Don't get me wrong. I use labels/variables for my code. Self-commenting code is the best kind after all but I was asking more for the sake of learning and understanding how things work rather than how I wish to code.

Once again, thank you for the help. I am sorry I wasn't all that clear about what I was seeking Dwedit.

What I mean with 'pure 6502' was just the bare mnemonics/operands i.e. LDA $0200 As opposed to LDA Some_Label I didn't mean writing the actual opcodes and values. Addresses $0000-$01FF have special meanings, but you can put variables in unused parts of those. How exactly would one know where the unu...

Tepples has what I was seeking. So correct me if I'm wrong here, as far as writing to the RAM goes, you can write anywhere between $0000-$0800 which would be the NES' 2K worth of RAM? If I have WRAM in my game, then I could also use $6000-$8000? Am I in the ballpark here? Anything missing?

Perhaps I didn't word my question correctly? What I am trying to say is, that is how NESASM3 allows a person to code access to the RAM via the use of a built-in macro.

Using pure 6502 assembly, how would one write the code to access addresses in the RAM?

I have learned a majority of my 6502 programming from Nerdy Nights which uses the NESASM3 compiler. NESASM3 uses .rsset to start the RAM location and .rs to set aside locations: .rsset $0000 Var .rs 1 ; Reserve one byte ($0000) This is NESASM's way of working with RAM via a macro. What is the 6502 w...

Isn't using a PowerPak too easy?

So what is the premise of your game you have in the works? Is it just a concept thing you are working on or is this a new homebrew game in the works?

Interesting video blog. I'm gonna have to keep checking for updates. By the way, what IDE are you using for your coding?

Use DOSBox for running your 16 bit software.

0200: A9 00 START: LDA #0 0202: 85 00 STA PILEN 0204: 18 CLC 0205: 20 00 01 NXKEY: JSR GETKEY 0208: C9 0F CMP #15 020A: D0 05 BNE NXTST 020C: 20 87 02 JSR BEEP3 020F: 90 EF BCC START 0211: C9 0E NXTST: CMP #14 The part that has me confused is line 6. BNE's opcode is D0 so no problem there, but what...

I knew if I didn't extrapolate I would be questioned. I also probably should have worded that a bit better. I do not like developing games because we are surrounded by these visual masterpieces. If I were to set out to make a shooter game, no matter how long I work at it, it will always come up shor...

I'm not so much aiming to write a fully accurate emulator. I'm just doing this to screw around and get a hopefully get a better understanding of the NES. I have a C++/Java background. I have not written any games simply for the fact that game development is one of those things I hate (ironically eno...

I can't find a thing on the site. I might try my hand at an emulator just for the sake of trying. Do ya'll have anything that I can read as a starting off point?

Kasumi, I swear everytime you respond to one of my threads I learn something new about efficiency. Using a BEQ in place of JMP is so blatantly obvious that I just completely don't see it. Truth be told that just gave me several ideas on ways I could make my code just a little better.
