I've just looked at the ASM, LST and HEX of Tim's version of Minefield that I have working here. Phil was right to spot that the execution address contained within the second last line of that Intel Hex file at FFFE/FFFF is incorrect (0F00) and it should instead be 0FBD, so (777xxxx) try loading Phil's binary of Minefield at address 0F1F but execute it from 0FBD instead.

At OFBD there is, as I predicted, some code to set up the 8154 ports to put the VDU into a specific configuration but that doesn't matter as the VDU settings are not influenced by the 8154 port pins in the MAME emulator.

This particular game needs the VDU pointed at 0F00 and 0B00 and in Character mode.
