-Disassembler for 6502 processors
+Disassembler for 6502 processors.

+# Features
+* Simple command-line interface
+* Single file, ANSI C source
+* Annotation for addresses of Nintendo Entertainment System (NES) system registers
+* Cycle-counting output
+* Machine code display inline with the disassembly
+
+# History tidbit
+The original 1.0 version of dcc6502 was written overnight on Christmas eve
+1998. At the time, I (Tennessee Carmel-Veilleux) was a 16-year-old NES
+hacker learning 6502 assembly. Of course, as many teenagers are, I was
+a bit arrogant and really thought my code was pretty hot back then :)
+Fast-forward 15 years and I'm a grown-up engineer who is quite a bit more
+humble about his code. Looking back, I think the tool did the job, but
+obviously, 15 years of experience later, I would have made it quite a
+bit cleaner. The disassembler has floated online on miscalleanous NES
+development sites since 1998. I decided to put it on github starting at
+version 1.4 and I will be cleaning-up the code over until version 2.0. 
+
+This disassembler has made the rounds and has been used for a lot of
+different purposes by many different people over the years. Hopefully
+it will continue to be useful going forward.
