Actually, if we were to split hairs in half, one could call modifying MAME's code then compiling it "hacking". Not in the recent meaning the word took, but in its original meaning: understanding the way something works with the intent to make it work in a better/more appropriate way. Linux system programmers, for exemple, call themselves "hackers", and they don't work on raw machine code (which would be stupid, as the sources are available). They modify C code (in Linux's exemple) just like what is done with MAME (except MAME modification doesn't require extensive programming skills). Therefore, a modified version of MAME could be called a hacked MAME (maybe it's a little abusive, but not to the point of making it a wrong name for such a thing). Here ends my hair splitting Happy bday again, James <{POST_SNAPBACK}> Nah code was added that was not even there.Unlike Nebula , Kawaks where loaders are needed to bypass the lockouts to prevent you playing newer games. Mame is open source unlike kawaks Nebula NRX.Nothing in Mame needs to be hacked for added games to work.
