One of the riffs in Track 2 reminded me of a riff from Mega Man 9.

Then what do the "TV games" use? They usually use either microcontrollers or programmable logic to render video. Some use actual ASICs of old consoles/computers (C64 DTV, Genesis TV games). Actually, I did some searching, and it turns out that there is an actual old-school-console-esque chip for sa...

some Video processing chip etc are not common practice anymore (or hard to find)? Yup pretty much. All graphics chips from the 80s with NES-like capabilities are no longer in production. It is possible though to find certain chips like the 6845 and 6847 for sale at some online stores, though they a...

But there are eight programmable 32-bit CPU cores that run at up to 20 MIPS And what's 8-bit about that? It's not 8-bit, but it's not a super powerful 3D console with texture mapped polygons either. It sounds really powerful on paper, but trust me, it's not as powerful as it sounds. It's somewhere ...

There's a development scene about new 8-bit consoles: http://www.xgamestation.com/phpbb/

It's run by the same guy that wrote Tricks of the Windows Game Programming Gurus.

And About 6502 books: They are hard to buy nowadays for me. If there is one gripe about them, The price is ranging from $100-$200.
You can read really good stuff about the 6502 online for free: link, link, link, and link.

There's no reason you can't have it on Garage Cart 2 and submit it to the Mini Game Compo.

From what I've heard, audio data ($40xx registers) is usually buffered in RAM, and changes in audio are written to the buffer from least priority to greatest priority, and then the buffer is written to the actual registers. It makes it easy to do sound effects with background music this way. In the ...

You should add some AI, convert the mapper to CHR-RAM, and submit this to the Mini Game Compo.

When I've played this in Nestopia 1.40 I've had it occasionally pause without the Start button being pressed. Has anyone else have this happen to them? It could be the DMC glitch.

Actually if you watch the original movie, when it shows the view from the terminator's eyes, you can see that the terminator is apparently running (or perhaps disassembling) some 6502 code.
And here's what he's running.

Most of the songs are listed as having been remade by Snowbro, so maybe he has worked on it. The "Contact Us" page lists Kent Hansen and Andreas Pedersen. Does anyone know who they are?

This document (search for "Frame rendering details") has a detailed description of the scanlines rendered during a frame. The reason that a lot of documents have the NTSC resolution as 224 scanlines is that most NTSC TVs are unable to display the full 240 scanlines.

Good job, and thanks for the link. I only see one problem: A game that scrolls in all four directions will often have artifacts on one side of the screen because the NES doesn't have enough VRAM to keep the "seam" where new map data is loaded clean. To hide this, a game such as Jurassic Park might d...
