Re: SPC700 Opcode Matrix

That's not a bad idea, actually. I actually haven't seen matrixes for the majority, if not all of the assembly languages... so I would be interested in seeing one for the SPC700.

Re: Understanding FIR Filtering

I have some fun parameters that I've done before. I've used these all usually with -128 feedback:

64, 32, 16, 8, 4, 2, 1, 0

64, 0, 0, 0, 0, 0, 0, -63

Of course the user can also define them. I just simply find out which ones work well for me just by directly fooling around with the values.

Re: SPC inverse Voice Phase with negative volume MSb set

This is the best use I have for a phase inversion...

- Channel 1 plays a sample.
- Channel 2 plays the same sample at the same time, but with phase inversed and the pitch very slightly toned down.

If Channel 2's pitch remains the same, the result should be no sound because the sound cancels out.

Re: 2A03 Puritans compilation album

Hello. I am one of the composers from the soundtrack. :wink: With a couple of exceptions, the majority of the tracks were made in Famitracker. The exceptions are TQ-Jam's (which is done with MML) and my song, which was made with Schism Tracker and then converted to .nsf file via mukunda's it2nsf. Th...

Re: SNES Tracker

Hey, bazz! It's your old pal KungFuFurby! :D I had an idea on how a tracker could work on the SNES in a variety of different ways (one would just simply stream the note data... in this fashion, it's NES-style composing all over again, since you're limited to the SNES's clock unless you wanted to get...

Re: no$sns v1.5 released

I've been using your emulator (however, I use a Windows computer only in conjunction with my Mac computer because I am able to produce a working SNES game on the Mac... graphics included.) for debugging purposes. I also use laevateinn (mainly for its CPU debugger feature since I can still execute co...

Re: SPC sound driver algorithm

I take my conversions very carefully: I do sample chopping and quality reduction right off the bat. Without any actual note data (and practically the entire RAM for sample data), the SPC700 can take around 100,000 samples. Another one that I think of is sample offset. That should be possible as long...

Re: I finally made something decent with famitracker

I recall being able to redefine the keys when I was using my laptop (which is indeed the Windows computer I use)... and that came in handy for me to make it a bit more convienient. However, FamiTracker is not my regularly used tracker since I'm on my Mac much more often.

Re: MIDI player for the SPC, any interest ?

Yeah, the worst part about doing it in real-time is you're at the mercy of the SNES's clock speed, which is 60hz or 50hz, depending on NTSC and PAL settings. However, with IRQs (using the vertical line count as a reference), perhaps you can speed it up at the expense of losing some time to process t...

Re: MIDI player for the SPC, any interest ?

I'm going to completely wing it, but perhaps MIDI is better used for real-time note streaming? Also, even if you used MIDI for real-time note data streaming, I myself can do calculation on how large a sample can be on average if you wanted to load all of the GM instruments... here's how large the co...

Re: MIDI player for the SPC, any interest ?

For Star Ocean and Tales of Phantasia, chances are they used a MIDI to their own custom music format converter. I've only seen a few games actually use raw MIDI files... the rest, if they did use them in the first place, straight out converted them to a custom music format. Hey, I actually had an id...

Re: MIDI player for the SPC, any interest ?

Cute Angela's source contains a MIDI to music for Paul Lay's Sound Driver converter... and for those of you curious, I have seen MIDI used in two ways in actual SNES games. Games composed by Michel Winogradoff stores the MIDI data and samples in there all at once (obviously switching samples and wha...

Re: New game - Classic Kong

I kinda recognize this as a NES to SNES port... it's somewhat justified for a two megabit game, as a lot of the memory is used up by all of the data combined.

I'll be looking for this... if it survives past the Parodius closing (I think it will... just that I need to make sure to check the URLs).

Until then... Sayonara, Parodius. :(
