That version has been around since the beginning of time...or at least as long as I can remember, and it's always been my preferred version. Maybe because..as you say...it's easier. Well it's easier if you're good at Pac-Man. I've seen people who are TERRIBLE at it because she moves SO fast they simply can't control her and are too slow on the reaction to either turn Ms. Pac around or turn down the tunnel they want...whatever.
In MAME it used to be a dip switch setting, but a few versions ago, it became it's own rom. mspacmnf I belive is what it's called. there's also a pacmanf that's fast Pac-Man. The Hack is also available on Jr. Pac-Man, although I've never seen it in MAME, only on the Arcade machine. The one in my basement has the fast Jr. Pac roms..if they need to be copied...someone let me know.
