Each standalone profile records where its version is read: the source at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package), or, where no reading can be made, kind unverified with the reason: a host the tools cannot read, a forge gone or not answering, no build recorded as read, a pin on another branch. Those keep their value, unconfirmed.

Cxbx-Reloaded derivative built for the Chihiro light gun games, used by
|
|
RetroBat as its "chihiro-gun" emulator from emulators\chihiro-ds and paired
|
|
with DemulShooter. No source is published. The build read here is the one
|
|
RetroBat installs, chihiro-ds.7z sha256
|
|
d20a9ffc6822c719f25d9b46c66249bf7efc9729cfddd10bda4f8629c96d48a5, whose
|
|
binaries carry "Chihiro-DS 1.0 (Mar 14 2025)". cxbxr-ldr.exe md5
|
|
d3675f7bb270072f33d9106497dd9bbc is the print DemulShooter lists for
|
|
"Chihiro-DS 1.0". cxbxr-emu.dll (md5 62f492f14b2af4bef7329ef269355a78) is

Every file name, path and error message in cxbxr-emu.dll that concerns a
|
|
file matches Cxbx-Reloaded develop with CHIHIRO_WORK enabled, as it stood
|
|
between CI-6f32d89 (6f32d89545cf0ad5a7d44ecedaf963005d7f84dc, December
|
|
2024) and CI-ec9934a (April 2025), which agree on every file loading path. That source is cited below with the CI-6f32d89
|
|
prefix as the reading of the logic the strings belong to. The only file the
|
|
fork adds is wm2_loader.dll.
|
|
|
|
Every path below is relative to the data directory. RetroBat's settings.ini
|
|
template sets DataStorageToggle to 1, the folder holding cxbx.exe. EmuDisk
|
|
and EmuMu are created there at startup, and the Chihiro files live in
|
|
EmuDisk\Chihiro (this build predates the EmuMediaBoard folder).

A title is Chihiro when its XBE type says so or a boot.id sits beside it.
|
|
Launched directly, such a title needs the media board ROM: a missing file,
|
|
an unreadable one or one that is not 2 MB ends the run. When either SEGABOOT
|
|
file is missing both are rewritten from the two 1 MB halves of the ROM, then
|
|
SEGABOOT_MBROM1.XBE is launched and boots the title. boot.id is read again by
|
|
the media board for the region flags, and its absence ends the run.

|
|
The four JVS base board images are memory mapped read/write when the
|
|
system is Chihiro. Byte 0x1F00 of the QC firmware holds the board region and
|
|
is rewritten in place to one the title's boot.id accepts, which is why the
|
|
copy RetroBat ships differs from the dump by that byte.

The package ships every file below except xboxdash.xbe and keys.bin. It
|
|
also carries chihiro_xbox_bios.bin, ver1305.bin, 315-6215.bin,
|
|
sp5001.bin, sp5001-b.bin and sp5002-a.bin in EmuDisk\chihiro, plus a
|
|
"chihiro (old)" copy of the folder. No string in the binaries names any of
|
|
them and nothing opens them.
