This memory area again, is large enough to hold the contents for 8 sprites. When the counter equals 0, the pattern table data in the shift registers will start to serialize 1 shift per clock. Before this time, or 8 clocks after, consider the outputs of the serializers for each stage to be 0 transparency. Otherwise, priority is passed to the next serializer in the sprite buffer memory, and the test for non-transparency is made again the primary object present status will always be passed to the multiplexer as false in this case.
This is done until the last 8th stage is reached, when the object data is passed through unconditionally. Keep in mind that this whole process occurs every clock cycle hardware is used to determine priority instantly. Pattern table bitmap 0 for next scanline - 4.

Pattern table bitmap 1 for next scanline - - This process is repeated 2 times. These fetches initialize the internal playfield pixel pipelines 2- bit shift registers with valid bitmap data. The rest of tiles Name table byte - - - I'm unclear of the reason why this particular access to memory is made. The name table address that is accessed 2 times in a row here, is also the same nametable address that points to the 3rd tile to be rendered on the screen or basically, the first name table address that will be accessed when the PPU is fetching playfield data on the next scanline.
On every odd frame, this scanline is only cycles the dead cycle at the end is removed. This is done to cause a shift in the NTSC colorburst phase. This means that if a single pixel resides on a scanline with a color different to those surrounding it, the pixel will probably be misrepresented on the screen, sometimes appearing faintly. This is why when you play games with detailed background graphics, the background seems to flicker a bit.

Once you start scrolling the screen however, it seems as if some pixels become invisible; this is how stationary PPU images would look without this cycle removed from odd frames. Some of Zelda 2's dungeon backgrounds are a good place to see this effect. Having said that, I guess Nintendo wanted to provide an "easy-to-use" method of generating special image effects, without making programmers have to figure out how many clock cycles to program an IRQ counter with a pretty lame excuse for not providing an IRQ counter with CPU clock cycle precision which would have been more useful and versatile.
There are some odd side effects to this scheme of rendering, however. For instance, imagine a low priority object pixel with foreground priority, a high priority object pixel with background priority, and a playfield pixel all coinciding all non-transparent. This means that the playfield pixel should hide the background priority object pixel regardless of object priority , and the foreground priority object should appear atop the PF pixel.

Go into airman's stage. First, jump into the energy bar, just to confirm that megaman's sprite is of a higher priority than the energy bar's. Now, get to the second half of the stage, where the clouds cover the energy bar. The energy bar will be ontop of the clouds, but megaman will be behind them. Now, look what happens when you jump into the energy bar here But this kind of implementation is more suited for an integrated circuit, since this would require dozens of discrete logic chips.
The caveat here is that pixel pipelines i. With a memory device capable of a Generally, this would be very useful for displaying multiple huge objects on the screen- without ever having to worry about annoying flicker. Because of this, hardware would have to be implemented to decide which palette select value to feed the PPU between 8 horizontally sequential pixels, if they do not all share the same palette select value. The on-screen results of this may not be too flattering sometimes, but this is a small price to pay to do some neat graphical tricks on the NES.
The MMC5 was the only device that came close, and it's only selling features were the single-tile color area, and the vertical split screen mode which I don't think any game ever used. Considering the amount of pins the MMC5 had, and number of gates they put in it just for the EXRAM which was 1K bytes , they could've put some really useful graphics hardware inside there instead. The cart was never released, but from what I've read, it was going to use some sort of frame buffer, and a Z80 CPU to do the graphical rendering.
It had been rumored that the game had 3D graphics or at least 2. If so and the game was actually good , prehaps it would have raised a few eyebrows in the industry, and inspired Nintendo to develop a new MMC chip with similar capabilities, in order to keep the NES in it's profit margin for another few years and allow it to compete somewhat with the more advanced systems of the time. Each licensee is addressed as "you". I've also added some "BEOS" ifdefs.
Names you didn't get to pick to have are so troublesome. Sorry for any confusion. See the documentation for more details. For fun, "starmen. Documentation updated. It calls Sleep 0 in its wait loop. I also added the Scale3x scaler. It's still not right. Also, SDL 1. Ah well. This eliminates the X-offset hack I made earlier. Fixes many CodeMasters games. Maybe in SDL 2. Fixes Kaiketsu Yanchamaru 3.

Does it break anything? Are there others? I still need to think about it. I need to fix them. Screw speed. I think. It is not completed yet, though. Set the default xscale for windowed mode to 2. Fixes "Bee 52". I must see if it breaks anything. Fixes that crazy Sayoonara demo by Chris Covell. At least it tastes good Information taken from virtuanes. It should support streaming pcm nsfs now Added a message window.
Needs special keyboard emulation. Silly game. Rahmen Man. Needed for compiling under BeOS. I'm not sure if this is correct I should clean it up later. Fixes BattleToads Increased the refresh rate of video mode 3 to hz.
It's x at a refresh rate of hz. I'm still not sure who made it, though. Fixed the bug in "input. New kevtris' brain is always good. It still needs a lot of work. Removed netplay. I still need to test it on various other sound cards, though. Fixes a UNIF loading problem. Same credits as below. I traced it back to. I'll change the Windows port reference later. The code is ugly I don't know if this is right I really don't care More info later This is an ongoing process This should fix network play on the Windows port. I also added a volume control. All clipping ugh is done internally now. I have no idea if what I did is correct.
This speeds up NSF playback considerably. This appears to fix "Stunt Buggies". Thanks to rinao for the information. Thanks to Mark K. Fixes "Tenchi o Kurau 2". This bug only showed up on the Windows port, though. This is useful for some digital joysticks. Diff output truncated at characters.
This was sent by the SourceForge. The source code has also been released. I had wanted to clean up the code much more, but I also wanted to get the code released. The next source code release should be much cleaner. Knibbs for the information. This is the last build for DOS. It's quite different from previous versions for Windows. Source code and other ports will be released in a few weeks when I have the time to rewrite the driver code for other platforms. It resulted from a very stupid programming error on a large scale.

I'd be interested in hearing if anyone else did, though! What the heck is with those requirements? The only went up to 40 MHz. The more you know The app bundle should include all the required dependencies, so it should work out of the box. Let me know if something's not working, and I'll do what I can to fix it!
