Formatting a disk from Basic
Anyone knows how to format a disk in basic, without using any cartridge-specific commands? IIRC it's something with "open". |

wanderer,
replacing files with original 1541 dos is bugges, I've experienced it on the real thing. if you really have to attach an AR, and that will do it fine.
Vice.. I've noticed that it doesnt handles files correctly when a new file is created on the attached .d64 ( PRG* it doesnt close the file until you deattch the d64). That was a year or more ago, not sure if this bug still exists, but when making a new file within vice I always deattach and reattach the d64 to make sure. |

@Wanderer: "I've had many bad experiences with the emulator lately". Hmmm... so you're basically saying that you're coding on the real thing, but on an emulator, that is, u're not cross-compiling. Ever considered simply use Save Snapshot in the VICE menu instead of fiddeling with disks etc?
I atleast always do that when I want to save f.e. a BASIC program or whatever. It's not until I wish to transfer the code to the real thing or distribute it as a .d64/.prg I actually save to disk. |

I use CCGS, which I've become accustomed to. It's a mess really.
I save my data files in the monitor but they can't be loaded from a .d64 file, only from the monitor (where they are stored in the CCGS root directory).
Then I have to import the data files using the D64 editor, link them, and I have the final product.
However with CCGS (which has an option to allow instant write on the D64 file so as not to keep it open) it still corrupts.
I have tried the snapshot option, and it works great... but I am somewhat convinced that it also snapshots the D64 file. I'm not 100% certain but I can recall a time where I loaded my snapshot and went to the disk directory to find an outdated file instead of the newer one.
I'd love it if I could save data files direct to D64 file so I could link them. I tried Vice once or twice and it works good but I'm not sure I can save direct to the disk file?? If so I may consider switching.
In a related/unrelated note, you have to be careful with the D64 editor and the "wipe" file option. I once "wiped" a SCR-atched file that was crosslinked with a real file. This occurs when you scratch a file and it's sectors become occupied with a valid file - d64 says they are crosslinked. If you WIPE the old file (which shows as SCRATCHED) so as to avoid getting that crosslink message it will actually fill in the sectors with 0 bytes. Ouch! Thus your valid file gets erased.

VICE only updates the D64-file if it's detached (IIRC there was a option to update the file after every write but I'm not sure...)
The old SAVE"@:XZY",8 mostly didn't work because the 1541-DOS first wrote the file and then scratched it afterwards, so when there were too less blocks left on the disc, the file went corrupt. |

with save"@:xxx" I had a problem when the new file was overwritten on an older existing one. So when loading "somefilealreadyondisksinceages" It loaded "filesavedwith@:" instead.... |

Hehe, only stupid Action Replay folks use @:, FC3 users can continue to work during file deleting :) |

They do? On small files the FC3 is actually faster than an AR6 due to less drive upload time and no full track access :P |

graham: guess what, @: is a commodore dos, and no AR only feature. hope it helped your mental health today, to call us stupid AR folks. |

Oswald: Yes, @ is a DOS command but you know what it does? It first saves the file to disk and then deletes the old file. |
