Help with MX flash chip!!!

I have a programmable flash chip made by MX
no. is 29F004TPC-12
Getting the spec for this wasn't easy and a couple of companies make the same type.
Since my programmer was able to program these, I thought I'll fiddle with it, me be being at learning programming stage and all..
Anyways, I was able to read the chip and could save the hex plus bin file, but since none of them make any sense in text format, I was wondering is there is any of seeing what the real code would look like.
I got this idea by seeing and trying a disassembler for PIC to MPASM.
I disassembled a hex file even though I did have original ASM . I tried to see that if it was possible and it worked. Both the files looks the same, but I can't do any thing with the hex that was in the MX chip.
The reason was there was no .inc file to begin with and I donno which type of software was used for this chip.

Does any of you have any insight on these chips and what kind of tool is use to write codes for it.
How can I get them and any tutorial on it would be of great help.

Thanks
