What's the state of Propeller Simulators?

For a time, I used GEAR.

I'm in a position now where I would like to write some basic code, don't need it to run on a Prop, but I do need to see basic outputs, such as just a pin state, or a serial text output.

There are some projects, but I've not followed them closely. Can a few of you, who are either doing this, or are interested / following the work to date, summarize what we have today?

Is it possible to just write SPIN + PASM and have it execute on a emulation and be somewhat productive?

I want to do things like write small PASM loops, and just insure that program flow and result are what is expected. Nothing complex, or bleeding edge.

    Dave Hein's SpinSim has several nice features for code (no physical pin emulations).
    It is a productive environment for me; I prefer the command line environment in many ways.

    SpinSim has "List executed instruction" ability, but it could be a little more verbose especially regarding source and destination values. I use my debugger when I want full interactive access to the simulation for debugging code.
    SpinSim Version 0.25
usage: spinsim [options] file
The options are as follows:
     -l  List executed instructions
     -p  Use PASM Spin interpreter
     -#  Execute # instructions
     -P  Profile Spin opcode usage
     -m# Set the hub memory size to # K-bytes
     -c  Enable cycle-accurate mode for pasm cogs

    BMA debugger example: 
    C:\Propeller\spinsim025>spinsim BMADebugger_Demo.binary

    You can download SpinSim at http://forums.parallax.com/showthread.php?127976-Spin-Simulator . It supports serial and file I/O through the use of the conio.spin and fileio.spin objects. I provide a Windows DOS exe file, but it can also be compiled to run under linux.
