Another slightly esoteric microcontroller in a product I'm looking at - the NEC 78K0R microcontroller. This is a 16-bit extension of the 78K0. The 78K0 can be disassembled in IDA Pro, but not the 78K0R.
Renesas Cubesuite allows viewing of disassembly of code compiled/assembled through it, as does IAR Workbench, but I can't see a way of loading a bin or hex file into these for disassembly.
KPIT GNU binutils has support for the RL78, which has a lot in common with the 78K0 instruction set, but is still very different.
Is there a free disassembler for these microcontrollers?
