A disassembler for ez80 op codes

ez80 Disassembler

This is a quickly made (and pretty blursed) ez80 disassembler.
It takes in hexadecimal ascii coded bincode (whitespace authorized), and it spits out the corresponding assembly.
It assumes adl mode is on, which means it only handles 8 bit and 24 bit wide constants.

One of its quirks is that it puts the suffix before the instruction. For example: push.s hl becomes 52 e5 to which the decompiler gives .s push hl.

Build instructions

There no are dependencies beyond a C compiler:

$ gcc main.c -o ez80dump

Usage

Feed it bincode through stdin.

$ cat file | ./ez80dump

Content of file:

e1 d1 c1
c5 d5 e5
21 00 00 00
19 09
c9

Output:

pop  hl
pop  de
pop  bc
push bc
push de
push hl
ld hl, 0x000000
add hl, de
add hl, bc
ret
