The pilot's profile¶

profile.bin in the game's folder holds the pilot's profile: the 0xD0 bytes the game keeps at profile (0x00562CF8), written as they lie in memory, little-endian (profile_save, 0x004753F0). Its fields are those at the start of a saved game's MISS record, without the multiplayer deaths (Saved games).

Offset	Size	Holds
`0x00`	4	The mission the campaign had moved on to when a mission's end last copied the campaign in (`mission_number`); 0 in a new profile
`0x04`	32	The pilot's call sign, up to its terminator
`0x24`	4	The pilot's rank, 0 to 8 (`pilot_rank`)
`0x28`	4	The campaign's tier (`campaign_tier`)
`0x2C`	4	The pilot's kills over the campaign (`skull_count`)
`0x30`	6 × 4	The pilot's medals, 1 where awarded (`pilot_medals`)
`0x48`	6 × 4	The pilot's ribbons, 1 where awarded (`pilot_ribbons`)
`0x60`	28 × 2	Each mission's rating, by its number less one, -1 for none (`mission_ratings`)
`0x98`	28 × 2	The pilot's kills in each mission, by its number, missions 0 to 27 (`mission_kills`)

resource.hog holds a profile.bin too, which the game never reads: it opens the one in its folder (Hog archives).

When the game reads and writes it¶

campaign_new reads it (profile_load, 0x00475390) as the game starts, as the main menu opens and as START GAME begins a campaign, and the pilot takes its call sign. Where the game's folder has none, it makes a new one named PLAYER (string 0xBF), with no mission rated and the rest 0, and writes it; the call sign then stays as it was.
The game copies the call sign into the profile and writes it as the pilot roster's call sign changes, as the Reliant's rooms open, and last in each mission's start.
Each mission's end that moves the campaign on to the next mission copies the campaign into the profile after the autosave, and writes it (mission_end_record, 0x00475C2D). The last mission, which leads to the story's end, leaves it as it was.
Before a campaign mission of a network game, WinMain reads it and puts the pilot's rank, tier, kills, medals, ribbons, ratings and each mission's kills back into the campaign (0x004A99CC). The multiplayer screens write it with the call sign too.

In OpenReliant¶

game/gameflow.zig holds the profile (Profile), and reads and writes the file whatever the case of its name (ProfileFile). The pilot roster, the rooms, each mission's start and each mission's end write it as the game does.

Improvement: OpenReliant writes the file only where the profile has changed since it was last read or written. The game writes it again in each pass of the pilot roster while the pointer's button is held anywhere off the call sign.
Improvement: the game writes the file over the old one, so a write cut short leaves it broken. OpenReliant writes a new file, flushed to the disk, which then takes the old one's place in one step (files.writeAtomic).
Fix: the call sign the profile gives ends with its 32 bytes, where the game copies the name up to its terminator wherever that lies.

Not ported: a network game's campaign mission, which reads the profile back (#804).
