Hi Peter, Thanks for the bug report - it was caused by the FCode ROM containing some Forth that depended upon some specific OpenBIOS variables that weren't present in OBP.
If you replace the QEMU,tcx.bin from QEMU 1.7 with the one attached to this bug report then you should be able to boot your VM once again - please let me know if this resolves the problem for you.
