Every cited block was read again at HEAD: no ref left to review, no file name or hash literal added to a cited file since the pin (--detect-new-files --watch-hashes), refs recaled with their pins. Profiles built by a platform at a fixed commit, or whose bump would leave prose under an older pin, stay where they were.

Open-source reimplementation of Impressions Games' Caesar III engine.
|
|
It reads every graphic, text, sound and scenario from an installed copy
|
|
of the game. Nothing is bundled.
|
|
|
|
The data directory is the command-line argument. pre_init() makes it
|
|
the base path and runs game_pre_init(). A missing directory shows
|
|
"Julius requires the original files from Caesar 3" and exits
|
|
(ref: src/platform/julius.c:494-507, 586-592). File lookups are
|
|
case-corrected inside that directory.
|
|
|
|
Startup loads, in order, the text and message files c3.eng and
|
|
c3_mm.eng (c3.rus and c3_mm.rus as the alternative pair)
|
|
(ref: src/game/game.c:48-63, src/core/lang.c:142-166), the central
|
|
climate graphics c3.sg2 and c3.555, the barbarian enemy graphics
|
|
goths.sg2 and goths.555, and c3_model.txt (ref: src/game/game.c:79-104).
|
|
Any of them missing aborts init. The_empire.555 is loaded with the
|
|
climate graphics. A wrong size is logged and the game continues
|
|
(ref: src/core/image.c:283-293, 323). The other climates, enemies,
|
|
sounds, videos and scenario maps are opened from the same directory on
|
|
demand.
|
|
|
|
Recalbox lists Caesar III under roms/ports/Caesar3 with c3.exe as the
|
|
entry and patches config and save paths into /recalbox/share.
