Hey Wizard of DelRay, I was considering sending this as a PM however, other people may be interested in the same questions.
I read your customame compliations and was considering using it when I got a chance today or tomorrow.  Reading your site has prompted me to ask a few more questions.
About the skip or speed up frames, can you do this for each individual game or is a global change for all games?  If you can skip X amount of frames for each game, how much of a pain is to do?  Do I have to write an .ini for each one?  
Secondly, about the volume gain/decrease functions, again the same questions, can you do this for each individual game or is a global change?  I have a volume knob on my cabinet and its tedious to adjust for each game, if I could make a change in a .ini one time instead of having to screw with the volume.  MKII for example is ridiculously quiet and if I exit and enter another game I get blasted, hahaha.
Consider me a mame moron and break it down what I need to do into the simpliest steps if you don't mind describing them.
Thanks for your input and I wait for your response!
