I'm sure someone on r.g.v.a.c can give you more info on those kinds of
kits. If you don't have a problem adding a couple buttons to your
control panel, you can just convert the game to use one of the newer
mulit-game boards that has Galaga and all the really good stuff on it.
I like those boards, but the only drawback is you NEED a 4 way
joystick for the Pac series to work, and that works fine for Galaga
and such, but can be a pain on a few of the other games that did allow
an 8 way. But an 8 way in a Pac just WILL NOT WORK, trust me.

As far as the legal stuff goes on the mods, I'm pretty sure that Namco still
holds the rights to Pac-man and all the associated games. They've pretty
much forced all the mod chip makers out of business using the copy write to
threaten most out of production. The one exception to this seems to be the
speed chips. They apparently don't mind you changing the clock speeds for
parts of the games.
Back to your original issue... you're best option if you want more games
without having several cabinets is to pick up a cheap cabinet with about 6 -
8 buttons and two joysticks and paint it to look like a Mrs. Pac-man. Once
you've got the look just drop in a power supply and a JAMMA wire harness.
If you want to use your current Mrs. Pac board they have a JAMMA adapter you
can buy for the game to make it plug right up. When you're tried of Mrs.
Pac just pick up another game from e-bay for a reasonable price and swap it
out like a Nintendo game cartridge, so long as they're JAMMA standard
they'll plug up and work just fine without further modification or wiring.
Now granted I've made this process sound pretty simple, but in all honesty
it really isn't all that hard to wire, it just looks worse than it really is
till you get into it. Better yet, most cabinets come pre-wired for JAMMA
these days.
Hope that helps,
Matt
