'''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.

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

== Format details ==
Attention is called to this "probable bug" in some versions of img2oric:
* http://caca.zoy.org/changeset/2847

This may have resulted in some bad TAP graphics files in the wild ([http://caca.zoy.org/raw-attachment/wiki/libpipi/oric/output.tap example]).

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

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

See also [[TAP (Oric)#Identification]].

== 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.)
