Convert "i4" dump files to Amstrad DSK

https://gist.github.com/1310270 Source of a Java program to convert dtc -i4 dumps to DSK images usable in Amstrad CPC emulators. This is a basic implementation and can only cope with single sided, 40 track dumps of AMSDOS 3" disks in DATA or SYSTEM format. However that should be enough to recover n...

Re: Missing Index Error

OK, so are the DTC output formats documented anywhere? Apart from STREAM.

[edit]
Never mind - I figured out -i4 and made some CPC DSK images from the dumps :)

Re: Missing Index Error

I'm fairly sure I could write a MFM->DSK converter for standard formats. I've done MFM decoders before, and DSK converters, just never both in the same program :) Just need the MFM sector and data interleave layout information...

IPF support is nice. Pity I can't find any CPC IPFs ;)

Re: Missing Index Error

Belt replaced - the old one had degraded so badly it had melted to the drive wheels and had to be scraped off with the end of a screwdriver! I've now managed to create dtc -i4 MFM images of a few 3" AMSDOS disks, which is nice, but fairly useless unless I can use them in emulators. Is there any spec...

Re: Missing Index Error

I was able to image an AmigaDOS disk in a 3.5" floppy (dtc -i5) using the same cable, so it looks like the FDI-1 isn't working. I've ordered a replacement belt off eBay...

Re: Missing Index Error

I've just received a KryoFlux (Rev D) and hooked it up to an Amstrad 3" FDI-1 drive. The drive calibrates (-c2) all right, but I'm getting the "missing index" error reported on this thread when I attempt to dump a disk. C:\kryoflux_2.0b3_windows\dtc>dtc -i4 -ftest.mfm -l15 00009ab4: status=0 00009ac...
