We are talking about input-lag here and the thing is, if people never experienced a "more" input-lag free MAME distro like GroovyMAME for example or even better a original PCB, they will never know or feel, what this topic is all about. Thats because people get used to the input-lag and so they think, everything is fine.
Once you start playing with a MAME distro with less input-lag and ideally with a CRT setup, you will notice the difference, mostly with sounds or music and if you are really good in fast paced games like shmups, obviously also with the input strokes.
