On a related note... because I would really love to get this working...
I'm using MAME 0.82, MAMEwah 0.97, Win XP with a super dual box Playstation 2 to USB adaptor with 2 MAS systems sticks attached.  These work perfectly by configuring through the tab menu.
Mame sees my configuration as this:
640
312
WIndows XP sees my configuration (through the game controllers in control panel) as this:
751
324
or something like that (at work 

 I don't have my notes with me.)
I seems like there is some kind of conflict going on between this.  I set up a ctrlr file called default in a folder called mycabinet.  I did this by taking the file that comes with MAME , deleting all the junk at the top and copying and pasting the joycodes I needed.  I had mame pointing to these files but the controls were all garbled.  It seemed to create a combination of  the two.  I don't know what could be the problem.  I worked on this for a night but got extremely frustrated and just deleted everything I did and went back to using the tab menu.  Any advice would be great.
