|
|
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).
