Programming / Re: Best Assembler/Disassembler
« on: October 15, 2017, 01:38:03 am »
I do not know what is best but what works generally very well if you wanted to reverse engineer code is a combination of static and dynamic analysis techniques (disassembly and debugging). For disassembly, I used IDA Pro and several additions (loaders, plugins) that enabled it to load NES ROM dumps and to export symbols into a format that could be loaded into the FCEUXD SP debugger. This allows for comfortable side-by-side analysis of the code with names etc. exported from IDA visible in the debugger.

The tools for IDA are available here http://www.romhacking.net/utilities/627/
FCEUXD SP can be grabbed here http://www.the-interweb.com/serendipity/index.php?/categories/9-FCEUXD-SP

Since I haven't used an assembler to reassemble the reverse engineered ROM so far, I have no recommendation on that.

sorry for reviving this topic. if you're still interested, I wrote some examples a few years ago. but they work on emulators, only. Hope you find the information useful anyway.
