It should be noted that DKC was released on Game Boy Color in 2000-ish. Since the NES and GBC have similar-looking graphics, I think an NES DKC would look just like the GBC version.

Now I am getting a bit of a better understanding of how these PCM-based speech engines work. I've got the jist of how the sample playback works, but it is animating the character's mouth that I am wondering about. Of course, accurate lip synching is not an overall necessity, considering that the sam...

Let me see if I got this straight--

So in Hide & Speak (and Sesame Street Countdown) the audio is just PCM--no "D."

Big Bird's hide and speak did not use DMC. It used a number of compressed audio samples. There was no speech snythesis there. I thought the DPCM was a sample-playback system. I should have done more research, though. I was playing Hide & Speak on FCEUX and the voice's volume was controlled by t...

Hello. I got most of my programming skills from Nerdy Nights. ( http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=7155 ) However, in looking at the sound tutorials, I notice there is no DPCM tutorial. Can anyone recommend a good DPCM tutorial, that would implement Nerdy Nights' logi...

I solved it myself! Just needed to do a little research. I'd still love to hear your methods, though.

Hello. I am thinking of starting a business that replaces the Save RAM batteries in ANY cartridge based system...not just NES but also SNES, all the Game Boys, N64, Genesis, you name it. I'd also install battery holders (when possible) to facilitate easy replacement of the battery in future. The ide...

@3gengames...

I'll re-read the tutorial and try it again myself, then if I need help I'll let you know.

UPDATE: OK, how do I address the PPU RAM beyond $FF in the LoadBackgroundLoop?

You you see all zeros, after you set the PPU address with two $2006 writes, you store the number of the tile you want, make sure the number you want is right. Code please? LoadBackground: LDA $2002 ; read PPU status to reset the high/low latch LDA #$20 STA $2006 ; write the high byte of $2000 addre...

Hello. I am in need of some help following Nerdy Nights' Background tutorial . In attempting to fill in background tiles 5 thru 19 (where mario would be standing) with "all sky," I experienced a problem. I (supposedly) coded the nametables right, but I still see zeroes in the rows that I c...
