Photon driver for VirtualBox 6.0

Does anyone know which Photon graphics driver to use in a VirtualBox 6.0 virtual machine for QNX 4,25 with QNX Windows (i.e. NOT Photon if that makes any difference) ?

Since our application uses QNX Windows we have to start any Photon driver through gr.phi which means that the usual method of leaving these things to crttrap has not really been possible…
At last attempt, trapper generated start commands for some useful resolutions (1024x768 and 1280x768 for example), but only in 32-bit mode. The result was corrupted graphics in QNX Windows - I think it might be limited to 8-bit mode (256 colors).


Just a guess here. Is there a VESA driver?
