What an outstanding link. I suck in DSP, now i have a good resource.
Thnks!!

(sin(n·x)÷(n·x) )

I don't understand the above func/formula.
1 - Is "n" the sample?
2 - What about "x"?
3 - I take the sin() when?

Sorry my poor understanding.

Well, im taking the sound from APU about 32~ cc. So i decided to make a Filterbox for it. This means summing the samples in that "window" (32~ cc) and then dividing it for the cc passed, that is about 32~ cc. And i came with this class: class BoxFilter { float * in_samples; const int size; int sampl...

I changed the key mapping as you said, but i discovered that "Z" and "X" can't work together. That means for example that Mario won't jump as NES B Button (Z in your case) doesn't work well. I don't know if it is a DirectInput8 thing or what. So i used "A" and "S". I algo changed the emulator Name t...

Ok Zepper, i understand a little more now. I tested your IRQ clocking and works as idendtical as mine. (Flinstones game bar keeps shaking, for example) I have a question, i tought that the "check" for A12 should be done in PPU ADDRESS. You are telling me to do it in loopy_t which is the "TEMP" addre...

ANES, do you use ICQ? let's chat! 12292568 1. Well, most games rely on sprite fetching at PPU cycle 260. In other words, when sprite tiles are fetched from PPU $1000, so MMC3 IRQ should be clocked. 2. You must put a check on $2006 writes, watching PPU address. 3. When you get a raise 0->1, there's ...

Oh!! The Pink Floyd's Dark Side of the Moon With Zelda!! That's ok :D Two epic things. Yeah i have checked the wiki so many times. I tought that changing my CPU emulation cycle by cycle would help. As you said is very confusing. I would like to do something like Messen did, but i cant. Then if i tak...

Hi mkwong98. Thanks for your cocerning. I could pass the tests, i don't know what i did. Suppoused i touched something in the source code. Now, it works fine. And i don't know why Windows 10 started with its "smart screen". I know about virus thing, but Chrome detects my "exe" as a potential virus. ...

No help?? Chryst!!

Please be patient with me. It's the first time i try to do this. I know it's a difficult thing to accomplish, so i'm asking for help. I'm trying to catch A12 0->1 and clocking the MMC3 IRQ counter. I pass all MMC3 blargg's test execpt the timing for scanline 0, which throughs me "too soon". My IRQ c...

I write this becouse i'm failing in "Sprite hit order" and "Sprite Edge Timing" Blarggs test. Both fails with error #3.
I really don't understand what is testing those 2 roms.
If someone can explain me what timing roder and edge timing is it will be appreciated.
Thxs.

Sorry, i diidn't realise that there wasn't keyboard support.
I added to it.

Keys are:

Directional: Up,Down,Left,Right
Buttons:
Z -> Select
X -> Start
S -> A Button
A -> B Button

Joystick support exist, altought is some buggy

You have the NES generating a picture at ~60.0985 FPS

But, why they not sync EXACTLY at 60 hz??
Is it an electricity/electronic thing?

Well, it's time see what others can see in my emu. This is my very first release of the new Yanese. Anyway there are a lot of things to do/improve, etc. - Savestates are NOT SUPPORTED - Mapper 0, MMC1 (buggy), MMC3, AOROM, CNROM and UNROM mapper emulation - TV aspect (I use Blargg's code), please te...

I did it!! I don't know how and why by took the emulated cpu to 1776000 mhz.
So now it takes sound every exactly 32 (integer) clocks.

Since there are many variables (cpu speed, sound hz, clocks, etc) the thing seems not to be desyncing sound enymore.

thxs for the help
