Yes, "Merry Cook" should be identical to G&W Chef. You can probably add Chef along with it like I did with Mickey Mouse and Egg when I added Nu pogodi to MAME. Just marked as bad dump.

Climber LCD segments look identical to the new wide screen one.
NWS one is a little larger, but the outer edge is obscured by the bezel, noticeable on the upper and lower vines.
