I don't think you need to recompile mame to remove screen from 0.84.
Try to run mame with parameter -skip_disclaimer -skip_gameinfo
ex :
mame pacman.zip -skip_disclaimer -skip_gameinfo
you can also , i think disable from ini file.
Generate the mame.ini file (if you don't have it) using that command : mame -cc
Then look in the file , search for disclaimer and gameinfo and change the value to 1 or 0 .
