The '''**Roland xx''' looks like a boot banner and is called differently in the firmware. I'm sure that's why it has different start and stop markers. Ditto for the early Version string. Interestingly, the early Version is way at the other end of the addresses in the code. This adds to the DFU / Bank swap theory.
When I finally load the firmware (I still haven't at this point) I spend ages looking for what calls these strings. I find it difficult to navigate but fascinating. It is difficult to navigate any production firmware disassembly I expect. I have no prior experience, but it seems the H8300H is kind of a different level, a bit of an oddity. It's used a lot in Japanese electronics. It is in a lot of Roland devices. Apparently it interleaves code and data frequently which makes static disassembly trickier. '''''Especially in Cutter, which won't decompile H8 instructions (it either links to Ghidra method, which does not support the H8, or JS, which can't de-compile either)'''.''
