There's also a Sidam version of Galaga (Sidam PCB 11200, official license for the Italian market),
but, unlike Sidam's Dig Dug, this one does not use any unique ROM, but a mix between the two Namco sets:
bottom-10_2532.4d = gg1_11.4d galaga Galaga (Namco rev. B)
bottom-8_2532.4h = gg1_9.4l galaga Galaga (Namco rev. B)
bottom-9_2532.4f = gg1_10.4f galaga Galaga (Namco rev. B)
top-0_2532.3n = gg1-1.3p galagao Galaga (Namco)
top-1_2532.3m = gg1-2.3m galagao Galaga (Namco)
top-2_2532.3l = gg1_3.2m galaga Galaga (Namco rev. B)
top-3_2532.3k = gg1-4.2l galagao Galaga (Namco)
top-4_2532.3j = gg1_5b.3f galaga Galaga (Namco rev. B)
top-6_2532.3e = gg1_7b.2c galaga Galaga (Namco rev. B)
