So, as a recap - single sided disks use the bottom head only and so there should be 40 entries (for 40 tracks) or 80 entries (for 80 tracks) that use TDH entries 0,2,4,6, etc. It's just there to make it easy for whatever is looking at the data to display the number of heads used. So, I don't really need to know how many heads were actually used in the image via the HEAD byte (0x0A). I know if an entry contains 0x00000000 then there is no data for that head (top or bottom). In my software I don't look at anything except the TDH entries.

I am not sure if I made this very clear, so I have revised the specification. When imaging a double-sided disk (like Amiga, IBM 1.44MB, Atari ST, etc.) this is automatic. There's not likely to be too many images with just the top head, but it's there for completeness. You should also be setting the HEAD byte (0x0A) to 1 (not 0 or 2) in these cases to indicate a single bottom head.

Even TDH entries are the bottom head, and odd TDH entries are the top head. scp specification, with a single sided image you should be skipping every other TDH entry. The HxC conversion for a 40 track single-sided image comes out as 20 tracks (2 heads), and a 80 track single-sided image comes out as 40 tracks (2 heads). I had a bunch of people recently trying to convert. > General : Lots of code fixes and improvements ! > Linux build : Automatic FLTK package download and preparation.įLTK build : Use the fltk automatic flags to match with your graphic stack. > FLTK updated to v1.3.5 for all platforms. > Game Doctor SF3 / SF7 file support added. > New files Support : Kurzweil K25 (K2500) and K26 (K2600) file support. > SCP loader : Fix/set the number of heads to 2 when the number of head(s) field is set to 0.
