with the init and run parameters in the file headers.
The dump routine then prints out the information.
OPTIONS
=======
**-r** *<address*>
*file* is raw binary, located at *<address>*.
**-b**
*file* is an Atari boot image (disk or cassette). Note that neither .ATR
nor .CAS images are supported: the file must be a raw image with no header
information. For disks, this is called an XFD file.
**-l**
*file* is an Atari load file (aka XEX).
**-c**
*file* is a Commodore 64 executable.
**-a**
Generate assembly output. Suppresses the addresses and object
code normally printed on each line of output, and omits the
cross-reference section from the end of the output.
**-p** *<pfile>*
Use predefinition file. See **FILE FORMAT** for the predef file format.
Up to 10 **-p** options may be included.
**-v** *<address>*
Alternate vector address (normally **$FFFA**). This option only has
any effect with raw binaries (**-r** option).
**-7**
Mask character data to 7-bit.
FILES
=====
**/usr/share/dis6502/atari8.predef**
**/usr/share/dis6502/c64.predef**
Predefinition files for Atari 8-bit and Commodore 64, containing the usual
system equates.
FILE FORMAT
===========
Lines in a predefinition file consist of:
**label** .eq *address*
**label** .equ *address*
Defines a label. The **.eq** and **.equ** forms are equivalent.
**.jtab2** *lowaddr,hiaddr,count*
Defines a table of *count* pointers, split into low and
high byte tables. In assembly code, such a table might look like::
; func1, func2, func3 are addresses.
table_lo: .byte <func1, <func2, <func3
table_hi: .byte >func1, >func2, >func3
To disassemble these, assuming the address of *table_lo* is **$1000**,
use::
.jtab2 $1000,$1003,3
**.rtstab** *lowaddr*\,*hiaddr*\,*count*
Like **.jtab2**, but each entry contains the target address minus one, for use with RTS.
**.trace** *address*
Causes the trace process to continue at *address*.
**.stop** *address*
Causes the trace process to stop at *address*.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct. It's also
# customary to leave one space after the ':' except on otherwise blank lines.

dis6502: dis6502 (flow-tracing disassembler for 6502)
dis6502:
dis6502: dis6502 is a 6502 disassembler that supports Atari 8-bit and Commodore
dis6502: executables, as well as raw memory dumps. It attempts to separate code
dis6502: sections from data by tracing the flow of execution, and supports a
dis6502: config file for manually defining code sections that aren't reached
dis6502: by the trace.
