Re: Dumping and Emulation Issue

ScreenShotTrack39.jpg That's just because the sector header has been altered to tell you the sector is 1024 bytes while the actual sector itself is still just 512 bytes. HxC tries to interpret it according to the header information and makes it look like the next sector is inside it, which also cau...

Re: 5.25 floppies image profile

Thanks for the stream ! In fact you have dumped a 300 RPM disk with a 360 RPM drive. The bitrate in this dump is not very standard. In such situation set the "FLUXSTREAM_RPMFIX" variable/parameter to "360TO300RPM" : # # FLUXSTREAM_RPMFIX - Change the stream replay speed. # # NONE...

Re: Error writing Kryoflux stream

hi I just compiled the newest version of HxC. And wanted to write an STX file to disk. Well, hxcfe does not work. I help myself by first converting to ST and then to RAW (is usually fine if there is no fancy copy protection) This can happen when you use a dev/work-in-progress version. :D Anyway thi...

Re: Howdo I dump emax 1 disks to sdcard?

I recently purchased a kryoflux and have successfully backed up my E-Mu SP1200 disks to sdcard for use with my HxC floppy emulator. It works great. I am interested in doing the same with my Emax 1 disks. I don't know how to configure the kryoflux GUI to generate a viable image. Any Ideas? If you wa...

Re: Help with preservation of arcade system

Track 79, side 1, sector 205 is also 512 bytes, but it only has default formatting values. Not sure about this one. Here it appears as a 1024 bytes sector with a 512bytes size ID as the others sectors. Data CRC is E5E5 (the default format data value), no visible write splice at the 512 Byte data pa...

Re: Two beginners questions!

Pure speculation, but this is maybe a write precompensation issue. The converted raw timings are not modified (yet) with the write precomp. Is the HxC disk analyser showing you the same thing (Track view button-> Disk view) I presume that the KF DTC doesn't pass the stream to a write precomp circuit...

Shouldn't be a problem.
Which FDC is used ?

Re: IMSAI 8080 shugart 8" SSSD CP/M floppies

Ok got the second stream archive. Here is some analysis done with the bitrate.txt tweak : http://hxc2001.com/disks_analysis/IMSA14_22/2d/ the afi files can be converted to IMD/IMG. http://hxc2001.com/disks_analysis/IMSA14_22/2d/IMSAI14B_track00.0_raw_afi_small.jpg http://hxc2001.com/disks_analysis/I...

Re: IMSAI 8080 shugart 8" SSSD CP/M floppies

The second is your non-original IMSAI CP/M 1.4 disk as read by your NEC drive. As you can see everything is squished. Since there is no way to override the bit rates in HxC, its sampling algorithms "overload" and mark most of the sectors as bad. A normal floppy drive will also be mostly u...
