Re: KryoFlux stopped working

What's the response you get after running the c2 calibration test?

Sounds a bit like something wrong with the stepper motor. Do you have other drives to test with or a way to test the drive in some old computer?

Hopefully the parameters are correct as some of the samples show repeated data and there's incomplete data on the disk which is not on the directory. Then again I don't know how the original hardware works if something gets overwritten.

Re: Please Help Again re Weak Bits

If you open the G64 file in a hexeditor and go to offset 0x1116 you should see bytes D5 AA 33 86 30 AA D4, and you only need to replace the 33 86 30 with 00 00 00. Few consecutive 00-bytes in a G64 is a way to tell emulators that this part of the track should generate random data when read. DTC also...

Re: Are there any 5.25'' floppy drives that are officially supported and which can read "flippy disks"?

Panasonic JU-475-3/4/5 models Newtronics D509V2/3/5 models Teac FD-55GFR Of those three drives, which would you say is the most reliable? Panasonic usually is good with C64 floppies. Newtronics maybe has a somewhat loose mechanism and might have better chance at reading scratched disks. Teac has la...

Re: What kind of copyright does the 1991 Lemmings disk use?

Lemmings uses extra sectors as protection. Disk has 9 sectors of data per track, but the first 5 tracks on both sides have 12 sectors. 10th extra sector is a shorter sector. 11th and 12th sectors have the sector headers next to each others so sector 12 is inside sector 11 and they also overlap the f...

Re: Imaging 100TPI 77 track Exidy Sorcerer disks on a Micropolis 100TPI

There's a good chance the disk is self-destructing if any more attempts to read it is made unless the disk is throughly cleaned (and the drive head too again). Best would be to cut open the disk, remove the platter and carfully wash it in warm soapy water while scrubbing it with your fingers and the...

Re: Casio FZ-10M Disks

On the voice- and bank-images the first 3072 bytes (0xC00 in hex) need to be removed and "maybe" the empty space from the end too, identifiable where you start to see lots of Z in ascii (0x5A hex). On the resulting voice-file you then need to edit the 00-bytes right before the sampledata a...

Re: Imaging 100TPI 77 track Exidy Sorcerer disks on a Micropolis 100TPI

DTC now detects some sectors from the first few tracks, but looking at the scatter plot everything turns into noise/nothingness very quickly.

So either something gets released from the surface contaminating the head or there's still more cleaning to do.

Re: Casio FZ-10M Disks

Awave adds few bytes to the fzb and fzv files for some reason, and without those bytes it doesn't recognise the files. Not really sure what the bytes mean but I managed to convert these so they can be loaded. BeginVce.zip BTAHDial2.zip FZ1Banks1.zip The FZ1Banks1 raw streamfiles went through some he...
