Krill loader not working
Hi There,
We are still strungling with the Krill loader, I have to say that we have progressed a lot but we get the following problem :
If we use the following command :
Make prg INSTALL=4000 RESIDENT=9000 zp=10
The install is working good at 4000 but the loader is still located at 0400. if we forced it to load at 9000 it ain't working.
Are we doing something wrong here ? |

Okay, obfuscation, i see. But as long no stepping happens by simply turning on and off the motor, no problem. Then no code is required to handle that, as doynax feared. |

Quoting KrillNo, i never noticed. The motor is turned off long after the stepper has settled, and switching off the current coil presumably would not move the head. That's comforting to hear. Probably means that there's enough inertia not to have to care much about it, especially not in demos.
Quoting KrillWhy track 35? Because you might end up in the woods (track 35.5) on a standard-format disk and wouldn't find your way out? Precisely. A loader which reads the tracks of the sectors flying by can adjust to unexpected movements as long as it stays in the formatted area, but drifting beyond the edge of the map would require harder (i.e. more RAM-consuming) to recover from.
Actually my old D64 loader couldn't do this but I imagine you'd need to be decoding the sector headers anyway for out-of-order reading to work. |

After we get the loader working in winvice 2.4 we tested it in winvice 2.2. it is also working good in winvice 2.2 so we tested it out on a real c64 and after the part is loaded and decrunched the part freezes.
What is the difference between winvice 2.x and a real c64 ? |

what exactly did you have to do to get it working? |

I got it working if I put all the files on a .d64 file and start the .d64 file.
If I compile the coding with kickassembler and start it with the .d64 file attached we have the same problem the the part what is loaded freezes after decrunching. |

if you attach a prg, true drive emulation is not active and prolly virtual device traps are on. always use d64 |

If i don't put all the files on a d64 :
I have a file which will be loaded put on a d64. I then have my sublime/kickassembler with coding. I start the compiled coding (1st part) from kickassembler so winvice is started. I have a keyboard check so i can first put drive emulation to on and attach the appropiate d64 file (2nd part) with attach drive. I then press the keyboard so the coding is executed further and the file should be loaded from the d64 disk.
But after the decrucnch the part starts and immediately freezes.
Now if I put the compiled coding (1st part) also to the d64 so I don't have to attach anything then winvice will start the first part, the second part is loaded and decrunched correctly so it starts all good but it won't run on a real C64. |

so does it load and decrunch on the real C64 too? if yes, then the problem isnt the loader at all |

chesoner, sounds like you were thinking that all required files magically would appear on the correct d64.
You just need to build the d64 correctly (using the vice cmdline tool c1541.exe for example).
also, save your vice settings so you always have true drive emu on, manually changing settings every time will bore you to death ;)
and do *not* use multiple attached devices if you use krill's default 2bitatn loader or it will not work at all. just 1 1541 attached, no more no less. |

It is only working in winvice 2.x, not on a real c64.
@burglar: The to be loaded file in on a d64 which is attached with the drive in winvice so all files needed is on the d64 file, i think.
Maybe we are doing something real stupid but we can't figure out what. |
