Re: Request analysis of my glitchy PPU implementation

I agree that it is probably more MMC1 related, but it looks like you have sprite 0 hit issues too. That could be rooted in the MMC1 issues, however.

Re: Bootgod down?

People may be tempted to try and make backups of the site, I ask that you please do not attempt this simply because it is very taxing on the server, not just bandwidth, but CPU-wise because spiders aren't really "smart" enough to deal with script-based sites like this. Plus, there are measures in p...

Re: Bootgod down?

That's what I am attempting to do. His XML file does not contain everything on his site unfortunately, nor images. You can't make a mirror of the actual site, because he hides all his images behind a PHP script, so scraping is not really a good option, and might take his server down. I'm also not su...

Re: Bootgod down?

It is down and has been for days now. I am working on a site that duplicates much of the functionality and contains most of the data on bootgod's site right now. It will be hosted in a way that is much more reliable. I used bootgod's XML file and ran it through an XSLT processor with my custom XSLT ...

Re: APU Step Timing

By immediate clocking, do you mean on 4017 writes? If so, yes. If you look closely you'll see I just shifted the position of the first column from the original example. I'm counting down CPU cycles to determine when to clock sweep/length/envelope, which seems to be the way things are described on ht...

APU Step Timing

I finished writing an APU last weekend, and during that process I discovered what appears, at least from my perception, to be a discrepancy on the wiki. https://wiki.nesdev.com/w/index.php/APU shows this (which originally comes from apu_ref.txt): mode 0: mode 1: function --------- ----------- ------...

Re: Test NSF Files for Expansion Chips? (Testing Nestopia)

The backporting shouldn't be necessary. Nestopia UE should build on OS X with few modifications (SDL-only mode, no GUI). Unfortunately I am not rich, and therefore don't own a Mac, but someone who does can likely get it to compile with little effort.

Re: Nestopia and Ninja Gaiden/Burai Fighter

This is all you really need to eliminate the Ninja Gaiden (U) moon problem:

Code: Select all

				//if ((readAddress & 0xF000) != 0x4000)
				//	cpu.Peek( readAddress );
I suppose this still qualifies as a hack. At least this way it still passes dma_4016_read.nes.

Re: Nestopia and Ninja Gaiden/Burai Fighter

Interesting how many issues have been discussed in this thread.

I'm understanding the Ninja Gaiden issue quite a bit better now.

perilsensitive, awesome work. I'm trying to digest all of the stuff you've posted still.

I choose ethics and adhering to the license terms set out by the authors of software. If this thread does not make sense: dragon2snow/zxbdragon is a GPL violator.
