  1. Yes my English is bad. Next time I use Google Translator :] Sorry. I'm better at reading then writing. Point is it looked so bizarre to me that I thought it was board data. I was trying to understand why someone code this way.
  2. But he must wrote LDA zptable-$80,Y also he must know this will be absolute address.
  3. As far I understand `STA $FFFE,X` was unintentionally but if he thinks he was on ZP why he use Y register? `STA $FFFE,Y` must be intentionally codded then `STA $FFFE,X` can be too. Right?
  4. `STA $FFFE,X` why on Earth someone wants to lose cycle this way?
  5. @Wrathchild ah, right this is not contiguous block of code/memory you pasted.
  6. accidentally maybe this looks like a code or maybe some kind internal chess board representation in memory. https://www.chessprogramming.org/Board_Representation most popular at that time was: https://www.chessprogramming.org/10x12_Board
  7. Looks more like internal board representation or something :] I bet above is rather data then code.
  8. In old times programmers thinks that each doubling of the clock speed adds 50 ELO If CC4 have ~1650 ELO points on stock A8 then on your machine will be quite strong for amateur :]
  9. @drac030 CC4 its one of the best chess on A8 but CC4 is only one strong engine not working correctly with Rapidus and more MHz. Can you possibly patch this in any future? On Rapidus CC4 starts making illegal moves, spotted on Alitrra 3.90.
  10. This test was interesting Stockfish Vs CC4 Showed white time is irrelevant. Stockfish_vs_CC4_2R-for.mp4
  11. Funny... I played many times tournament games, CC4 never hangs on atari800 emulator, maybe it is real machine issue? I don't need this patch.
  12. @devwebcl never seen this one, not confirm.
  13. @devwebcl what kind of bug? http://www.atarimania.com/game-atari-400-800-xl-xe-colossus-chess-41_1137.html ? I played many hours with CC4 and don't spot any. https://atariage.com/forums/topic/142225-colossus-chess-41/?do=findComment&comment=1722746
  14. https://www.schach-computer.info/wiki/index.php/Mephisto_III-S_Glasgow google translate (to English) works well for me Mephisto III-S Glasgow runs on Motorola 68000 12 MHz Machine ELO list https://www.schach-computer.info/wiki/index.php/Wiki-Elo-Liste in comparison Colossus Chess 4.0 on A8 looks very well :] chess computer ratings 1993.txt One more interesting site I use https://www.chessprogramming.org/Colossus_Chess
