Hello Community,

Does anybody think making a tool like this makes any sense?
Let's say it should help working with some ROMs and .COM-files, ideally supporting memory mappers.

as for .COM, there exists DBG by Leonid Baraz, I use it for 30 years.

And if you don't stick to running the debugger on MSX itself, openMSX has great scriptable debugger with a lot of features.

Super-X with NYYRIKKI improvements
Also very good tool.

Also worth taking a look at Compass, which has a disassembler + debugger, with mapper support.

OP is talking about interactive disassemblers. The only Z80 ones I know of are Ghidra ( https://ghidra-sre.org/ ) and IDA Pro ( https://www.hex-rays.com/ )
I think neither of them support mappers, but Ghidra is open source so it could be added. Writing such an application from scratch seems like a lot of work!

spacemoai is correct Smile

The point was making a PC based GUI app that would help create .ASM-level sources and/or maps for some binary code of interest. I've made something like that many years ago as a part of MSX Recompiler (for DOS).
Now was thinking about trying this once more and without the 'recompilation' goals.
I tried IDA recently with Z80 target, but overall the way it works is too cumbersome.
Never tried that Ghidra though.

Sounds interesting, in that case, it’d be nice if it also works on macOS Wink.

Does it count as interactive ?

Hmm... I don't know if Z80DIS (for CP/M) can be considered as "interactive disassembler", but at least the user interface is straight from the 70's. Smile

Indeed this idea sounds very interesting... I just downloaded Ghidra as well as I've somehow completely missed to hear about it... So far I've not made heads or tales out of it's logic, but it definitely looks interesting... though I already have a feeling that it is way too complex giant for any MSX need I can imagine. I think there is definitely a place for a less complicated, more straight forward interactive tool.
