Read the cores in the Recalbox 10.1.1 x86_64 image (sha1 b3d80ff0). The sugarbox2 core, built from the token-gated v1.5, holds the 59 blobs of the public v0.9 RomData.cpp byte for byte and opens the same paths: only its on-screen keyboard placement differs. eightyone and exel-hence hold every compiled embedded array of their public tags.

Libretro core by Recalbox wrapping Tom1975's SugarboxV2
|
|
(CPC 464, 664, 6128, 464+, 6128+ and GX-4000). Recalbox 10.1.1 builds
|
|
tag v1.5 from a token-gated copy of this repository, and the public
|
|
repository carries v0.9 only, which is the revision read here. The core
|
|
Recalbox ships was read against it: sugarbox2_libretro.so from the
|
|
10.1.1 x86_64 image (image sha1 b3d80ff00d46000de73c470c73b0ffa81f23c600,
|
|
core sha256 eda2d57f9b556c66db95d2b4b755e501c6645de6b9dfc46d901f1f93a1f39c5e)
|
|
holds the 59 compressed blobs of RomData.cpp byte for byte, reports
|
|
library_version 0.1, and opens the same paths. Its on-screen keyboard
|
|
is placed by SetOrigin where v0.9 has SetViewport.
|
|
|
|
Every ROM is compiled into the core as a zlib stream: OS and BASIC for
|
|
each model and language, AMSDOS, the Plus cartridge plus_en.cpr, the
|
|
CP/M Plus, FutureOS, SymbOS and utility expansion ROMs, 57 blobs in all
|
|
(ref: libretro/RomData.h:1-15).
|
|
rom_uncompress() inflates them when the machine is built
|
|
(ref: libretro/LibretroCore.cpp:1098-1107) and they are handed to the
|
|
memory map directly, never through a path
|
|
(ref: libretro/LibretroCore.cpp:1173-1174).
|
|
|
|
The keyboard map files the engine reads are written from embedded data
|
|
into the save directory, only when missing: CONF/KeyboardMaps.ini and
|
|
Keyboards/101_keyboard_linux
|
|
(ref: libretro/LibretroCore.cpp:1477-1502, 2169-2173).

|
exclusion_note: "all CPC, Plus and GX-4000 ROMs compiled into the core as zlib blobs, and keyboard maps written by the core into the save directory"
