Wow what an upgrade over the original intellivision version. Very nice.

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!

Exactly right. 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).
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?

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.
