If I'm not mistaken, 星洲炒米 is one of Malaysia fry noodle. This noodle only can find in Kuala Lumpur area. I don't know the history, but this is what Malaysian believe. Singapore can not find proper 星洲炒米. In Hong Kong, it is not common. However, in Kuala Lumpur, it is available from any restaurant, and same cooking style.
Malaysia style does not put curry powder, but the secret ingredient is ketchup and orion
