by looking at registers and frequency (FFT) data Frequency data? Under what scenario might the following similiar approach fail: For each frame, make a snapshot of both CPU RAM and hardware registers --- then compare each new frame's snapshot with all previous ones. If a match has been found (all v...

That would be 1/3 color clock worth of shift. That's what I thought too, but it doesn't look right. Maybe I'm doing something else wrong. If you want to take a look: even field odd field Obviously you need to look at them in 60 Hz succession... aside from the colors (I'm just guessing the four luma...

Dot crawl has absolutely nothing to do with the aspect ratio. Instead, the dot crawl is synchronized to color burst. ... relative to the NES' pixel clock, yes. I already have it finished except for the exact color burst shift between odd/even fields. :) What you're seeing is that the NES might not ...

That probably is a very good solution for the aspect ratio problem. Unfortunately, I need to get this right for another reason: unless I get the horizontal resolution properly nailed down, I won't get the composite dot crawl pattern right. I just fiddled around with the horizontal centering of my So...

A lot of consumer and even prosumer video capture devices are not close to CCIR 601 compliant. Closer than that page you linked to certainly. And again, those screenshots are only an illustration of the relevant point, that the active horizontal area is 720 pixels wide --- just as the ITU 601 state...

The 720 pixel area sampled under CCIR 601 is wider than the actual picture area in order to provide enough headroom on the sides to capture the whole scanline even if the sync signal is wobbly. No. The 720 pixel area is the "active area". The "headroom" you mention is the "back porch" and the "fron...

CCIR specifies that the NTSC picture area is 176 color clocks wide by 240 pixels tall What specific document would that be? The CCIR 601 recommendation, now renamed to ITU-R BT.601-05 (recent version), makes no mention of 176 color clocks; it mentions 720 horizontal samples for the luminance and 36...

Overscan/HBlank

It is known that there are 340/341 PPU cycles each scanline, with 256 cycles producing rendered pixels, and 84/85 cycles "horizontal blanking". If you look at video-captured screenshots, you'll see there's some picture visible to the left and to the right of the 256 rendered pixels (overscan), which...

That game has already been nsf'd --- "Bananan Ouji no Daibouken", which is the original Japanese version.

That's a music code bug, not "alternate versions". Then again, since someone already did a Game Genie'd Megaman rip, I'm sure you'll get your wish sooner or later. :)

Does anyone know exactly what said hardware defect was technically? The reports I read just talk about "rampant freezing".

You know, I never noticed that the Vs. ending was actually different than the regular one. I just listened to the first notes and thought they were the same. Silly me! The faster versions are omitted on purpose. I interpreted the "unused" game over theme as an artifact rather than a purposeful but n...

I searched said list for your rips and only San Guo Zan came up If you're talking about "San Guo Zhi - Ying Jie Zhan", that's a different San Guo Zhi.

Has anybody ever ripped the extra songs in SMB2J and Vs. SMB? SMB2J has a FDS-enhanced version of the ending music, Vs. SMB has a Name Entry music. I ripped those some time ago but didn't post them because I thought somebody else already had. Apparently not so, since I can't find them anywhere. I ha...
