CydandClaude Fable 5 7670d40b37 VDB heads: 4-head cockpit layout (VPX_COCKPIT=1), drop exploratory windows

- VPX_COCKPIT=1 places the four VGA heads as borderless windows:
  Division main 800x600 @ 0,0; radar (win0) 640x480 @ 800,0; MFD heads
  win3/win4 640x480 @ 1440,0 / 2080,0 (heads 3+4 are driver-spanned
  into one 1280x480 canvas). VPX_MAIN / VPX_WIN<g> = x,y[,w,h]
  overrides any window without a rebuild; default debug layout kept.
- Remove exploratory win1/win2 (bits 0-7 via static palettes); keep the
  0/3/4 numbering so win<g>.bmp dump names stay stable.
- Sync commit copy with the build tree: per-head palette decode in
  pal_draw() and device-side BMP capture (VPX_DUMPDIR).
- RIO-NOTES: document the PCSPAK DISABLE_AND_DIE patch (error-3 crash
  on RIO resets); restore the terrain-shadow section heading it ate.
- Add gauge_rio{,_log}.conf launch configs.

VPX device — DOSBox-X integration

Our original source for the emulated Division VPX link adapter. Kept here under version control because the DOSBox-X source tree itself (emulator/src/, ~490 MB) is git-ignored.

vpxlog.cpp — Phase 1 logging device. Impersonates the INMOS C012 link adapter at I/O base 0x150, answers status reads so the game keeps transmitting, and logs every access to $VPXLOG. (Phase 2 will grow this into a responding transputer-monitor + i860-loader + frame-stream renderer, or fork into a separate vpx.cpp.)

Applying to a DOSBox-X source checkout

Tested against DOSBox-X v2026.06.02, MSYS2 mingw64.

Copy the device in:

cp emulator/vpx-device/vpxlog.cpp  emulator/src/src/hardware/vpxlog.cpp

Add it to the hardware build — in src/src/hardware/Makefile.am, append vpxlog.cpp to libhardware_a_SOURCES (we inserted it after glide.cpp).
Call the init — in src/src/gui/sdlmain.cpp, declare void VPXLOG_Init(); next to the other *_Init() prototypes and call VPXLOG_Init(); right after GLIDE_Init(); in the machine bring-up sequence.

Build:

cd emulator/src
./build-mingw-sdl2 --enable-debug=heavy

Output: src/src/dosbox-x.exe.

Running

set VPXLOG=C:\VWE\TeslaRel410\emulator\vpxlog.txt
emulator\src\src\dosbox-x.exe -conf emulator\capture.conf
python emulator\analyze_capture.py

With VPXLOG unset the device is inert and the build behaves like stock DOSBox-X.
