PlayStation emulator forked from psxe, rebuilt around SDL2 frontends and a
|
|
Dear ImGui fullscreen shell. Desktop, Android, iOS, UWP, WebAssembly and
|
|
PSVita builds come out of one tree. The Android application is
|
|
com.nanodata.armsx with the activity com.armsx2.Main, and its Compose
|
|
launcher hosts the same core in process.

A BIOS image is required. Boot stops before a session exists when no path
|
|
resolves, and again when the file cannot be read. Skip BIOS does not change
|
|
that: the image runs from reset and the hook only takes over at the shell
|
|
entry point, once the kernel is built.

|
|
|
psxe_cfg_get_bios_path answers in three steps: the override file when it
|
|
exists, then a scan of the search folder, then the override path unchanged.
|
|
The override is [bios].override_file or -b and defaults to bios.bin under the
|
|
preference path SDL_GetPrefPath("nanodata", "armsx"); the search folder is
|
|
[bios].search_path or -B and defaults to the relative path bios.
|
|
ref: frontend/config.c:1540-1559, frontend/config.c:1385-1404,
|
|
frontend/config.c:677-683, frontend/config.c:54-57
|
|
|
|
The scan reads that folder once, keeps .bin and .rom, and returns the entry
|
|
named bios.bin. Its other branch compares [bios].preferred_model against each
|
|
filename through a normaliser that drops every non-alphanumeric character and
|
|
lowercases the rest, applied to the name including its extension, so
|
|
scph1001.bin normalises to scph1001bin and no model value equals it. A name
|
|
carrying no extension, which would, is dropped by the extension filter first.

Nothing identifies the image beyond that. No name table, no size test, no
|
|
hash. The loader takes the file's own length, allocates it, and the bus maps
|
|
the device from 0x1fc00000 over that same length, which is how the 1 MB
|
|
SCPH-5903 image stays addressable in full.

preferred_model carries 22 values, SCPH-1000 through SCPH-102C, printed by
|
|
--help-model and mirrored by the Android model picker.

ref: frontend/config.c:177-200,

android/app/src/main/java/com/armsx2/config/Ps1Settings.kt:416-423
|
|
|
|
On Android the preference path is the application files directory, so
|
|
settings.toml and the default bios.bin sit there. The BIOS picker copies the
|
|
chosen dump to user_bios.bin and writes its absolute path into
|
|
[bios].override_file. EmulatorActivity passes --bios <files>/bios.bin when
|
|
the package carries an assets/bios.bin, and the in-process launcher repeats
|
|
that check with stat; release 0.1.3 ships no such asset.

The remaining paths the core opens are per game, and are written by the
|
|
emulator or picked by the user: memory cards, created blank at first use;
|
|
save states, rewind snapshots and screenshots; a GameShark .cht catalogue
|
|
named by [cheats].cheats_file; and content-addressed PNG packs under the
|
|
replacements folder of [video].texture_dir.

note: >-
|
|
Any image is accepted, whatever its name and length: the file is read
|
|
whole and mapped at its own size. 524288 is the region psx_bios_init
|
|
declares before the load, and 1048576 the SCPH-5903 image the loader
|
|
names as the exception. The folder scan reaches an image only under the
|
|
name bios.bin; [bios].override_file, -b and the Android picker open a
|
|
path directly.
