	[[Opponent Blaster]], a [[~~Mark Nailwood~~]] program, allows for edition of sped parameter from Stunts 1.0 opp?.res files. The program can't open compressed opp?.pre files from 1.1 without prior unpacking with [[stunpack]]. Even after unpacking, the addition of the banked corner parameter and the reordering of the resource list in the 1.1 files means Opponent Blaster is unable to parse them correctly. In fact, it turns out that 1.0 and 1.1 opponent data files are not interchangeable at all.

	Win/lose animations are made from individual bitmaps in ''opp?win.pvs'' or ''opp?lose.pvs''. The bitmap resources are named '''op01''' to '''op08''' - the actual number of frames within a file varies from 3 to 8. The animations are controlled through simple, unstructured resources in '''opp?.pre''' named '''winn''' and '''lose'''. Each byte in these resources is a numerical index to the op01 ... op08 bitmaps, and the overall sequence is the succession of frames.

Data corresponding to the Stunts [[opponents]] is stored by a number of [[Resource file format|resource files]], namely sdosel.pvs and the multiple opp?win.pvs, opp?lose.pvs and opp?.pre. As denoted by their extensions, the opp?.pre files store control parameters and text data, while the .pvs files contain bitmaps. A vanilla installation of Stunts 1.1 uses compressed opp?.pre files, while Stunts 1.0 has them uncompressed, as opp?.res. The contents of each file will be described below, organized by function of the resources.

==Opponent selection==

All the images used for composing the opponent selection menu are within ''sdosel.pvs''. Bitmap resources '''opp0''' to '''opp6''' are opponent portraits (opp0 is actually the chronometer for the time trial option); '''scrn''' and the auxiliary overlay '''clip''' form the background. Text for the opponent profiles is sourced from text resources in the ''opp?.pre'' (there are six of these, one for each opponent).

Win/lose animations are made from individual bitmaps in ''opp?win.pvs'' or ''opp?lose.pvs''. The bitmap resources are named '''op01''' to '''op08''' - the actual number of frames within a file varies from 3 to 8.

Each byte in these resources is a numerical index to the op01 ... op08 bitmaps, and the overall sequence is the succession of frames.

==Opponent performance==

{{sectstub}}

The primary adjustable parameters which determine opponent skills are maximum speeds for different track elements. These parameters are in an unstructured resource within ''opp?.pre'' called '''sped'''. sped is 15 bytes long for Stunts 1.0 and 16 bytes long for 1.1 . Each byte corresponds to the speed in mph for a track element, as described below:

{| class="wikitable"
|-
! Byte (in 1.1) !! Track element !! Observations
|-
| 1 - 3 || paved, dirt and icy road || respectively
|-
| 4 - 6 || paved, dirt and icy small corner || respectively
|-
| 7 - 9 || paved, dirt and icy large corner || respectively
|-
| 10 || banked corner || ''absent in 1.0''

[[Opponent Blaster]], a [[Mark Nailwood]] program, allows for edition of sped parameter from Stunts 1.0 opp?.res files. The program can't open compressed opp?.pre files from 1.1 without prior unpacking with [[stunpack]]. Even after unpacking, the addition of the banked corner parameter and the reordering of the resource list in the 1.1 files means Opponent Blaster is unable to parse them correctly. In fact, it turns out that 1.0 and 1.1 opponent data files are not interchangeable at all.

In addition to sped, opp?.pre also contains '''path''', a much larger (186 bytes) numerical data resource which function is not yet understood.
