TAP format

HIRES files may be "raw", with no header, or they may use a profile of Oric's TAP (tape image) format as a container.

Format details

Attention is called to this "probable bug" in some versions of img2oric:

This may have resulted in some bad TAP graphics files in the wild (example).

Identification

Raw files are (usually?) 8000 bytes in size.

TAP graphics files start with a variable number of 0x16 bytes, then 0x24. The next 8 or 9 bytes can probably help identify the format; one possibility is 00 ff 80 00 bf 3f a0 00.
