I know of one RNG table (0-255) that goes 177, 202, 238, ..., 171, 176, 12. This baby is to my knowing often used for various randomness in fields but not for randomness on the world map.
Apart from the just mentioned one I only know of one other RNG table and it goes 99, 6, 240, ..., 199, 106, 202 but that isn't it either it seems.
Anyone happen to know which RNG table is used for worldmap randomness?
