Replace the in-render-window palette strips with three separate 640x480 windows, one per VDB display palette (secondary/aux1/aux2). Each has its own GL context (rt_main wglMakeCurrent-s each per tick) and shows the palette as a 16x16 color grid, redrawn every 50ms so it animates live regardless of the VPX render cadence. make_gl_window() factored out; strips + VPX_VDBSTRIP removed. Confirmed live: aux1 = red/green/olive/black status checkerboard, aux2 = a 4-region color map (green/blue/red/purple, 64 entries each), secondary = the animated one (black between flashes).

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 base0x150, 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 separatevpx.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, appendvpxlog.cpptolibhardware_a_SOURCES(we inserted it afterglide.cpp). - Call the init — in
src/src/gui/sdlmain.cpp, declarevoid VPXLOG_Init();next to the other*_Init()prototypes and callVPXLOG_Init();right afterGLIDE_Init();in the machine bring-up sequence. - Build:
Output:
cd emulator/src ./build-mingw-sdl2 --enable-debug=heavysrc/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.
