You could have a fds(machine_config &config) method which adds what's in if (bFDS) and have void rm380z34d(machine_config &config) { rm380z34e(config); fds(config); } On Tue, May 21, 2024 at 4:18 PM...
Known. Do you know whether the mu100 can actually work with the plg150-ap? Right now it sends a bunch of data on startup to the plugin board which blows up...
Yeah, why the vl board doesn't work is a lot less clear...
I think the intertwining of hd and floppy makes the code rather hard to follow though. Also, since hdd and floppy support are effectively two different devices (I mean, needing...

My sources are https://github.com/ijor/fx68k , https://og.kervella.org/m68k/schem and a bunch of other work. You can refer to https://raw.githubusercontent.com/mamedev/mame/master/src/devices/cpu/m68000/m68000-sdf.cpp to see the decompiled-from-microcode behaviour of each instruction.
Nice one, I would have no problem going for it.
Fun, they started from the same idea but missed the fact that you can drop the comparator and the second adder by leveraging the carry.
It should be an independant feature though.
