I want to disassemble a game "RAINBOW ". It's Mapper 2 and have no CHR,just 128K program rom. So I want to get its CHR date too.
Who could give me an advice or tel me what tool I can use.
Thank you.

I'd break the game down into it's $4000 banks, then put each one through a tile layer to try to spot character data manually for reference. Then would disassemble each combination of banks (0+7,1+7,2+7,3+7,4+7,5+7 and 6+7 with NESRev (need to edit source code for games starting at $8000.)

OK Thank you. I trying now..
But why you disassemble banks 0+7,1+7,2+7,3+7... Because changeing bank is done only in bank 7 ,yes?
I will download NESRev and do it.

And I use "YY-chr" to try to spot character data,but it's hard...I don't know where are the character.

7 because it's a constant bank, banks 0-6 are swapped. You don't need to keep disassembling bank 7 but if you use a modified NESRev, you need a 32k image for the correct offsets so you might as well.

Could you give me the disassemble tool "NESREV"，I can not download it.

I'm not sure how to use java source though.

It must be compiled, I had trouble compiling it with JBuilder but a friend didn't so I just got it off him heh

I found JAVA source too,but don't know how to compile.
Is there Other good disassemble tools recommendable?

Yeah, try Hyde's disassembler:

I haven't used it much, but it's output that I've seen is excellent and even assembled OK.

You could also try Interactive Disassembler, there's a free version of it that supports 6502. It's pretty good too.
