define modern.
if a game is still sold for arcades, it does not get into MAME if it's not sold anymore for arcades and it's newer than ~3 years, it does not get into MAME
if it's older than 3 years or it's not sold anymore for arcade, the company can hardly being damaged by emulation (especially emulation at ~3FPS, like emulation of a Pentium 3 would be at best)
