In cpc_flop.xml these and many sets show supported="no"> so I'd assume this behavior is already known? Will mark this as Direction Needed to get input from Developers. |

I've looked it just now and in that xml, all the entries show supported="no">, at least at 174 cpc_flop.xml...there are no sets with supported="yes", and most I've tried work fine. |

Updated the report with Bestial Warrior, another game from Zeus soft with the same problem than the others. |

This is caused by the change in I/O mode for port A of the PPI (connected to the PSG data bus). It selected PSG register 14 (port A, connected to the keyboard), but has to change PPI port A to input mode, which causes it to write 0xff, which in turn changes the selected PSG register to 15 (0x0f). Commenting out the callback call on mode change in i8255.cpp gets Hundra further, and makes Comando Tracer and Bestial Warrior fully playable. There should be a better way to achieve this, though. |

With the latest mame git all the games are now playable but Hundra, that gets stuck after the main menu. |

Should we close this report and open other for Hundra? Not sure if the black screen after the main menu is related to the PSG data bus... |

It wouldn't hurt to make a separate report for the non-functioning since what seems to be making it not function is not the same as the others. After which, we can resolve this one (less hundra) |

Resolved, moved Hundra to a separate report. |
