Vendored 86Box EMU8000 core (GPL-2, emu8k.cpp/.h + shim) plus vweawe.cpp: two cards at the production addresses (0x620/0x640 register triplets), rear-card DSP/mixer stub at 0x240, synthesis on an autonomous render thread with direct winmm output so sustained voices ride through emulation-thread stalls (RIO staging retries) like the real silicon did. WC sample-counter interpolation between render chunks keeps HMI SOS busy-waits fast. VWE_AWE32/VWE_AWE_ROM/VWE_AWE_RAM_KB/VWE_AWE_SHIFT/ VWE_AWE_LEAD_MS/VWE_AWE_DUMP/VWE_AWE_LOG env knobs. emulator/roms: the AWE32 1MGM GM ROM dumped from our own pod card (SF2) plus the reconstructed raw image the emulated EMU8000 loads. The HMI driver refuses the AUDIO*.RES SoundFont upload without it (banks declare irom=1MGM) -- that was the root cause of the first silent runs; full debug chain in SOUND-NOTES.md. Repo serves the pod-owner community only. .gitignore: drop the ROM excludes and un-ignore ALPHA_1/ and sda4/ (committed separately). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Card ROMs
|
||
|
||
- **`1mgm.sf2`** — the AWE32's 1MB "1MGM" General MIDI sample ROM, dumped
|
||
from one of our own pod AWE32 cards (the cockpits each carried two, with
|
||
2x 30-pin DRAM SIMMs). Preserved here because the pod audio banks
|
||
(`ALPHA_1/REL410/BT/AUDIO/AUDIO*.RES`) declare `irom=1MGM`, and the HMI
|
||
SOS AWE32 driver refuses the SoundFont upload if the card has no GM ROM.
|
||
- **`awe32.raw`** — the same content reconstructed as the raw 1MB ROM image
|
||
the emulated EMU8000 loads (`VWE_AWE_ROM=emulator\roms\awe32.raw`):
|
||
the SF2's `smpl` chunk (1,047,588 bytes) end-aligned into a zeroed 1MB
|
||
buffer, with the `1MGM` ID words (`0x314D 0x474D`) at word offsets 2–3.
|
||
Rebuild with any RIFF parser if the SF2 changes; the recipe lives in
|
||
SOUND-NOTES.md.
