Yes, it is a problem... Usually can be determined by file size. As I
said, PC99 stores tracks, including the control information not
normally present in a sector dump. V9T9 stores sector dumps.

Do you need specs for these particular formats, given they are sector
dumps (with PC99 throwing in control information), or do you need the
TI file specifications themselves?

PC99 is a commercial emulator, and may be hard to find documentation
for, although it does appear to be supported by others.

On ftp.whtech.com, under pc utilities, look for ti99-pc. This is a PC
program written in Qbasic with links to assembly code that basically
converts between TI disks and the PC99 or V9T9 formats - and has an
intermediate format (called TI99-PC disk image file) which is
basically a raw sector dump, if memory serves. This program has
excellent on-line help that may tell you all you need to know... more
than likely it will tell you more than you care to know.
