IDA Disassembler

[kamelito]

is it possible to disassemble 68k using the free version of IDA?

@SparkyNZ I will look and see if I still have these files archived somewhere.

The most annoying thing about IDA and its 68k-module is that it does not disassemble pc-relative code correctly, for example:

"lea label(pc),a0"

will be translated to

"lea label,a0"

and this is NOT CORRECT since the opcodes are "totally" different.

IS there anything that can dissassemble Atari ST .prg files correctly with proper relocated labels etc?

[mark_k]

Does ST2Amiga on Fish disk 448 do what you want (in conjunction with ReSource)?

I'd say Easy Rider or TT Digger both are native ST disassemblers.

@SparkyNZ I've attached the plugin and source in the zone. Hope you find it useful.

Hello there. Sorry about the thread necromancy, but the original link to @crabfists' IDA plugin is dead. Would anyone provide an alternative source? Thanks!

[crabfists]

I’ll see if I still have it...

[crabfists]

Sorry for the delay. I finally found it.

I made a quick Sourceforge page so it won't disappear again.

Can't IDA do this job..?

[jarre]

For all who interested i have IDA pro v6.8

I'm a fan of radare2, it's open source and text (terminal) based, currently supports these platforms (68k highlighted).

I have used the 68k module for reversing, but not for Amiga, been using native tools for that (hrtmon, resource, etc.).

Any disassembler which supports 680x0 CPUs can do this job. I prefer ReSource for this. The (rather obvious) trick here is to convert the Atari ST files to something which Amiga disassemblers can easily handle.

I did try Radare2 "back in the day(tm)" (shortly after it's initial release), it was so buggy/awful I had to stop using it before I smashed something...
There is a hilarious presentation on Youtube by the author "dispelling myths" about Radare2 being buggy and hard to use - which includes him not being able to compile the latest version, and it segfaulting every 2 minutes while he tries to reverse a simple example program!


That said, I have used it more recently for x86 stuff, and it's actually a very useful tool these days - but personally for the more 'unsupported' architectures (Amiga included) I wouldn't choose to use it.


Stick with IDA (ok, pc-relative stuff is an annoyance but you can tell by the instruction size if an LEA is relative or not, it's rarely a critical issue), or tools on Amiga (AR, Resource, etc.)

I found a bug radare2, reported it via IRC, got a working fix five minutes later and was asked to write a regression test for it which was pulled.

If you feel at home with unix style environments and shells like bash, then I can't recommend radare2 enough, it's getting better every day.
