Releases Not Working On Ultimate64
Yesterday, it was reported to me that Sir Arthur Pendragon Quadrilogy is not working on the Ultimate64 V1.2. You can load every game, but pressing fire to start does nothing. I checked with V1.1, and the same.
It is not a release problem, but a U64 problem. The original game also has this behavior. I assume all other cracks too.
The issue has been reported to Gideon.
I thought we can collect similar issues for other games/demos here. |

i am running the VICE testsuite right now. its so broken, reporting individual programs/releases doesnt make sense at this point, IMHO. |

Does it at least emulate all illegal opcodes correctly now? :)
The 6510 emulation core is most probably inherited from 1541U's 6502 core, so... |

strangely enough, no it doesnt. a bunch of opcodes are broken now that worked on the 1541U >_< |

You're probably the first to have run the vice test suite on the U64, Groepaz? ;-) |

Quoting Knight RiderYesterday, it was reported to me that Sir Arthur Pendragon Quadrilogy is not working on the Ultimate64 V1.2.
I am not sure why they would report this to you, since it's clearly a U64 issue (and they know it). Silly retro lamers, I guess :) |

As people already said: Complaining to you is meaningless; ask them to contact Gideon, as this is not an issue with stuff that works on real hw.
Me and some pals gather every U64 bugged demo we see in a huge list, that we later will send to Gideon when we are tired of testing stuff. Hopefully that list will help him fix the Ultimate. But perhaps it's meaningless as stated by Groepaz. |

at this point i'd say it is - it'll be a LOT more work to debug those demos and try finding out wtf is wrong with them than just go through the testbench and fix things :) (i have done this a couple times in the past for chameleon - demos and games are terrible testcases) |

That how many of the test programs came about. Once the reason for an anomaly in a demo was found a test program was written to explore all corner cases around that anomaly.
It's going to take a while to make the implementation pass those test cases if they weren't considered while designing. Well, I guess that is test driven development for you, only not doing it properly makes it much harder when you have the very long "compile"/test cycles of an FPGA. |

actually i knocked up the whole script driven testing just for that (chameleon) :) |

That's what I figured.
As you have run some tests, any specific areas where the U64 needs the most improvement? |

i'd start with fixing all the broken opcodes, no point in even looking at the rest when CPU is broken :) (but not done yet... it will take a couple of days to run all the tests by hand)
[disclaimer: you still have to run those tests. i am not in the position to publish detailed results right now] |

Ouch, if the cpu is broken in any major way all bets are of I guess. Undocumented ops and decimal mode isn't required for most of the tests though.
I don't have access to an U64 so I'm mostly just curious at this point. :) |

couple undocs... however, the impact is probably quite noticable in both original games and demos (not so much in the test programs) |

Forgive my ignorance but: Is this thing open or closed source? |

I received feedback that this also has issues with U64:

No. U64 has issues with that game. Not the other way around. ;) |

Yes. Please do not "fix" stuff to work in updateable emulators. Otherwise less incentive to fix those broken emulators. :) |

Let me spell it out.
> Please do not "fix" stuff to work in updateable emulators.
> updateable emulators
> updateable
Which the older 1541U1 are not, effectively, as they aren't officially supported any more and superseded by 1541U2, which is another piece of hardware. |

lame excuses (and they ARE updateable. just noone cares to do so. guess why) |
