Rev Posted May 7, 2012 Share Posted May 7, 2012 Just a quick video I uploaded of DK Arcade that I got last week. I will upload another one showing off the voices in the game very soon. http://youtu.be/oo_7AXZZZUs Quote Link to comment Share on other sites More sharing options...

Carl Mueller Jr Posted May 8, 2012 Share Posted May 8, 2012 (edited) http://www.youtube.com/watch?v=bybW5QR1BBM&feature=relmfu Why does YouTube have such a problem with playing videos at 60 FPS? The video is captured from an Intellivision II with composite output. The original video looks great, and there are no problems with disappearing objects. Obviously YouTube is downgrading the frame rate in some way, and we have the disappearing object problem. This is probably how the game appears on some HDTVs without using the 30 FPS code. If someone knows how I can fix this problem … please let me know! Edited May 8, 2012 by Carl Mueller Jr Quote Link to comment Share on other sites More sharing options...
RedRaider Posted May 8, 2012 Share Posted May 8, 2012 Wow, I like this rendition of the game on Intellivision. Need to pick up a copy of this. Quote Link to comment Share on other sites More sharing options...

If someone knows how I can fix this problem … please let me know! I love that ape "grunt" sound in the introduction and at the end of a level. It is the one thing I thought was conspicuously missing from Donkey Kong Arcade--just because everything else was so perfectly reproduced. I noticed that the ape "grunt" at the end of the first level happens way later than it is supposed to. It's supposed to go right after the jingle plays. I also noticed that the flames stopped animating during it. I guess it is some sort of technical restriction that requires the full attention of the CPU to play that sound effect, and so you wait for the ape to leave the screen, right? -dZ.

Playing a digital sample through the Intellivision's PSG requires the full attention of the CPU (almost). I'm attempting to play the samples back at about 11 kHz, the original sampling rate. At the same time, I'm unpacking individual bits and implementing the delta modulation decoding to produce a sample, which in turn is used as an index into a lookup table of volume values for the PSG's three channels (approximating the sample). Most people blank the screen as well, because the VBLANK and STIC cycle stealing have an affect on the output. Fortunately, the samples are scratchy enough in the first place that they don't suffer much from being played during active display. But yeah, that's exactly why I wait for DK to exit the screen before sounding the grunt. You haven't heard it together with the girl's "help!"… you might like it even better! :-) Carl Quote Link to comment Share on other sites More sharing options...

+thegoldenband Posted May 9, 2012 Share Posted May 9, 2012 IIRC, Youtube doesn't support 60fps video -- everything is automatically downsampled to 30fps. I've read that Nicovideo (a Japanese site that's popular for gaming videos) supports 60fps. Every so often I marvel at the fact that most online video content is delivered at a lower quality, and with a far higher CPU load, than what was routinely possible 8-10 years ago! True, you don't have to wait for a huge file to download this way, but still, it's ridiculous. Quote Link to comment Share on other sites More sharing options...

Welcome to the "webification" of all technology, where making a web browser do half the things, half as good as we did 10 years ago is considered innovation. Hurray for progress. -dZ.
