Oric HIRES screen format refers to certain files containing graphics for the Oric 8-bit home computer system. The Oric's HIRES screen mode is 240×200 pixels, 8 colors.

[edit] 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.
[edit] 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).
[edit] 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.
See also TAP (Oric)#Identification.
[edit] Software
- XnView - Supports TAP and raw format. Raw files must have an extension of ".hir".
- RECOIL - Supports raw format (.hrs or .hir). (It's unclear if it supports TAP.)
- PictConv
- img2oric (write-only)
