I think we can all agree that stack initialization, while not required, is good practice.

One of these days I have got to try my hand at SNES dev. ;-)

Mapper hardware registers can be mapped onto PRG-ROM space in CPU memory because of what it is: read-only memory, with mapper hardware access usually limited to write-only. So, you can read data from a ROM in the same space that you write register values to, because they go to different circuitry.

I actually started working on this a while back, but I've been pretty damn sidetracked...

I don't deny that I could have done certain things better (commenting every line seems to be a common pet peeve) and explained things a bit more in-depth...but what you have to realize is that this was my first ever reverse-engineering work, and it was written back when I was still somewhat wet behi...

Sweet mother of science, I've created a monster.

Or, you know, you could just not disassemble the character rom part of the .NES file, assuming that part exists. As for the other two formats, you're on your own figuring out what's what. Which is kinda the reason why code/data loggers exist in the first place.

That sounds about as practical as writing an emulator for an emulator. In fact, it sounds exactly like that.

It's a wonder more developers did not embrace the potential of 4-screen by simply adding external name table space. :-)

So the current state of documentation is not perfect. How would one go about making it any better? Also, is the current state of documentation really any better for other systems?

You know his topic collides with my question. How the fuck do I move the palette pointers? Like I want more that use the brown pallete, which is like palette $03 I think. I need some solid $03 tiles. Or better yet just tell me how to make the mushroom platforms's tops use palette 03 It sounds like ...

The ONLY way you could possibly modify VRAM (through registers $2006, and $2007) mid-screen is if 1. The VRAM had dual ports and one of them was hooked up to the CPU bus, which is not the case, or 2. If the PPU is not rendering at time of modify. And I'm not sure what's going on in those other games...

Why does it stink? Does it stink because you can't get access to a document that few of us have access to, and you think they're withholding it out of malice, or does it stink because you're too lazy to find the information, which many of us have already made available, or even to ask questions abou...

Very interesting. I had no idea such a port even existed.

We're people with our own ideas and conclusions about things, not sock puppets or well-bribed politicians who say yes to everything. :)

Well, you're mostly correct. I just happen to be a level 25 sock puppet. I bet you guys didn't know that, eh? ;-)
