You must download the developer version of the program and reboot the MSXVR :
After, switch in config video mode VRAM at 386.
For me at that time the game was still not working properly (bugs, glitchs, freezes, etc.) and crashed the MSXVR.
I had to change the resolution to 1024x754p in config video mode (I use an LCD monitor) and the game work finally properly :)
For me the game works properly at 800x600 but, after playing, if i reboot the MSXVR, i have a black screen, and i have to shutdown the machine and powere-on again ( sometimes a couple of times)
