An internet search for "68000 disassembler" brought numerous results. Online disassembler, github projects, comparison of different disassembler ...
I assume you did the internet search before you posted your question. And I assume you were not satisfied with the results.
So, what exactly are you looking for?
I am involved in a reverse-engineering project that includes an MC68020 processor. I am an electronic engineer and
I don't have enough experience for reverse-engineering of the processor programs.
Please help me convert binary code to assembly.
Thanks a lot.
What help do you need?
The online version should give a brief description.(and any other, too)
Usually just upload a binary and get back the assembly file.
