since your using a tool that doesn't use native SPC700 I can't even comment lol.. but you're not actually setting the FLG, in your case use it to unmute all the channels and disable echo.. in your case you set echo region to 0xFF00 so there's likely 4 bytes occupied there from echo region, that has ...

Check that you have disabled echo in the FLG register...echo can and willl mangle up to 30KB of memory based on the setting of EDL from address specified in ESA. In most cases, the memory occupied is 2KB * EDL, unless EDL is 0, it only occupies 4 bytes from ESA. If that's not the problem, good luck ...

I really love what you're doing here KFF, I just don't have the time to invest in learning about this stuff right now

Code: Select all

	fn = malloc(strlen(argv[0]));
	strcpy(fn, argv[0]);

That's a buffer overflow. Similar cases appear elsewhere in the code.

Fix: malloc(strlen(argv[0])+1);

KungFuFurby is this correct? or is this wavetable synthesis - in which case I recall the term thrown around earlier in this thread, but its fundamentals are above my knowledge levels

KFF, can you please tell me what effect this is? If you tell me that, I don't even have to try to learn this from you, I can just learn it somewhere else. I did respond to your last post and here were my thoughts: "Using the same block" -- What block are you talking about? Initialization b...

Somebody throw me a bone here, seriously!!! What exactly has KFF achieved?? All I know in a rough sense is that he has sucessfully performed some effect on SPC, "emulated" by the use of rapidly altering loop points during a sample playback.. But from a general perspective, what did he prod...

FYI I updated my previous post like 20 times.. please take another look at it

Be prepared for a barrage of questions!!! So all the sample IDs refer to the same sample, but at different loop points?? Yee, but what effect have you exactly achieved here?? Is there a name for this, and does it require a certain type of sample waveforms to produce the effect? I have no idea what's...

KFF, what exactly is happening here?

I did it on the PCE with a 7khz timer, but it was kinda noise-y/gritty. The SPC has faster timers if it helps, one is 32,000 Hz.. the other 2 are 8000 Hz.. An .spc file is 65kB, so it must be the contents of the RAM plus some kind of header. Besides the header(s) and RAM are also the DSP registers,...

Can the DSP generate interrupt for when a channel sample block encounters a 'loop' point? Yes and no, -- although an interrupt cannot be generated, you can use timers and check the ENDX register. ENDX signifies each voice's arrival to the BRR end block. This will be the last BRR block before the lo...

The SPC700 has no interrupt sources wired to it. It has only the interval timers. Hence "timers as interrupts.." == find an appropriate timer (3, one of which is high resolution), and evaluate an appriopriate interval to "interrupt on" -- but if you're doing "heavy" pr...

Ramsis I love your demo dude! Nice work!

You can undo your work & see if the SNES works stock.. then you can maybe have a better idea that the system is still OK just by itself. Then you'll know where the problem is -- the system, or your hack.
