Release id #194046 : 1541 Speed Test
Regarding the alignment, would you elaborate your thoughts on the following: (from the docs)
Quote:F3 align the head to track 42 in a better way than other programs do.
F5 moves the head to track 1
How to correctly align a drive:
1) gently unscrew the screws of the track 1 "stop"
2) press F3
3) press F5
4) gently move the track 1 block so there is 0.25 mm (a hair or little more) between the block and the head the head.
5) screw the screws tight carefully checking the block is still at 0.25mm from the head.

Considering this is the thread about your application - can you point to the post in question? That would be really interesting! |

If anyone downloaded it yesterday from github, please redownload.
Today's version is perfect but the version I uploaded yesterday had an error in the manual track change routine introduced by a feature I added.
The new version also allows to do the track 1 bump by pressing "b" key. (requested by a user)
The configure program in the D64 was also updated with one more customization.
The customize program allows also to disable the automatic loader and force the program to load itself always on drive #8. This feature was requested so it could be more compatible in some situations. |

Update:
Thanks to Groepaz who recently modified VICE (r38422) giving a bigger (way too big) speed range to the 1541 emulation,
now my program is not only the most accurate but the only one (or one of the very few) that supports drives at very high or very low speed settings. And STILL keeping maximum accuracy!
Go download the latest version as usual at: https://github.com/Zibri/C64-1541-Speed-Test
All major formats are available, PRG, D64, TAP and even WAV.
Note: in the D64 is also present a configuration program (CONFIGURE.PRG) that creates a customized version.
Regards,

>>>Voting down to 3 my program becase you don't "like me" is a very coward and childish act.
>>>Remove your vote if you don't like but ruining the program reputation because you feel mad is a bullshit.
>>>Grow up and do the right thing before I will tell everybody what an asshole you are.
Oh no, Zibri. Since you're too cowardly to read your messages, I'll post it here: You won't be telling anyone how to vote for what, not me, not anyone. Who do you think you are exactly? You're in no position to tell anyone what to do. You'll never be in any position to tell anyone what to do. You've bothered the wrong person with your ranting and raving. I'm not easily intimidated by lamers such as yourself. Pull your head out of your ass and don't bother me again, lamer. :) |

To be exact, that range was tested and verified with a real drive, its only slightly more than the extremes that could be observed (~266 to ~336). The previous range was totally arbitrary, invented by compyx for the UI. |

Oh.. so you show yourself!
Go back to your lair.
There's no food for you here.
Lamer? 8 million people think otherwise.
WTF you think you are? Just a loser downvoter.
I don't care about ranking at all.
It makes me just laugh there is people so "little" around. |

That's ok... I found a drive that could go down to 261 until now but never as up as 328... but I think is a good margin and it's finally symmetric.
It also gave me the chance to add 2 lines of code and correct the formula to support the lower speeds which I wanted to do from some time.
Thanks again, really. |

without I open a ticket, check the VICE code about the "Wobbling".
As it is is totally unreal.
Even at the maximum setting it does not resemble any 1541 I have seen so far.
Test my program with a real drive and with VICE and you will see clearly the difference.
Also check the video of the tutorial of my program where a guy (his 10 year old son!) sets the speed of a 1541 using my program. In that video you can clearly see the wobbling of a real 1541.
As of now I use the wobbling set to 0 when testing calculations and to maximum.. but the algo must sure be rewritten.
A hint: you could add to the "speed variable" a sinusoid multiplied by some random number in the "range" of the wobbling variable.
That should give you more real looking results.
It's very easy to spot an emulator otherwise. |

Quoting ZibriIt's very easy to spot an emulator otherwise. The entire VICE staff themselves are the first to "admit" that some things remain to be emulated correctly, and as such may serve as low-hanging fruit for emulator detection. (There's also a public test result matrix where no emulator passes each and every test, iirc.)
That said, if this is such an important thing for you, why not submit a patch yourself? :) |
