Yes! You are write. I haven't mentioned this. It's a good idea to swap them all in the form that black has the move-right. Thank you!
I'll fix that. But not today ;) If you find any inconsistencies in the data please let me know! By the way: I forgot to cut the file at the end. You should only use the values of pattern with an ID < 0x40000. ÁB> Thanks for the file! This should be very helpful when I try to reproduce results.
