Linkboy 3.11.4 adds a cartridge logo check before the BIOS boot and a second built-in BIOS variant. My Boy! 2.1.1, My OldBoy! 2.0.3, FPse 13.0 and FPseNG 1.17 circulate only rebuilt: their profiles stay on the last genuine build and name the release.

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. 2.0.3 is the current Play build, offered genuine by no mirror reached here.
|
|
One rebuilt copy was rejected on its certificate: 2.0.1 (C=IN), served under a 2.0.3
|
|
page.
|
|
|
|
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.
