I have been reading through the emulator in Javascript walkthrough. It does a good job at explaining the basics. I'm not very far into development, still trying to understand the basics of the CPU. The manual and opcode chart you posted will help out a lot with that.

Thanks for the tip about the CPU instructions. I did notice that, but when looking through the Javascript code there was a one to one relationship with opcodes to instructions. Wasn't sure why the person went that way, maybe because it was easier? Either way I will keep that in mind and try to do code reuse!

Test ROMs are amazing! I have been playing around with a few ROMs I have and they all seem very complicated. This should make it easier to determine if I'm on the right track or not.

With the little code I have written, 90% of it is Printf to the screen to see what is going on :).

I do want to share with you this other tutorial that I found [1]. It is similar to the Javascript one, but it goes into way more detail on some parts.

Thanks very much for all the help! I have a lot of reading to do this weekend!
