ME WANTS HORTEKA *nt* by hcs at 2:24 PM EDT on June 14, 2005
since I don't even know what processor the DC runs on...

Well, I admit, I was thinking it would be nice if you could be the one to do it. However, I was 90% certain that you wouldn't be able to pull it off (after all, you did already create your own format based on the N64. And now you're creating your own hombrewn libraries for developers. Not to mention lack of free time). Besides, the DC is, to a degree, the rival of the N64. I certainly wouldn't expect you to have researched it to much, since most of your work is based on its "rival" (yes, I use the term rather loosley).

Anyway, what you've done so far is great! Thank you HCS! (And, with my new 2mgz CPU, USFs don't kill my CPU anymore!). Keep up the great work. Mouser X over and out.

P.S. Maybe you know someone who has access to the source code for a DC emulator? If yes, maybe you could convince them to create a hack that plays DSF files? (Yes, I'm aiming for a huge longshot here, and I'm at [i]least[i] half joking (probably more)).

2mgz?! No joke they don't kill it anymore. USFs look at it and laugh in its face, sending the poor CPU running, crying for its mommy! Geez! That couldn't even run windows, in any form! I ment 2ghz... If you couldn't guess...

*Mouser X feels slighly foolish.

Mouser X over and out.

P.S. Dognabbit, I didn't even do the italics correctly... I suppose it goes to show I've never used such features in a forum before (well, not without the buttons present).

Last time I checked, the DC runs on an Advanced Risc Machine (ARM) 7, and the Saturn runs on a Motorola 68000.

Found this info on the DC CPU

CPU: Hitachi SH-4, 200MHz clock rate, 360 MIPS (millions of instructions per second), 1.4 GigaFLOPS (floating-point operations per second), 128-bit 3D calculations, 64-bit data bus, 800+ MBytes/second bus bandwidth

The trick, then, is to figure out the sound hardware.
Get to it.

please forgive the sarcasm of the previous post

Audio: 45 MHz Yamaha Super Intelligent sound processor

* Channels: 64
* Sample rate: 44.1 KHz
* Special effects: reverb, delay and surround sound
* Memory: 2 MB RAM

is that enough info?

How is it accessed by the CPU? Does it run an independent sound program a la the SPC (I think the Saturn also has an independent processor for sound)?
by hcs at 7:22 PM EDT on June 14, 2005
Considering it has a speed associated with it I'd say its and independent processor, good. Neill probably assumed that and DSF is probably just a dump of its memory, though that might result in incompatibility with some odd games.
In that casue all you need is source for an emulator for this processor (MAME might have one, I don't know) or if one doesn't exist get some technical documents and get to work. Check through psf_rippers for Neill's comments on it, they might lead you in the right direction.
