I put a text file with the rom name in the mythgame rom launch path (I 
don't want to display my entire romset in mythgame) and this seems to 
launch sdlmame roms okay, even though the config file"mame.ini" points 
to a romset elsewhere - on launching it complains that some rom files 
may be missing, but this doesn't stop them launching (if you get my 
drift). However it relatively easy, and perhaps more elegant, to 
truncate the string sent to mame to remove the path - I do this to 
launch aae, which is a vector arcade emulator that runs under wine. My 
script to start aae that mythgame points to is as follows:

#!/bin/bash
qjoypad "aae" &
export LD_LIBRARY_PATH='/home/mythtv/.wine/drive_c/"Program Files"/aae'
cd /home/mythtv/.wine/drive_c/"Program Files"/aae
wine aae.exe "${1##/*/}"
# strips out longest string between / and / ie removes the path - so no 
path will be sent to aae, just rom name
xrandr -s 1680x1050
qjoypad "mythtv" &

So if you write your own script to call mame with something similar it 
should work ie. write a script that goes:

#!/bin/bash
mame "${1##/*/}"

and this should strip out the path info that mythgame sends to mame. 
Save the script as start_mame (or something) and in the mythgame command 
configuration tell it to launch mame with:

start_mame s%
