Hey Hoagie,
Here you go!  Change the file from myconfig.txt to myconfig.zip,  I wasn't sure if it would post as a zip or not since I have no way of hosting the file?
The only files I didn't include in this are my modded system.ini files,  you should be able to change yours to work though.  Also, remember to make a back up copy of your system.ini file before modding it.  
 I basically made two directories in my mamewah directory one that contained an orignal System.ini file in a directory called windows and another that contained the modded system.ini, which I called mamewah.   You just want to modify your shell in the system.ini file and change it from explorer to mamewah.   I've included a few other things in the zip, such as my autoexec.bat, config.sys, advmame.rc etc etc and also my two shutdown programs.  Let me know if you have any questions?
Steve
