Zoop to the NES!

Zoop NES

Back when the SNES was popular, I noticed reading NP and saying to myself "most of these SNES games are 8MB or under, they could be done on the NES!" Well, now I know the difference between SNES and NES, but one game that I thought would actually be doable on the NES is Zoop. Fast-forward years later after successfully programming 2600 and Virtual Boy games. I figured if I can program for the Virtual Boy, I could program for the NES. One considerable drawback is I need to learn ASM programming. But here's the hitch: I learn by tweaking examples. And one of the guys on PVB says not to put something in your program that you don't know what it does. Of course, I don't know what ANYTHING does in asm. I have been trying to tweak an example to show a screen of one color in the NES, but I just can't do it. It has to do with the line that says " LDA #%10000000 ;intensify blues." All I know that the semi colon acts like an REM does in bB, so I could put anything after the semicolon. So what I need to do is make the screen display my CHR file in an NES program. All this and I still don't know what a CHR file is. And it took some length to even get the CHR file. After on my new computer I got some stupid message saying that the command prompt doesn't support full-screen mode, I had to use my old computer to get it and put it on my new computer. After making an ASM file about half-a-year ago, here is a link to it in all its not-working glory. Of course, any help or tips, or examples to put CHR files into an ASM file would be greatly appreciated.
