   on FCEUX, got it to make some sounds, etc.
 
   Some Todos:
-  - I need to add the .byte operator to add data bytes.
   - I need to add the #\<$800 and #\>$800 style operators to select the
     MSB and LSB of immediate values during assembly.
-  - I need to make the text/code/data sections easier to configure, it is 
-    currently set to 0x8000 like NES Prog ROM
-  - I need to add commandline options through the OptionParser library
   - I may make this into a Rubygem
-  - I need to split the project up into one class per file like usual.
   - Maybe I can put some better error messages.
   - I should just make a 6502 CPU emulator probably now too.
+
+ Some new additions:
+  - added .org directive
+  - added .dw directive
+  - added .bytes directive
+  - added .incbin directive
+  - Invented my own iNES header directive that is JSON
+  - Split the project up into separate files per class
+  - Wrote some more unit tests
+  - Added OptionParser for commandline opts
+  - Tested a ROM with Sound output
+  - Tested a ROM that changes background color
+
+I decided that during the first pass of assembly, I should just initialize
+an entire 65535 byte virtual memory images, and write the instructions to
+their correct places, and then after resolving symbols during the second pass,
+I just clip out the Cartridge ROM area and iNES header at the end, works great 
+so far.
+
+Next up I will port some more tutorials that use sprites and use controller input
+and sound all together.
