No.05155 Fujix Administrator Nov 13, 2009, 01:16	Do you mean that Pinfu should not be scored because you did Ron with a 7-pin for 8-pin and 9-pin on the edge? If so, generally it's not. But there are some local rules allowing it. Although I think the judge algorithm is originally rude.

No.05161 Fujix Administrator Nov 15, 2009, 02:20	I encountered another wrong Pinfu case, uploaded a screen shot. Usually Pinfu is not scored for "Nobe-tan" hand.

No.05171 Fujix Administrator Nov 16, 2009, 17:44 edited on: Nov 16, 2009, 17:46	I did some more test of this game and it looks like Fu point calculation is incorrect. (Check this page for Fu points details -> http://homepage2.nifty.com/tagoon/html/fukeisan.html ) I uploaded two pictures, the first one is when I won with Tsumo. It addes 2 Fu points, The total is 30 Fu, no Pinfu scoring. The latter one is wrong Fu points. It should be 20 (fuutei) + 10 (ron) + 4 (anko x 1) = 34 and 40 Fu round-up. But 50 points in this case. Some kind of calc bug of the emulator core could cause a problem like this, but I'm not sure at all.
