Phantasy Star II Disassembly

Source Code

Description:

This is a disassembly for the US/EU version of Phantasy Star II. It targets the Macro Assembler AS.

The asm code produces a byte-perfect copy of the original US/UE ROM.

The code can be changed freely without worrying about shifting data since every pointer has been labelled so that the assembler can calculate addresses and offsets by itself. Comments were included as well to explain what certain parts of code do.

Both the m68k and z80 assembly instructions can be used for the same assembler.
