Interleaved File Copy
Hello Disk Wizards,
i am currently testing some irqloaders, and want to see how fast they can get with different interleaves.
The only tool I found is intcopy/taboo, but it is c64-native and seems to have problems with already allocated Blocks.
Any Ideas which Tools (preferable cross-development) I could use to write to a Disk while specifying the interleave ?
TIA,
Zed Yago
PS: All cross-development tools I checked write with interleave 1!!!

Speaking of xdev tools, I think Star Commander has configurable sector-interleave. |

But AFAIK because there's no batch processing or commandline operation (or they at least aren't documented), building images with SC at each interleave will be a royal pain :) Same for 64COPY. I wouldn't have made my own utilities if I knew a sane alternative :) |

In that case, prg2d64 would be even greater pain, Agent C. :) Anyway, Makedisk should do the job. |

Yes, but it is easy to modify & recompile for selectable interleave, unlike some filecopy utilities with no source.. In fact I'm doing this myself now & uploading updated tools. |

Wait, didn't Joe add a batch processing feature to SC in one of the latest beta? I don't know if the interleave can be controlled from the commandline, but at least some sort of batch-processing is there, I'm sure. |

Ah, there actually is a function to set a variable (which can control interleave) so I was wrong. Anyway, cool to see that SC keeps progressing..
Still, I'd wish c1541 from VICE would get ability to configure interleave. It's probably most versatile command line oriented disk image manipulator. |

If you need to change the interleave on the C64 (or emu)
before save, do the following:
open 1,8,15:print#1,"m-w"chr$(105)chr$(0)chr$(1)chr$(interleave):close1

Thanks for the various infos!
As I am currently in leisure Time without internet, i thought about the problem a little bit, and coded myself the desired tools :-)
If anybody is interested in copy2d64, or its analysis companions readts, writets and printbam, leave me a PM.
copy2d64 has commandline-options for interleave, rawmode(without loadaddress nor chaining), direction, use track18 and so on. It has even an option for specifying how long it takes to move the head one track further!
Seems to work, and dreamload and plushdos got a huge speed-improvement compared to interleave=1.
Happy new year 2003!

Heh.. Using the normal interleave 8 will also double the speed comparing to using 1 :). |

good that i coded several irq loaders whose speed is not affected by the interleave at all =) |
