Ghidra with illegal opcodes
Recently, Kakka / Extend added 6510 illegal opcode decoding support for the Ghira fork, which I have been using on my C64 game mods.
Note that you must choose the 6510 variant of MOS6502 to use it as a CPU for your binary.

And binaries for Linux and Windows here also, the c64 byte viewer as a plugin can be found:

I don't know how to use the debugger with ghidra, so I don't know if those illegals work ok, but at least they seem to work ok on the code lister.
Ghidra is a pretty good replacement for the IDA Pro; at least, you cannot beat the price.
I update those builds semi-randomly with the latest updates from the official ghidra tree. |
