The profiles written for RetroBat and RetroPie were checked the same way: UZDoom, LZDoom, SRB2 and AdvanceMAME data ship with their releases, RetroPie installs the shareware Doom, Quake III and Wolfenstein data, the Aleph One scenarios and 4DOS beside the ports it builds, RetroBat installs Jynx's ROMs, and Recalbox's uae4all core comes without the AROS ROMs.

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.
