<h1>6502bench SourceGen: Tools</h1>
Add file slicer tool The tool allows you to cut a piece out of a file by specifying an offset and a length. A pair of hex dumps helps you verify that the positions are correct. Also, minor cleanups elsewhere.

<h2><a name="instruction-chart">Instruction Chart</a></h2>
Use relocation data to format instruction operands This was a relatively lightweight change to confirm the usefulness of relocation data. The results were very positive. The relatively superficial integration of the data into the data analysis process causes some problems, e.g. the cross-reference table entries show an offset because the code analyzer's computed operand offset doesn't match the value of the label. The feature should be considered experimental The feature can be enabled or disabled with a project property. The results were sufficiently useful and non-annoying to make the setting enabled by default.

Improve CPU instruction chart Added "show undocumented opcodes" checkbox, so you can choose whether or not to see them at all. (Issue #60) Added formatter call for the instruction mnemonics so they get capitalized when the app is configured for upper-case opcodes. (Issue #59) Fix a bug where the instruction chart and ASCII chart were writing their modes to the same setting, stomping each other. Also, pluralized a button in the file concatenator.

<p>The status flags affected by each instruction reflect their behavior
on the 65816. The only significant difference between 65816 and
6502/65C02 is the way the BRK instruction affects the D and B/X flags.</p>
<h2><a name="ascii-chart">ASCII Chart</a></h2>
<p>This opens a window with the ASCII character set. Each character is
displayed next to its numeric value in decimal and hexadecimal. The
pop-up list at the bottom allows you to flip between standard and "high"
ASCII.</p>

<h2><a name="hexdump">Hex Dump Viewer</a></h2>
<p>You can use this to view the contents of the project data file
by double-clicking the "bytes" column, or with Actions &gt; Show Hex Dump.
The viewer is displayed in a "modeless" dialog that does not
prevent you from continuing to work with the project. If you
double-click a different line in the project, the viewer will automatically
highlight those bytes.</p>
<p>You can also use this to view the contents of arbitrary files by
using Tools &gt; Hex Dump. There is no fixed limit on the number of
viewers you can have open simultaneously. (Be aware that the viewer
currently loads the entire file into memory, and you will run out of room
eventually. Not coincidentally, the viewer has a size limit of 16MiB
per file.)</p>
<p>You can select lines with the mouse as you would in any other list
view. Ctrl+A selects all lines. Ctrl+C copies the selected lines to
the system clipboard.</p>

<p>The "character conversion" selector allows you to choose how the
bytes are converted to characters for the Text column. Choose from

<p>If "ASCII-only dump" is not checked, non-printable bytes are shown in
the ASCII dump as a middle dot ('&#183;'). If the box is checked,
non-printable bytes are represented by a period ('.') instead. The
use of non-ASCII characters makes the dump unambiguous when unprintable
characters are mixed with periods, but the lines may be unsuitable for

<p>The File Slicer allows you to "slice" a piece out of a file, saving
it to a new file. Specify the start and length in decimal or hex. If
you leave a field blank, they will default to offset 0 and the remaining
length of the file, respectively.</p>
<p>The hex dumps show the area just before and after the chunk to be
sliced, allowing you to confirm the placement.</p>
Add instruction chart This adds a window that displays all of the instructions for a given CPU in a summary grid. Undocumented instructions are included, but shown in grey italics. Also, tweaked AppSettings to not mark itself as dirty if a "set" operation doesn't actually change anything.

Fix bank for AbsInd and AbsIndLong addressing The Absolute Indirect and Absolute Indirect Long addressing modes (e.g. "JMP (addr)" and "JMP [addr]") are 16-bit values in bank 0. The code analyzer was placing them in the program bank, which meant the wrong symbol was being used. Also, tweak some docs.

<p>This tool allows you to view Apple IIgs Object Module Format (OMF)
executables, and convert them for disassembly.</p>
<p>OMF executables have multiple segments with relocatable code. References
to addresses aren't filled in until the program is loaded into memory,
which makes it difficult to disassemble the file. The conversion tool
loads the OMF file in roughly the same way the GS/OS System Loader would,
placing each segment at the start of a bank unless otherwise directed.
The loaded image is saved to a new file, and a SourceGen project file is
created with some basic attributes filled in.</p>
<p>Only "Load" files (S16, PIF, TOL, etc) may be converted. Compiler object
