Where exactly did 123 come from? (The screen is 128x64). Now, on to the
conversion. Although converting from Z80 assembly to 68000 aseembly is
probably possible (although not fun), converting all the 85 ROM calls to 92
ROM calls is not possible (without writing custom 68k calls that would be
stored in the program, making it more bloated than it already would be).
