CydandClaude Opus 4.8 981d98d784 VDB: dump captured palettes (VDB_PALDUMP) + swatch renderer

VDB_PALDUMP=<prefix> writes each completed 768-byte palette load to
<prefix>N.rgb (256 RGB entries per VDB display group). render_vdb_palettes.py
renders each as a 16x16 swatch grid + linear ramp.

First capture: pal1 (aux1) is a structured red/green/olive/black color map
(2-bit R x 2-bit G) -- likely the color display's status coloring; pal0
(secondary, dynamic ~29 reloads) and pal2 (aux2) are grayscale, sampled black
mid-animation. Palettes are the per-display color maps the VDB applies when
splitting the framebuffer to the six monitors.

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.
