Thanks blargg.

Yes, my code allows the 'depth' variable to be positive or negative, thus I can use the LFO to do pitch sweeping by setting 'lfoSpeed' to zero and using 'lfoDepth' as a signed offset to be added each frame.

Generating LUTs for Cosine and Exponential Volume Fades

I'm pretty rubbish at maths programming so I was wondering if anyone could write some C code to generate a couple of look-up tables. I need the values from 00 to 0F plotting on both a cosine (S-Curve) and also exponential curve with a range of angles (is it?). The LUTs should be 16 bytes each of cou...

Fast LFO

Been playing around attempting to make the fastest pitch LFO possible. This is my latest version which takes about 4/5th of a scan line. I also need it to be able to handle positive and negative "depth" so that I can use it for pitch sweeping too (set sweep direction in "depth" a...

@tepples: Quick question, are your Python tools compatible with Python 3.x? I'd like to update Python (I'm currently on 2.7) but I'm aware of the situation with non-backwards-compatibility that arose with 3.x onwards.

I grabbed the Python tools from CR and (with minimal fiddling) I was pleasantly surprised that bmp2tiles works pretty nicely with indexed .PNGs. Thanks Tepples :) @clueless: I'll have a look at your stuff too. One thing that puts me off from the description is that you're outputting as assembly. Wou...

Re: NES Graphic Converters

I know he was planning to update some of those tools to Python (was it?) but I don't know if he got around to doing that. Inside the distribution of Concentration Room is a converter that uses Python Imaging Library . Alternatively, surely someone could write one? A plain-old C/C++ cross platform c...

NES Graphic Converters

I normally just use YY-CHR as it's quick and easy for doing simple stuff but I really would like to make my graphics/fonts in a more modern way (there are plenty of 'pixel editors' out there these days). However, conversion of the graphics files to a NES format seems to still leave a lot to be desir...

Thanks for updating us. This should go on the Wiki somewhere. So this thing does 60 FPS correctly, without interlace artifacts or anything? I've not recorded anything yet (I only want to use it as a picture-in-picture monitor for my NES) but I can do some tests if it would be useful. Any suggestions?

Well, I have success! :)

Bought one of these: http://www.video-2-pc.co.uk/

And it works perfectly. Highly recommended, if you're in the market for such a device/software.

On the page is says it works with any composite video source. I'd contact the company, and if they can't help, return the product. Emailed. I found another product called Video-2-Mac. It seems the hardware supports proper capture of a LDTV signal but only via a PC-only bit of software called Dscale...

What doesn't work exactly? Does the image have color or sync problems or there's no image at all? All capture devices I have worked with required me to select the video standard from several variations of PAL and NTSC. The picture seems to freeze and most often the sync will be off (picture has rol...

US NES - video output format?

I've bought a USB video capture device for my Mac so that I can do some video capturing from my US NES. However, the two don't seem to want to play nice together. On the device (Blackmagic Video Recorder) you have the option of Component, Composite or S-Video inputs but none seem to work with the NE...

Anyone else had this problem? I've not but I've had an NTRQ user contact me to say DCM had stopped working on his PowerPak (using NTRQ and some games). I'm waiting to hear back as to whether he's using 1.34 mappers.

What's the official problem/fix?

@neilbaldwin and koitsu Are you by chance running Vista or Windows7? No. I run Windows XP SP3. You're not going to get me to "mess around" with random Visual Basic runtimes and other crap either. Sorry, I'm a total hard-ass about it; I Just Don't Do That. That's my own fault/problem/issue...
