|
|
XRick is an open-source reimplementation of the Rick Dangerous engine (Core Design, 1989),
|
|
ported to libretro. It is not a general-purpose emulator; it only plays Rick Dangerous.
|
|
|
|
The core sets need_fullpath = true, valid_extensions = "*|zip", and supports launching
|
|
without content (RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME = true, libretro-core.c:93-97).
|
|
|
|
Game data handling works in two modes (retro_load_game, libretro-core.c:312-360):
|
|
1. Content provided: the content path is passed directly as the -data argument
|
|
(line 318: snprintf "xrick" "-data" "%s"). Content can be data.zip or a directory.
|
|
2. No content (standalone): the core builds the path {system_dir}/xrick/data.zip
|
|
using fill_pathname_join_special_ext(RETRO_DIR, "xrick", "data", ".zip") at lines
|
|
324-326. If this file is missing, a "game files missing" error is displayed (line 337)
|
|
and loading fails.
|
|
|
|
The fallback data path at line 359 confirms the expected location:
|
|
snprintf(RPATH, ... "xrick" "-data" "%s/xrick/data.zip", RETRO_DIR)
|
|
|
|
All game graphics, maps, tile data, entity tables, and screen layouts are compiled directly
|
|
into the binary from dat_*.c source files (dat_ents.c, dat_maps.c, dat_picsPC.c,
|
|
dat_picsST.c, dat_screens.c, dat_snd.c, dat_spritesPC.c, dat_spritesST.c, dat_tilesPC.c,
|
|
dat_tilesST.c). Only the sound files are external.
|
|
|
|
data.zip contains 29 WAV files in a sounds/ subdirectory: sound effects (bombshht, bonus,
|
|
box, bullet, crawl, die, ent0-ent8, explode, gameover, jump, pad, sbonus1, sbonus2, stick,
|
|
walk) and music tracks (tune0 through tune5). The data.c module handles opening files from
|
|
either a .zip archive (via unzip.c) or a flat directory, selected by extension detection
|
|
(data.c:56-73).
|
|
|
|
xrick.c:23 shows the hardcoded fallback: data_setpath("data.zip") when no -data argument
|
|
is provided.
|
|
|
|
system_dir is obtained via RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY (libretro-core.c:185-189),
|
|
falling back to "." if unavailable.
|
|
|
|
The data.zip file ships in the xrick-libretro repository root and is the original xrick
|
|
0.21212 game data release from 2002 by BigOrno.
