Seriously, try IdaPro. You may find it more to your liking.
I used IDAPro before Ghidra came out.

Like I said, I havent had much use for it yet, but I did get a chance to read the manual and it seems to fit the bill quite nicely for what I wanted from a disassembler.

If anyone would like a crack at disassembling the code I can post a link to a ROM image and what I guess to be the base address. ;-)
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

If you post it, I'll give it a try in Ghidra.

OK, here it is (start address 0xfefe0000): http://www.lingula.org.uk/~steve/share/ ... V2.9.2.bin

It's a direct dump of the EPROM.

I may be getting somewhere with Ghidra, as long as I ignore a lot of the first code which deals with the address translation tables. which the C decompiler barfs on.

Im not one for wearing tin foil hats, but I draw a line with my lack of paranoia when it comes to downloading NSA warez.

It was a while ago now, so I may be mistaken, but I believe the demo version doesnt include the full available CPU ranges, but it does have 68k as one of the freebies.

Ghidra is open source so it being NSA is irrelevant. It’s a gorgeous tool. If I worked on Tor I’d be suspicious but retro computing... nah.
