Background:
I'm attempting to reenable the party chat feature in the US version of DQ4r.  I did some tracing with no$gba and found the routine that handles the party chat button (X) in the Japanese version and also the place in the US ROM that should handle party chat. 

So my problem lies in getting a useful trace log from the Japanese version so I can isolate the differences and see if it is possible to add the routine to the US version.  You can give no$gba an address to start logging from but it doesn't really trace, it just prints a disassembly in order.   Please advise, thanks. :>
