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.

Android package com.fastemulator.gbc, closed source, sold on Google Play, reached by
|
|
ES-DE through its MY-OLDBOY find rule and started with android.intent.action.VIEW on
|
|
the content URI of the game. Two builds carrying the developer certificate sha256

|
942e532dc3a3608a1d04760b8e1b09a2f11c0c8f64ae8bb441f0c8ab1122a7ab are read here: 2.0.0
|
|
(versionCode 90022, minSdk 21, targetSdk 33, arm64-v8a and armeabi-v7a, bundletool v1
|
|
signer and the Play source stamp) and 1.5.1 (versionCode 90020, minSdk 9, armeabi,
|
|
v1 signature verified entry by entry). Line numbers below are those of 2.0.0 and
|
|
native addresses are arm64-v8a of the same build; 1.5.1 addresses are its armeabi
|
|
library. 2.0.2 (versionCode 90024) is the current Play build, offered by no mirror
|
|
reached here.
|
|
|
|
Emulation runs in libgbc.so behind a JNI bridge (Link.java:23,29-97). Content is a
|
|
.gb, .gbc, .cgb or .dmg document, or the first entry with one of those extensions in a
|
|
zip document (g.java:74-81,124-133). A registered .ips or .ups patch is applied to the
|
|
loaded image when autoIPS is on (EmulatorActivity.java:2049-2057, Link.patch).
|
|
|
|
The machine is chosen by consoleType2, one of auto, gbc, gb, gba or sgb
|
|
(res/xml/settings_advanced.xml, console_type_entryvalues, EmulatorActivity.java:1168).
|
|
The native setter maps those names to 0, 2, 1, 0x12 and 0x21 and then resolves them
|
|
against the cartridge header: bit 0x80 of byte 0x143 keeps Game Boy Color, otherwise
|
|
byte 0x146 equal to 3 gives Super Game Boy under auto, and everything else falls to
|
|
Game Boy (libgbc.so 0x29e74-0x29f30, 0x2436c-0x243bc). Super Game Boy allocates its
|
|
own 0x2200 byte state (0x24420-0x24438).
|
|
|
|
Two boot ROMs are the files the user supplies, one per machine, and the resolved
|
|
machine decides which one is installed: type 1 takes the 256 byte image, type 2 takes
|
|
the 2304 byte image, both into the same area, and any other type clears the flag that
|
|
records an image (libgbc.so 0x2446c-0x2454c). Game Boy Advance and Super Game Boy
|
|
modes therefore run without one. The library carries no image of its own, and on reset
|
|
the area is passed only when the flag and the reset argument are both set, null
|
|
otherwise (0x24550-0x245a8), which is the state the application ships in.
|
|
|
|
Both files are read only while Boot BIOS is on, off until the user turns it on, and
|
|
both pickers declare it as their dependency (res/xml/settings_advanced.xml). A save
|
|
state made under the other setting returns -5 and reports "The save file requires
|
|
using the BIOS file." (EmulatorActivity.java:898), and a link connection whose peer
|
|
disagrees returns 3 and reports "BIOS settings do not match!"
|
|
(EmulatorActivity.java:743).
|
|
|
|
Shaders are read from the assets of the separate package com.fastemulator.shaderpack,
|
|
whose own shaders and shader_names arrays name them, with a store link offered when it
|
|
is absent (EmulatorActivity.java:1513, settings/EmulatorSettings.java:405,419-423).
|
|
Battery saves, real time clock files, states, cheats, screen layouts and key maps are
|
|
written by the application under its external files directory (y0/d.java:13-43,
|
|
Console.java:58). The only file calls left in the library are those saves, the gzipped
|
|
states and one stat on /data/data/com.fastemulator.gbc.
