22 sim65 is the only solution as part of the toolchain to execute code. The
23 binary needs to be compiled with <tt/--target sim6502/ or <tt/--target sim65c02/.
28 The simulator is called as follows:
31 Usage: sim65 [options] file [arguments]
34 -c Print amount of executed CPU cycles
36 -V Print the simulator version number
37 -x <num> Exit simulator after <num> cycles
40 --help Help (this text)
41 --cycles Print amount of executed CPU cycles
42 --verbose Increase verbosity
43 --version Print the simulator version number
47 <sect1>Command line options in detail<p>
49 Here is a description of all the command line options:
53 <tag><tt>-h, --help</tt></tag>
55 Print the short option summary shown above.
58 <tag><tt>-c, --cycles</tt></tag>
60 Print the number of executed CPU cycles when the program terminates.
61 The cycles for the final "<tt>jmp exit</tt>" are not included in this
65 <tag><tt>-v, --verbose</tt></tag>
67 Increase the simulator verbosity.
70 <tag><tt>-V, --version</tt></tag>
72 Print the version number of the utility. When submitting a bug report,
73 please include the operating system you're using, and the compiler
77 <tag><tt>-x num</tt></tag>
79 Exit simulator after num cycles.
83 <sect>Input and output<p>
85 The simulator will read one binary file per invocation and can log the
86 program loading and paravirtualization calls to stderr.
