As of 2025, the 0.139u1 set is maintained only by hardcore preservationists. With the rise of MAME "Rollback" ROMs for arcade netplay (fightcade, etc.), the u1 specification has found a second life.

Furthermore, the "patched" concept has evolved. Modern patches focus on widescreen hacks (hacking the draw distance for horizontal monitors) and analog control fixes for light guns.
