ReSrc4 - MC680x0 Disassembler
Portable Amiga 68k Hunk File Disassembler.
This disassembler was tested against the Amiga game Civilization (ECS) and Lightwave for FPU support.
Features
Library Call Recognition
It attempts to convert library calls into a more readable format. For example:
jsr (-552,a6) will be converted to jsr (_LVOOpenLibrary,a6) when it can identify that a6 holds the ExecBase.- It can also detect calls to DiskFont, Dos, Graphics, and Intuition library calls.
Jump Table Recognition
There is also some JumpTable detection but its far from perfect.
You will likely need to create a config file and use the Relative16 option.

Hunk file support
Again, only what is needed has been implemented, so it's a little limited. The original Civ game did not include Symbol, DRel32, and Relloc32Short, but when I assembled the disassembled source with vasm, those hunks were used.
Hunks Supported:
- HUNK_CODE (3E9)
- HUNK_DATA (3EA)
- HUNK_BSS (3EB)
- HUNK_RELOC32 (3EC)
- HUNK_SYMBOL (3F0)
- HUNK_DEBUG (3F1) [Skipping]
- HUNK_END (3F2)
- HUNK_HEADER (3F3)
- HUNK_DREL32 (3F7)
- HUNK_RELOC32SHORT (3FC)
