This firmware is quite old... Anyway about the Gotek- HxC all is there (files + updates) : https://hxc2001.com/download/floppy_drive_emulator/HXCFEUSB_HFE_beta_firmware.zip https://hxc2001.com/download/floppy_drive_emulator/index.html#stm32hxc https://hxc2001.com/store/ @jedimatt42 : Conversion to HFE is not needed anymore with the hxc firmware.

With the HxC firmware you can use both in read & write mode.

I have fixed the KF Stream loader. this one was broken since a month. The dump is fine : But the bitrate is not quite 250000. 7.6us instead of 8us. And the lower part at 4us show something that look like an write compensation effect. unless the flux reversals on the disk are migrating...

And this is the same software used by arcadeshopper ?

Well in this case still only 2 solutions to understand the problem : - Raw Kryoflux stream files. or - an oscilloscope on the Write Data & Write Gate lines...

no, what i ask is : have you already tried to write files with this controller and the "lotharek" emulator on HD images ?

According to the documentation it seems possible to change the write precompensation, at least for the hard disk. not sure for the floppy...

Here are the HDC9234 write pre-compensation possibilities : If it is set at 600ns or 500ns during HD formating the flux capture will probably fail... I can tweak the capture routines to make it work but i don't have this FDC here to test the modifications. BTW is normal writing working fine on HD disk with this controller ?

Thanks. i don't see the schematic in this pdf. I see 2 possibilities : - The FDC write-precompensation setting is quite aggressive which make the pulses capture not working properly. Is there a way to change this parameter ? Or - The emulator is forced at 250kb/s (can be forced in the internal menu...)

Thanks. Everything look fine. So unless there is no flux coming from the FDC the image should be at least altered... You are formatting in HD mode ? EDIT : It is altered and it is similar to the BeeryMiller image. Is there a schematic of the HFDC available somewhere ?

Then this is becoming odder : The image is not altered at all. Look like nothing was written to the image. Did you saw "WA" on the lcd during the formatting ?

The image look fine. i suppose that this is not the one coming from your sdcard/usb stick after the failure ?

Yes me too. No HD images in the link pointed by acadiel.

Please share the failed HFE file.

they look fine but please note that there is no HD images in this images.
