I am happy with the .127 as it still used the Donkey Kong samples, and it sounds better than the emulated discrete circuits. Would the button speed cheat still work on the Pac-Man games if you moved to the newer version? I like the button turbo better than the always on or always off, as my area had a few of them before I saw the first always on version.
Just my 2 cents...
BTW... FWIW.... I am the Scotty that created both NewPuck2 (the recreation, not the real version found in Mame) as well as Pac-Man After Dark (with the Oh Shit!). You have it incorrectly labeled as Scott Lawrence for PMAD and Midway as NP2. Scott Lawrence and I are not the same person. It is not a big deal if you want to leave it as is, as those are the only two I did years ago, and just did it as a hobby for fun, and never bothered to write to you and mention when you were asking for names of who did what a few years back.
