Thirty profiles from the ES-DE batch, each source-verified by the session that wrote it and passing the schema and semantic checks. Five declare no files at all and say why in notes referenced to the code: NGP.emu, openbor, Plastic, Swan.emu and XeniOS. Twenty-eight files come with them, every one declared by the profile that needs it and matching the hash it declares, with no duplicate of anything already held: the NetherSX2 Turnip Classic assets, the Speccy machine ROMs, the Virtual Boy homebrew the app bundles, Snes9x EX+'s bundled game, and sixtyforce's Overrides.plist, which carries a size and no hash because the binary never checks one. supermodel gains the four data files it reads from its install tree, hakux marks its controller map unsourceable now that the asset manager is known to read inside the package, and nethersx2 sheds the two core aliases that belong to the Turnip profiles.

Two Android packages, closed source, sold and given away on Google Play under the
|
|
Pizza Boy A name, reached by ES-DE through its PIZZA-BOY-GBA find rule and started
|
|
with the game passed as the rom_uri extra: it.dbtecno.pizzaboygbapro, the paid build
|
|
the rule names first, and it.dbtecno.pizzaboygba, the free one. Two Play distribution
|
|
builds are read here, both carrying the source stamp: Pro 2.8.13 (versionCode 343,
|
|
Play App Signing certificate sha256
|
|
6b5547246e41921f25eba8abb1bc018729c4f0b8db029debbd3380a2b1ec2fe1), which supplies the
|
|
Java and the resources, and Basic 2.3.3 (versionCode 236, developer certificate sha256
|
|
b3ee584096acf4667bb9346daa9cce19237ef7ce95c99e9260ac89be0f7d6130, CN=Davide Berra,
|
|
O=DBTecno), whose arm64-v8a libpizzaboy-jni.so ships DWARF and an unstripped symbol
|
|
table and supplies every native reference below as its own file and line. Java line
|
|
numbers are those of Pro 2.8.13. Two rebuilt copies of Pro 1.35.11 were rejected on
|
|
their certificate, one signed C=debugging with no source stamp and one signed
|
|
O=APKMODY. 69 of the 77 native methods the Pro declares are exported by the Basic
|
|
core, the three BIOS entry points among them: one core, compiled per package.
|
|
|
|
One system is emulated, Game Boy Advance: the core is built from a tree named
|
|
pizzaboyadvance whose compilation units carry gba.c and no Game Boy core, and the
|
|
three Game Boy Color and Super Game Boy methods the Pro still declares are among the
|
|
eight the library does not export.
|
|
|
|
The BIOS is the one file the user supplies, and it is read only while Load BIOS file
|
|
is on, off by default; the picker and the Run BIOS animation switch, on by default,
|
|
both depend on that box (res/xml/pref_general.xml). In the free package the same
|
|
three preferences are declared android:enabled="false".
|
|
|
|
A per rom Low precision BIOS set to On clears the stored path and makes the core keep
|
|
its own replacement, and one cartridge, checksum 0xc7d89508, forces the same at load
|
|
time. When a real image is installed the boot animation starts execution at 0 rather
|
|
than at the cartridge entry, and a multiplayer session exchanges the CRC32 of the file
|
|
so that both peers run the same one.
|
|
|
|
Everything else the app opens it makes itself: boxart.db and cheat.db are created by
|
|
their own CREATE TABLE, the default skins, the shaders and the cheat descriptors are
|
|
raw resources unpacked at first run, and <rom>.keys is an input recording. The
|
|
obfuscated assets are PairIP tamper protection.

note: >-
|
|
Chosen from any location under any name through the document picker, or, when the
|
|
picked document is named .zip, taken from its first entry; the legacy browser
|
|
offers .gba, .bin and .zip and writes the entry it extracts to bios.bin under the
|
|
application directory. The absolute path is stored and handed to the library,
|
|
which copies it into a 256 byte buffer. At load time the 16 KB BIOS area is first
|
|
filled with a 744 byte replacement compiled into the library, then, if the path is
|
|
set, the file is opened and up to 16384 bytes are read over it and a flag records
|
|
that a real image is installed. Nothing about the file is examined: any read
|
|
returning at least one byte is accepted, and no size, name or hash test exists on
|
|
either side of the bridge. A read of zero bytes leaves the replacement in place
|
|
and logs "Cannot read BIOS file".
