Re: A patch for AT mode of the Novag Sapphire
Hello,
Sorry for the late reply, but I was entertaining my family on vacation. I decoded about 750 lines of H8 assembler to make this patch. There were 3 main bugs, including the treatment according to the color to move, and the calculation of the new average time after each move. In the end, I ONLY took the AT mode code from the Sapphire II and adapted it (different offsets) to the Sapphire. For the Emerald Classic Plus, I'll have a look at the code. Cordialy, mychess. |

Hi Mychess!
Similar to your Sapphire patch, I have now also made a patch for the Diamond, which shouldn't be particularly difficult because the two programs are practically identical (apart from the hardware control). The easiest task was to adjust the addresses. Only some values (registers?) were different on the Diamond than on the Sapphire, so I changed those accordingly (these values are ff62/ff65/ff67 in the Diamond but ff60/ff63/ff65 in the Sapphire). Here is an assembly list of my changes - maybe you can take a look at these changes and let me know if everything is ok? I've also attached the modified Diamond ROM with exactly these changes - I've already tried it here in MessNew and it seems to work correctly. Regards, Franz Code:

Hi Fhub,
I don't have the diamond roms so I couldn't make this patch. But you have made a perfect patch. Concerning the Emerald Classic Plus, complicated time management but it seems that the patch is just that: 47E7: 20 (in place of 10) Best Regards. mychess |

But it wasn't very difficult to make it after your Sapphire patch. Zitieren:

"The computer will use half of the specified time to calculate the counter-move and use the remaining time to complete the search. The time varies in the opening game, the middle game and end game position accordingly. The computer tends to play faster in the openings and endgame positions, but in complicated middle game positions it may take longer to make its move. Depending on the position the computer may take up to four times the set time on these levels." from Novag. Best Regards, mychess |

Hi,
ich hab jetzt eine MessNew_Test-Version hochgeladen, die alle 3 Patches für den AT-Level-Bug bei Diamond/Emerald/Sapphire enthält. Falls das jemand testen möchte - hier ist der Link: https://c.gmx.net/@31720685988479052...SP23WQRnVaGfmw Diese Datei braucht man nur über das bestehende MessNew-Verzeichnis entpacken. Die gepatchten Versionen aktiviert man am besten, indem man die Engine(s) direkt in MessNew startet, unter 'File > Show Tab Menu > BIOS Selection' das System 'modified' auswählt, und auf 'Reset' doppelklickt - danach wird diese gepatchte Version auch beim Start in MessChess verwendet. Beim Emerald habe ich noch Zweifel, ob dieser Patch auch tatsächlich etwas bringt - irgendwie erscheint mir diese 1-Byte-Änderung zu einfach!? Außerdem merke ich eigentlich auch beim originalen Emerald diesen angeblichen AT-Level-Bug nicht wirklich (oder er setzt erst viel später ein als ich bisher probiert habe). Grüße, Franz |

Also würde ich immer noch empfehlen, auf die entsprechenden Turnierstufen auszuweichen bzw. den Level-Fix zu verwenden. |
