In any case, microwine loads the eval function into 0x46adc0, and the function runs to 0x46bfb3.

For the purposes of comparison I looked at the evaluation Rybka 2.3.2a again. There are a few differences from the Fruit evaluation features as used in Rybka 1.0 Beta. There is "pawn endgame" code, "anti-mobility" for pawns that can't move, no bonus for knight mobility, and a version of the "drawish" indicator from the pawn structure. The 32-bit field to combine two 16-bit opening/endgame scores is present also. Other than these, it seems to be the same as previously, with some of the internal PST scaling from Fruit also still extant.
