The rest is all Malaya (Singapore being part of Malaysia).
Singapore was part of Malaysia for only 2 years from 1963 to 1965. Before that, Singapore wasn't part of Malaya. It was first a British East India Company trading port, then part of the Straits Settlements (incorporating Malacca and Penang but distinct from Malaya), then a British Crown Colony with the independence of Malaya in 1957. For many nonya dishes, Malacca, Penang and Singapore could lay common and competing claims to originality, but I think that none are so silly as to bicker over such things.
