N8 v11 Firmware problem - Bug report
« on: July 19, 2014, 01:56 AM »
I have the Famicom N8, which I love to use on my NESRGB-modded AV Famicom.  Seriously - those two things together are like my eight-year-old self's idea of a technological wet dream.

I was playing my actual Akumajou Densetsu cart (Castlevania III), and I noticed that the bass line seemed pretty heavy.  Not surprising, seeing as the N8 has a different output volume when compared to real carts.  My NESRGB's expansion audio is resistor-modded for my N8, so a little bit of disparity is not unexpected.  I was actually going to pin down the exact difference, wire in another resistor, attach it to a switch, and basically have the expansion audio's volume change dependent upon the position of said switch.  Easy-peasy.

However, I fired up the N8 version of the JP Castlevania III, and I encountered an audio bug I have never heard before on any of the previous revisions:  the bass line and notes from some of the sound channels would play just fine, but the other channels would occasionally stop playing or fade out and be totally absent for a few seconds before fading back in over the bass line.  At least two sound channels are affected by this, as is the noise channel.
Code is sacred to programmers - Krikzz' stuff is the holy grail.  It's literally like asking if you can stick your finger up the Pope's arse.

The best way to learn is to ask questions.  Remember, there are no stupid questions - only stupid people, and stupid people DON'T ASK QUESTIONS.

On a similar note, while the FDS expansion audio is substantially improved, some sounds are still a bit garbled-the speech bubbles in Zelda 2 and the fruit-picking and explosion noises in Doki Doki Panic being the most obviously off. However, since the title screen music for both Zeldas are pitch perfect, I think the issue is limited to a certain portion of the code and/or certain notes.

Strangely enough, I can't seem to replicate it.  Must have been a one-in-a-million issue.  Maybe my N8 was slightly improperly seated or something...
