Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms. validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.

Member of the EX Emulator series by Robert Broglia, which targets Android and
|
|
Linux (README.md:1,3-4,12-13) and keeps iOS and Pandora build shortcuts in the
|
|
tree (NGP.emu/ios.mk, NGP.emu/pandora.mk). Published as com.explusalpha.NgpEmu
|
|
(NGP.emu/metadata/conf.mk:2,4,6,7) and reached by ES-DE through its NGP-EMU
|
|
find rule, which only the Android rule set carries. Mednafen's Neo Geo Pocket
|
|
module, itself descended from NeoPop, is vendored under NGP.emu/src/ngp
|
|
(NGP.emu/metadata/conf.mk:8, NGP.emu/src/main/AppMeta.cc:27) on the 1.32 line
|
|
(EmuFramework/include/shared/mednafen/mednafen-config.h:167) and driven by the
|
|
app's own video, audio, input and save layers. Three files differ from the
|
|
Mednafen 1.32.1 release, all of it frontend plumbing: the pixel format and
|
|
sound rate hooks, the input latch and the flash file I/O move to the app
|
|
(NGP.emu/src/main/Main.cc:84,102,118-131, NGP.emu/src/main/system.ccm:87,93).
|
|
The TLCS-900h disassembler is left out of the build
|
|
(NGP.emu/src/CMakeLists.txt:6-32). Content is read from .ngp, .ngc, .npc and
|
|
.ngpc files (NGP.emu/metadata/conf.mk:5, NGP.emu/src/main/AppMeta.cc:31-34,
|
|
NGP.emu/src/ngp/neopop.cpp:336-337). An archive is opened by the framework,
|
|
which keeps the first entry passing that same filter
|
|
(EmuFramework/src/EmuSystem.cc:392-412).
|
|
|
|
The content image is the only one the app loads. It is read into a 4 MiB
|
|
buffer, hashed for the save file names and handed to the module, which refuses
|
|
an image over 8 MiB (NGP.emu/src/main/Main.cc:80-85,
|
|
EmuFramework/src/shared/mednafen-emuex/MDFNUtils.hh:133-146,
|
|
NGP.emu/src/ngp/neopop.cpp:183-193). The BIOS is built in memory rather than
|
|
read: bios_install fills a 64 KiB array with the 27 system call vectors, writes
|
|
opcode 0x1F at each target, copies an 0x800 byte system font held in the binary
|
|
to 0x8DCF and closes the image with a RETI and an infinite loop
|
|
(NGP.emu/src/ngp/bios.cpp:29,50-180,182-239, NGP.emu/src/ngp/neopop.cpp:211).
|
|
That opcode is bound to the HLE handler in the interpreter decode table, and
|
|
the handler answers only from the 0xFF0000 region
|
|
(NGP.emu/src/ngp/TLCS-900h/TLCS900h_interpret.cpp:921-926,
|
|
NGP.emu/src/ngp/biosHLE.cpp:43-47). The same array is what the memory map
|
|
returns for the BIOS region and where the font routine reads its glyphs
|
|
(NGP.emu/src/ngp/mem.cpp:121, NGP.emu/src/ngp/biosHLE.cpp:221). The NGP
|
|
Language menu item feeds the ngp.language setting, written to RAM at boot
|
|
rather than selecting a file (NGP.emu/src/main/EmuMenuViews.cc:31-40,
|
|
NGP.emu/src/main/options.cc:82-83, NGP.emu/src/ngp/mem.cpp:620,
|
|
NGP.emu/src/ngp/neopop.cpp:286-299).
|
|
|
|
No firmware path exists by construction: the app answers Mednafen's file name
|
|
request for save states, saves and save backups only, and any other kind ends
|
|
in unreachable() (NGP.emu/src/main/options.cc:96-106). Cheat loading and IPS
|
|
patching are compiled in from the shared Mednafen sources and called from
|
|
nowhere (EmuFramework/src/shared/mednafen/mempatcher.cpp:251-254,
|
|
EmuFramework/src/shared/mednafen/file.cpp:38-53). Per content the app writes
|
|
and reads back a .ngf image holding the cartridge flash, plus save states and
|
|
NgpEmu.config (NGP.emu/src/main/Main.cc:53-73,118-131,
|
|
NGP.emu/src/main/system.ccm:76, NGP.emu/src/main/AppMeta.cc:28). ui.png,
|
|
gpOverlay.png and the shader sources are drawn from the application bundle
|
|
(EmuFramework/include/emuframework/AssetManager.hh:61-66,
|
|
EmuFramework/src/AssetManager.cc:58-65,
|
|
EmuFramework/src/VideoImageEffect.cc:163-173). The app declares no bundled
|
|
content, the framework definition defaulting to an empty span
|
|
(EmuFramework/src/AppMeta.cc:40,
|
|
EmuFramework/include/emuframework/AppMeta.hh:66-68).
