Interesting in modifying genesis roms

TenLeftFingers

Just wondering if anyone can point me in the direction of compilers/decompilers to help me do this.

Any other info is appreciated too. For example, what language can I expect to be programming in, assembley or C etc.

Thanks

Not a flucking clue tbh

I assume they be compiled in the format the genesis used to run them so decompiling would be extremley difficult without some source.

tho if you know a lot of C+ you could feck about with in textpad.

Well, the compiled program(typically about 2 megabytes) exists as machine code, so I would have to decompile before I could do anything, regardless of language.

I think the language will ultimately depend on the compiler. So really, what I need is both compiler/decompiler

most of that stuff is for people doing text dumps/reinsertion but many of the principles would hold for other types of work.

also if its for genesis games i suggest learning motorola 68000 assembly and lots of it.

more info than you could shake a very large stick at and its nice and technical to.

a copy of ida pro would be the most useful thing you could lay your hands on.

Brilliant, I actually have a copy of Microprocessor Systems Design with the 68000 (HW, SW and interfacing).

Expect another post in about a year

As a matter of interest, what do you play on doing?

I want to try and modify roadrash3 graphics slightly. Or whatever I can manage.

Compiled code doesnt contain any comments, so the decompiled code will be the same. It might be impossible, but I'll probably make a hobby of it over the summer.
