Hi,
The Novag Constellation has some trouble with take back function ("Remis bug",
https://www.schach-computer.info/wiki/index.php/Bugs).
This patch fixes it.
In "8314_orange" rom, change
Code:
0C8E : A5 06
0C90 : C9 10 D0 0B CE B5 02 AD
0C98 : AA 02 F0 03 CE AA 02
.
by
0C8E : AD AA
0C90 : 02 F0 03 CE AA 02 A5 06
0C98 : C9 10 D0 03 CE B5 02
The new checksums are :
("8314_orange", 0xe000, 0x2000, CRC(F62031DC) SHA1(E367889265B8DDBD50D627ACCB110843333B3CD3)
Cordialy,
