I'm getting really confused as to how backgrounds work and how they're related to name tables and attribute tables and where they're loaded and how to make them! I have some vague ideas, but nothing I can implement in code because I don't really know how it all fits together. Are there a pertinent s...

Thanks guys I got it working! I'll be sure to check out CA65. Sublime Text doesn't seem to have anymore problems with non-breaking spaces either.

I'm using Sublime Text 2 right now and it's probably encoding it improperly. Do I just use ASCII then? There's something that will be a problem when the program does assemble: even though there's a comment mentioning it, you're doing nothing to actually put the vector table at $FFFA-$FFFF. The way i...

Hey, so I made a post ages ago concerning NES programming never really got off the ground because I didn't know anything about computer architecture, haha. But recently I've been thinking about getting back at it as a hobby. Anyway I tried a intro tutorial to but I can't get this code to work on NES...

Yet more questions... How exactly does the stack pointer work and what does it do? I'm getting different definitions from different docs. While looking through some homebrewed games for the NES I'm noticing headers, ".org" seems to be common to a lot of them. The 6502 stuff I'm reading doe...

I'm having trouble understanding how the program counter and relative addressing works in relation with JMP and the various branch functions. Any help, is again appreciated.

Many thanks.

So if I understand correctly, signed and unsigned numbers are interpreted by you and determined with the N and C flags, right?

Pretty much understanding the other stuff. Any source I can get my hands on (probably help a lot in the learning process)?

Thanks for the explanations.

Some questions now... How big can A be? For instance if I wanted to perform larger (> 8-bits) calculations. I'm kind of hazy on how 6502 handles signed and unsigned numbers, explanation would be helpful. I'm getting the impression that it only has signed ones. How do you end a branch? The examples I...

OK, so I got this crazy ambition to write my own NES game (I love the NES and have some light programming experience), problem being I don't know where to go. I basically have this so far: - Need to learn 6502 ASM - Need to learn NES hardware, processors, etc. I've been to nesdev.com, but I don't ha...
