sim65 Users Guide <author><url url="mailto:polluks@sdf.lonestar.org" name="Stefan A. Haubenthal"> <abstract> sim65 is a simulator for 6502 and 65C02 CPUs. It allows to test target independed code. </abstract>  <toc>  <sect>Overview sim65 is the only solution as part of the toolchain to execute code. The binary needs to be compiled with <tt/--target sim6502/ or <tt/--target sim65c02/. <sect>Usage The simulator is called as follows: <tscreen><verb> Usage: sim65 [options] file [arguments] Short options: -h Help (this text) -c Print amount of executed CPU cycles -v Increase verbosity -V Print the simulator version number -x <num> Exit simulator after <num> cycles Long options: --help Help (this text) --cycles Print amount of executed CPU cycles --verbose Increase verbosity --version Print the simulator version number </verb></tscreen> <sect1>Command line options in detail Here is a description of all the command line options: <descrip> <tag><tt>-h, --help</tt></tag> Print the short option summary shown above. <tag><tt>-c, --cycles</tt></tag> Print the number of executed CPU cycles when the program terminates. The cycles for the final "<tt>jmp exit</tt>" are not included in this count. <tag><tt>-v, --verbose</tt></tag> Increase the simulator verbosity. <tag><tt>-V, --version</tt></tag> Print the version number of the utility. When submitting a bug report, please include the operating system you're using, and the compiler version. <tag><tt>-x num</tt></tag> Exit simulator after num cycles. </descrip> <sect>Input and output The simulator will read one binary file per invocation and can log the program loading and paravirtualization calls to stderr. Example output for the command <tscreen><verb> sim65 --verbose --verbose samples/gunzip65 </verb></tscreen> <tscreen><verb> Loaded `samples/gunzip65' at $0200-$151F PVWrite ($0001, $13C9, $000F) GZIP file name:PVWrite ($0001, $151F, $0001) PVRead ($0000, $FFD7, $0001) PVOpen ("", $0001) PVRead ($0003, $1520, $6590) PVClose ($0003) PVWrite ($0001, $13D9, $000F) Not GZIP formatPVWrite ($0001, $151F, $0001) PVExit ($01) </verb></tscreen> <sect>Copyright sim65 (and all cc65 binutils) are (C) Copyright 1998-2000 Ullrich von Bassewitz.
