100 emulator names the two platforms run had no profile, so their packs carried nothing for them. Each was read from the platform's own launcher or scriptmodule: the same program as an existing profile takes the name in cores:, a different build gets its own profile read from that version, a launcher or self-contained game goes to remove_cores, and the rest are new profiles written from their source or shipped binary. The files they need that the collection lacked are collected from the upstream distributions. Bungie and splitwolf trees are read by path and stay out of dedup.

|
Native port of the Jak and Daxter games built from the decompiled GOAL
|
|
code. gk runs the game, goalc compiles GOAL source, and extractor turns the
|
|
user's PS2 ISO into the data gk loads.
|
|
|
|
RetroBat installs v0.3.8: the gk.exe, goalc.exe and extractor.exe of its
|
|
opengoal.7z are byte identical to opengoal-windows-v0.3.8.zip, and its data
|
|
tree has the same files, so the profile is pinned to that tag. The
|
|
launcher reads the game name (jak1, jak2 or jak3) from the first line of
|
|
the ROM file, then checks data/out/<game>/iso. When that folder is missing
|
|
it runs "extractor.exe -g <game> -e -d -c <iso>" with the ISO path set in
|
|
the system options, and refuses to start without one. It then starts
|
|
gk.exe -g <game> with its own config folder.
|
|
|
|
extractor (decompiler/extractor/main.cpp):
|
|
1. -e takes a file whose extension is .iso and which is larger than
|
|
1000000000 bytes, unpacks it into iso_data/_temp and computes an XXH64
|
|
over the hashes of all its files (decompiler/extractor/extractor_util.cpp:278-304,
|
|
decompiler/extractor/main.cpp:295-317).
|
|
2. validate needs a DGO folder in the extraction. It reads the serial
|
|
from the boot ELF name (SCUS_971.24 gives SCUS-97124) and hashes that
|
|
ELF with XXH64, then looks both up in extractor_iso_database
|
|
(decompiler/extractor/main.cpp:35-110, decompiler/extractor/extractor_util.cpp:30-166, 229-251). A missing DGO
|
|
folder stops extraction. Any other mismatch only fails the run under
|
|
-v, which RetroBat does not pass, and leaves the data in
|
|
iso_data/_temp instead of iso_data/<game> (decompiler/extractor/main.cpp:318-335).
|
|
3. -d decompiles with the config of the detected release, -c compiles
|
|
goal_src into data/out/<game>.
|
|
|
|
The database knows Jak 1 as SCUS-97124 (Black Label and Greatest Hits),
|
|
SCES-50361, SCPS-15021 and SCPS-56003, Jak 2 as SCUS-97265, SCES-51608,
|
|
SCPS-15057 and SCKA-20010, and Jak 3 as SCUS-97330, SCUS-97516,
|
|
SCKA-20040 and SCES-52460. The contents hashes it stores are XXH64
|
|
values over per file hashes, not hashes of the ISO file, so no entry
|
|
below carries one.
|
|
|
|
At run time gk reads only what the extractor and compiler built:
|
|
out/<game>/iso, listed by the fake ISO file system, and out/<game>/fr3
|
|
for the renderer (game/overlord/common/fake_iso.cpp:57-71,
|
|
game/graphics/pipelines/opengl.cpp:90). The data folder of the release
|
|
(goal_src, decompiler/config, custom_assets, game/assets, launcher) is
|
|
program source and configuration the compiler reads, shipped with every
|
|
build. goal_src/jakx is present, but the extractor accepts only jak1, jak2
|
|
and jak3 at this tag (decompiler/extractor/main.cpp:16-18, 289-292).
