pin_frozen was prose, and no tool read the build file it cites, so a platform building another revision left the profile holding one nobody ships. pin_build records the platform, its repository, the revision read, the file, the variable and its value. check_freshness reads the file again where the platform's YAML now stands and reports STALE when the value moved. 36 of the 46 held profiles carry it, each value read from the build file at the platform's scraped revision. The other ten name no build file and are counted on one row: six RetroBat binary packages and four holds not tied to a platform build.

|
notes: |
|
|
Dreamcast emulator descended from nullDC. The Linux build is compiled
|
|
for one platform, and the default is dreamcast, which sets the ROM prefix
|
|
dc_, a 2 MB boot ROM, a 128 KB flash and NVR_OPTIONAL 0
|
|
(ref: core/types.h:209-217).
|
|
|
|
LoadRomFiles() tries dc_boot.bin, dc_boot.bin.bin, dc_bios.bin and
|
|
dc_bios.bin.bin for the boot ROM, then dc_nvmem.bin, dc_flash_wb.bin,
|
|
dc_flash.bin and dc_flash.bin.bin for the flash
|
|
(ref: core/hw/holly/sb_mem.cpp:30-51). Each candidate is accepted
|
|
when a full chip's worth of bytes can be read from it
|
|
(ref: core/hw/flashrom/flashrom.h:39-49, 61-99). No hash is checked.
|
|
With NVR_OPTIONAL 0 a missing flash fails LoadRomFiles() the same way
|
|
a missing boot ROM does.
|
|
|
|
When LoadRomFiles() fails, or the reios setting is on, the core starts
|
|
its HLE BIOS instead and loads only the flash, if present
|
|
(ref: core/nullDC.cpp:183-200, core/hw/holly/sb_mem.cpp:58-64).
|
|
|
|
Upstream resolves the directory as <data dir>/data/, the data dir
|
|
being ~/.reicast when it exists, else $XDG_DATA_HOME/reicast or
|
|
~/.local/share/reicast, then each $XDG_DATA_DIRS entry plus /reicast
|
|
(ref: core/nullDC.cpp:182-188, core/stdclass.cpp:83-100,
|
|
core/linux-dist/main.cpp:287-326, 355-379). The paths below are
|
|
relative to that data dir. Recalbox patches nullDC.cpp to read and
|
|
write both files in /recalbox/share/bios/dc/ instead.
