Yes, I had done the same, so my question was whether the same could be done in a street fighter (with turbo HD or 3DO music) or king of fighters (with neogeo cd music).
In Mame2003 you can change with a very similar method some music, Final Fight, Michael Jackson, etc ...
But of course, all this is time and work, and the developers already have enough with what there is that today is incredible.
