POM2

POM2 emulates Apple II. It reads 16 files, none of them required: it starts games without them.

The app reads its files from this folder:

%LOCALAPPDATA%/POM2/

Searched before the files shipped beside the executable.

Technical notes

Apple ][, ][+, //e, //c and //c+ emulator by Arnaud Verhille, C++ with an ImGui frontend, plus a browser build and a headless CLI. Nine machine profiles (src/SystemProfile.cpp:32-305): Apple ][ Original, ][+, //e Unenhanced, //e Enhanced, //c, //c Plus, and PAL variants of the //e Unenhanced, //e Enhanced (the default) and //c (Le Chat Mauve).

Every file is looked up by a relative name through findResource (src/ResourcePaths.cpp:178-251): the per-user data directory (~/.local/share/POM2, ~/Library/Application Support/POM2, %LOCALAPPDATA%\POM2) when it really is per-user, the executable directory, its parent, ../share/POM2, the temp fallback data directory otherwise, then the working directory and its two parents. The first hit wins. Release packages ship the whole roms/ tree, the fonts, the About photo, the two keyboard photos and the pic/retro artwork (packaging/bundle.manifest:39, 50-61).

Machine firmware is a probe chain per profile, first name found wins (SystemProfile.cpp romProbeOrder, src/ProfileSwitch.cpp:136-154): ][ Original apple2o.rom, apple2.rom ][+ apple2p.rom, apple2.rom //e Unenhanced apple2e_unenh.rom, 342-0135-b.64.rom, apple2e.rom //e Enhanced apple2e.rom //c apple2c-32Kv0.rom, apple2c-16K.rom, 3420033a.256 //c Plus apple2cp.rom, apple2c-plus.rom, apple2c-32Kv0.rom With no candidate the machine runs on a $D000-$FFFF stub and the Welcome panel opens (src/MainWindow.cpp:334-342). A first run with no //e image falls back to the ][+ chain (src/MainWindow.cpp:239-252). Memory::loadAppleIIRom (src/Memory.cpp:175-262) maps 12 KB at $D000, 16 KB at $C000, skips the 4 KB pad of a 20 KB ][+ dump, and slices a 32 KB dump by profile: //e images carry the firmware in the upper half, //c and //c+ images are two firmware banks with bank 0 in the lower half (src/SystemProfile.cpp:432).

Character generators follow charRomProbeOrder per profile, or the locale picked in the toolbar (src/CharRomCatalog.cpp:42-91, src/ProfileSwitch.cpp:156-162). Memory::loadCharRom accepts 2 KB, 4 KB and 8 KB dumps (src/Memory.cpp:343-376). An 8 KB dump is two 4 KB banks, loaded as one bank or kept dual-bank with annunciator 2 selecting the live set.

Peripheral ROMs are read when the card is plugged (src/SlotCardFactory.cpp). The Disk II carries the 341-0027-A boot PROM and the 16-sector P6 sequencer built in (src/DiskIICard.cpp:136-149). CFFA, Liron, Workstation, the MC68705 mouse card, the 1981 Grappler, the Apple Parallel Interface, the Videx Videoterm and the Apple Memory Expansion Card leave the slot empty without their dump. Grappler+, ThunderClock+ and the Super Serial Card run a synthetic ROM instead, and TransWarp accelerates without its boot firmware. The catalogue behind the ROM Status panel (src/RomCatalog.h) lists every name in probe order with the size the loader enforces, what a missing dump costs (degraded, card unavailable, unused) and, where POM2 vouches for a dump, its CRC32. The panel hashes each present file (src/RomStatus_ImGui.cpp:176-203, 404) and lists the Virtual ][ recordings with a decode check (src/RomStatus_ImGui.cpp:314-380).

Help > Download missing ROMs (src/RomFetch.cpp:68-301) fetches 45 files, 43 distinct dumps, with curl from raw.githubusercontent.com/Abdess/retrobios, pinned to HTTPS (src/RomFetch.cpp:734-750). Every entry carries a SHA-256, fourteen a CRC32 as well, and a download is installed only when its size, CRC32 and SHA-256 match (src/RomFetch.cpp:631-667). A present file is re-checked with the same gate and, when it is not the catalogued dump, replaced after a copy to roms-replaced/ under the data directory (src/RomFetch.cpp:581-629, 840-860, 869-887). A 12 KB apple2p.rom is the one alternate size kept as is. Nine entries are members of MAME romsets, read in-process (src/ZipMember.cpp): apple2e_unenh.rom is 342-0135-b.64 then 342-0134-a.64 from apple2e.zip, mouse_341-0270-c.bin is 341-0270-c.4b from a2mouse.zip, ssc_341-0065-a.bin is 341-0065-a.bin from a2ssc.zip, grappler_eps-1.bin is eps-1_c1981.u6 from a2grappler.zip, 341-0057.bin is 341-0057.7b from a2pic.zip, and the four Videoterm files come from a2vidtrm.zip. Downloads land in the per-user data directory's roms/ (src/RomFetch.cpp:808-828). Unavailable in the browser build (src/RomFetch.cpp:932-937).

The floppy mechanical sounds are MAME's samples/floppy set, read from roms/floppy_samples/ as two banks of ten WAV files prefixed 525_ and 35_ (src/FloppySoundDevice.cpp:83-121, src/MainWindow.cpp:351-364). A missing sample is logged and the drive stays silent. A second bank, the Virtual ][ recordings, is read from the folder picked with Import sounds in the audio mixer, stored as mechanical_sound_path (src/MainWindow_AudioPanels.cpp:349-381), then from roms/virtual_ii_sons/, and on macOS from Virtual ][.app/Contents/Resources/ under /Applications and ~/Applications (src/MainWindow.cpp:365-381, src/VirtualIISoundCatalog.h:34-45): eight drive and switch takes under lecteur/ and interface/ (src/VirtualIISoundCatalog.h:19-28) and one printer loop under imprimante/ (src/VirtualIISoundCatalog.h:30-31). The bank is selectable once Disk Rotation, Move arm, Disk Insertion and Disk Removal have loaded (src/FloppySoundDevice.cpp:192-228). Each take is tried under its path, then an .aiff path as .wav, then the bare file name, then the bare name with .aiff turned into .wav or .wav into .raw, so a Virtual ][ Contents/Resources/ folder is read as it is (src/VirtualIISoundCatalog.h:47-66, src/FloppySoundDevice.cpp:176-190). The packaging manifest keeps the directory out of release packages (packaging/bundle.manifest:92-95).

The nine takes come from Contents/Resources/ of Virtual ][.app in VirtualII.dmg, the free download on virtualii.com (Virtual ][ 13.3). The five .aiff files are copied unchanged. The four .wav files are the headerless Boot.raw, Disk Rotation.raw, I-O Error.raw and Matrix Printer.raw behind a 44-byte RIFF header, the data chunk being the .raw file byte for byte. The header states PCM, one channel, 44100 Hz, signed 16-bit little-endian. That is the stream Virtual ][ builds for these files: every playWithSoundFile:sampleRate:sampleSize: call passes 44100.0 and 16, and SoundRepeater fills an lpcm AudioStreamBasicDescription with one channel, the signed-integer flag for 16 bits and no big-endian flag. POM2 decodes the takes through miniaudio into mono float at the file's own rate. An .aiff whose FORM chunk declares more bytes than the file holds is rejected. A file miniaudio refuses is read as mono signed 16-bit little-endian 44100 Hz when it ends in .raw, and through AudioToolbox on macOS when it ends in .aiff (src/FloppySoundDevice.cpp:135-168, src/PrinterSoundDevice.cpp:80-103, src/VirtualIISoundLoader.h:17-104).

The screen sits in a Monitor II bezel, pic/retro/monitor/monitor2.png, on by default (src/MainWindow_Screen.cpp:371-372), and the Drives window shows a picture per drive state from pic/retro/drives/ (src/RetroArtwork.cpp:44-91, src/MainWindow_DriveRack.cpp:109-120). Without a picture the screen has no bezel and the drive is drawn as a vector mechanism (src/DriveRack_ImGui.cpp:57-61). The FujiNet card runs FujiNet-PC Apple v1.5.2, a separate program the release packages carry under fujinet-pc-APPLE/<platform>/ (src/FujiNetRuntime.cpp:38-62, packaging/fujinet/stage.py:20-31).

Media named by the code are not firmware and are not listed here: the browser demo boots bundled_disks/DIX-fix.po on the //c PAL preset (wasm/shell.html:114-117, src/main.cpp:313-319), and the headless CLI mounts disks_5.4/dos33_master.dsk by default (src/pom2_headless.cpp:265-267). Disk, tape and hard-disk images are browsed from disks_5.4/, disks_3.5/, hdv/, floppyemu/, bundled_disks/, cassettes/ and prodos_folder/ next to the executable.

  • Shipped in roms/ since v0.9.3. The dump is the card's boot firmware, 65C02 code overlaid on $F000-$FFFF until it writes $C072: it tests RAM and the Apple ROM, then boots through the Apple reset vector. Without it the card accelerates and the machine boots straight into the Apple ROM. The shadow steps aside for a main ROM reload and covers the new firmware.
