I say impossible because one would basically have to build their own sampling hardware from scratch, using much higher than 13.5MHz sampling rate, then write your own software to deal with it, only to downsample the end result to 4:3 720x480 anyway (which I recommend over square pixel 640x480, as yo...

There is no such thing as "pristine and virgin" composite video. I'll say this again (with one caveat at the bottom), lossless compression of analog video is a complete waste of space when you can use high-bitrate I-frame-only MPEG-2 (say, 25Mbps or higher) and retain all the quality. Seriously, tha...

Re: how much power could be used ?
Just to clarify for someone (not you, Kaneda, lol) who may read this but not know - the SMD itself does use the power provided by the MD, it's the FDD attachment that requires its own PSU.KanedaFr wrote:A backup system like the SMD for ex, isn't using the 5V from MD cart port but an external AC adapter...

My capture card allows me to select between 0 IRE and 7.5 IRE. Am I right in assuming I should use 0 IRE? How do I determine which is the best setting to use? A number of ways. You can use the origin of the disc as a starting point. If it's NTSC-JP or PAL, you'll want 0 IRE. If it's NTSC-US, you'll...

I still maintain there is absolutely no need for lossless video here, at least not as an end result. This is baseband analog composite NTSC and inherently full of artifacts that were not intended to be there, but were only there as an inherent flaw of the technology used to store them. LD is limited...

Using audio output is genius, though I don't know how much accurate the final dump can be this way (also depends on each console sound chip I guess). Yeah, it mostly depends on dumping speed (hence why the 2400 and 5200bps rates are problematic sometimes on the NES). It uses the KCS standard for st...

New idea for a cart dumper, would it be useful?
I was reading over at NESDev, and I saw where Chris Covell had released a dumping tool that only requires a non-copier way to run the dumping software on the system (dev cart, flash cart, etc) and an audio cable. It's called TapeDump . It works be loading the dumping software into RAM, revolving on ...

If we can decode it at all in software, which we must be able to do eventually, we can then convert it into a lossless video format, for fast and easy playback on a computer, with much better picture quality than a rip of the analog video stream, all the while, keeping the original video data aroun...

So has there been any further thought to the video format to be used? I just want to make sure you don't go the lossless route, it's useless for analog video and will just bloat the file size (since the composite video is already degraded, there's no sense in preserving those degradations loslessly)...

Ugh, DOS. Someone needs to make a third-party NTVDM for 64-bit Windows... Not to be confused DOS and console. For example, FAR is console programm but not DOS. It's WIN32 application. And yes, console programms are small, fast and simple. And they do not stink mice. :3 Oh, I agree, I love a good co...

Increasing scroll values scrolls UP and RIGHT. Decreasing them scrolls DOWN and LEFT. If your values are getting written to VSRAM properly, then you're scrolling lines up instead of down. Each scanline's value needs to basically be the offset between the actual scanline, and the scanline to be displ...
