Take this line from Tunnels and Trolls:

0x6683A: 0xFF3C: 1111[111]100[111][100] cpSAVE 7, Imm

Imm is actually an invalid effective addressing mode for the cpSAVE instruction, so as I understand it should cause an F-Line thingy. I think Resource disassembles these sorts of invalid instructions as "fRestore ?????" or even sometimes "AFLINE something".

Anyone have any insight into the best way to handle these invalid instructions?

Line-F calls are Human68k DOS calls. You can read more about those DOS calls here: http://datacrystal.romhacking.net/wiki/X68kOSCALL
