Using SofaRun to start the demo from a GR8NET on a Sony MSX2+, it just reboots the machine after loading the ROM. What settings do I need?
Try it now. It woks on OpenMSX now, but I don't have real hardware.
It still crashes my Japanese Sony HBF1XV MSX2+, but it does work on my Dutch Philips VG8235 MSX2.
