c128 test help needed to improve c128 emulation
Hiya all,
I am in the process of improving the MMU emulation in the x128 of the VICE project in collaboration with the author of the Z64K emulator and I need more test results from real c128 hardware.
People who are able and willing to test, please take the mmuswap-??.prg files from
https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/c12..
When running the tests please make sure you do a hard reset / power cycles between tests.
When reporting the results I only need the test nr and the border color.
Thanks in advance to any-1 able and willing to test. |

If you happen to own a PAL C128DCR, like me, can I still be part of this? Or is it only for plain flat C128 owners? |

any kind of c128, the more different kinds the better, and the more results the better.
I appreciate all the help any-1 is able/willing to give. |

Thank you Hypnosis and any future testers.
Please stay tuned to this topic since there will be some changes to the tests as we get more results and I might ask for retests. |

for some of these test there will be no passed till I gather more information, so what I am interested in is not so much if it passed or not, but more the border color for each test. |

Oh, so I needed to test all files. My bad, I'm kinda slow. I'll test tomorrow with 128 & 128dcr. |

I have updated the tests 08, 14 and 16, for Tokra and Hypnosis, please re-test tests 08, 14 and 16 from the sf site.
For every-1 else please make sure you use the current tests.
Thanks. |

Also, can you clarify what constitutes a "hard reset"? I power-cycled my 128D each time on that run but if I'm going to make a habit out of this and can use the reset button instead, that might be nice. |

during the weekend I will put extra code into the tests that will make sure every test starts from the same initial conditions, and no power cycling will be needed anymore. |

thank you for all the test results.
I have 'fixed' test 16, and added tests 18, 19, 20 and 21.
So testers, please re-test 16, and test 18, 19, 20 and 21.
As before the passed/failed is currently not interesting, only the border colors matter for the results.
Thanx in advance. |

Something is wonky over at sourceforge. The page with the tests is gone. |

Thank you all so much for running these tests, they have helped to make x128 and z64k to be more accurate compared to the real hardware.
For almost all of the tests we have an agreement in the results, the only tests we have a disagreement in the results are tests 06, 20 and 21.
These tests check if when both the zero page and stack page are mapped to the same normal ram page where the back translation goes, that normal ram page will show either the zero page or the stack page, not a mixture of both.
For the people who got a 'white' result from tests 20 and 21, the results show that the stack page takes priority.
For the people who got a 'black' result from tests 20 and 21, the results show that the zero page takes priority.
To find out why there is this different I have one last request.
If you can, please find out what revision of the 8722 you have in your c128, sadly there is no way to tell register-wise so you'll need to look at the chip markings, from what I can find it will be either 8722R1 or 8722R2.
I'm hoping the zp/sp priority difference is tied to the revision of the mmu.
Thanks in advance to the testers who are willing to go through the extra trouble. |

(I'll open the flat if you really need but am not in a great rush to do so) |

My tested PAL C128DCR (HB1 005865) has a MOS 8722R2 4786 22.
And I am sure we love to help. :) This is interesting and fun. |

Do you still take more results at a later time? I have three c128s here but cannot check right now. |

Thank you all for the test results, we were able to learn a lot more from the results and have improved the emulation of x128 and Z64K.
The last part of this mmu testing adventure will be some z80 related tests, don't worry, you won't have to start cp/m or something, the test programs will switch to the z80, run the test and change the border color to indicate the result.
I will start making these tests on the weekend, since working life got in the way for now. |
