Naturally, the amount of sync I need to add amounts to 4 bits. Is there a way to add a nibble of sync to a G64 image? Would it require adding a $F0 to the end of the existing sync and then bit shifting the rest of the track back into those lower four bits? If so, is there a G64 editor out there to make this easier? My hex editor doesn't really do this properly. : : Is it possible to use speed zones in the G64 image to alter the read speed of the sync marks? I tried this, but either I edited the wrong bytes (modifying these files by hand is a real pain), or it just plain doesn't work. : -- Just add it to the beginning - i.e. change the last byte before the sync to $5f or something (or change according to what is already there, this data is almost always expendable). I don't think any emulator knows about speed zones- they can't interpret the byte-aligned data given to them with a different density. |
