Don't think so. Where ya lookin'?

If it's before the "sbc #$0c" it's deliberate, the carry is set after the BCC instruction.

No problem.

From what I've been reading about FT, it should be easy enough to create a "pitch envelope" and feed in similar values to the ones I listed.

I thought I'd have a go at making it in Nijuu. I don't have SFX so I made a (large) drum to achieve a similar effect. http://dutycyclegenerator.com/sound/explosion.mp3 Here's a copy-n-paste from Nijuu. "DRUM2" is the just name of the drum sound. "DRUM_D" means use voice D (noise)...

I captured the audio and put it into a sound editor. Then screen grabbed that to highlight different sections. http://farm3.static.flickr.com/2458/3674238125_579fce9519_o.png The red section is a few frames of noise starting at low pitch and rising slightly. So maybe 0F,0E,0D,0C. Then a pause of a f...

Ah, I figured out a bigger step size by using the upper 2 bits of the fraction calculation as the number to add to the root note (shifted right the appropriate number of time, of course); PITCH_UP lda NOTE_FRACTION clc adc #$18 ;add pitch offset (value is test number) sta NOTE_FRACTION cmp #$20 ;exc...

I don't know if this is a suggestion or not, I always figured it was a case where if I want it I'll have to write it myself, but just thought I'd say that if in Nijuu there's an easy way to write microtonal music, I would try it out for that. Quarter-tones would be fine. That may sound obscure, but...

An older thread discussing pitch tables and (I think it was Bregalad) the idea of having intermediate steps in between each note value (a figure of 31 steps in between was discussed) got me thinking along those lines. But for me that would generate a ridiculously large look-up table (80 notes x 32 ...

Hoping for some inspiration here so feel free to chip in (sorry) with any ideas. Currently I have a full note table in Nijuu - 80-or-so 16 bit entries, the index into the table being the current note number. Familiar stuff I'm sure. Couple of things bug me with this approach though; 1 - Pitch sweepi...

Perfect, I'm in the UK!

This is not working out anywhere near as smoothly as I (with hindsight, naively) thought....

Does your screen accept ntsc? Also did you use AV cables? Like those that come with snes? Rgb ones (scart) won't work with the av famicom. NSTC - yes. SNES cable - yes. Trouble is, I need to wait until tomorrow before I can get someone to take it apart and assess the damage. Also, more cause for wo...

Crap....you did it? Ouch, well it might just be the 7805 regulator that blew up. I DID warn you on irc though. Stil too bad :-( And I did tell you I was cursed with those sorts of things :) In actual fact, I got it the correct way first time but the screen stayed black so I swapped the polarity, th...

Oh no

Thanks, everyone, for the input. To clarify, yes I just want to be able to listen to my music on hardware - I don't need anything more fancy than that, really. And I'm not particularly interested in expansion audio so I'm not concerned with that aspect at all. Oh, and does anyone know what might hap...

Thanks Banshaku.

Is there any merit in picking up a NTSC NES to use with PowerPak (Lite) + CopyNES? Or will it just not work with my computer anyway?
