Re: Questions on sound for Dreamcast

I'll answer what I can:

2. Either 16-bit raw PCM, or 4-bit raw ADPCM (the Yamaha variant).

3. CDDA has a direct path from the GD-ROM block to the sound hardware. For everything else, including WAV files on the disc, you need to copy them to RAM and steam them to the sound firmware.

Re: GLdc 1.1 Released

My bad, I thought -Ofast was for faster compilation times (so less optimizations).

Why do you compile it with -Ofast?

Re: GLdc - Call for testers!

Probably highest amongst the many things that could potentially be considered blockers is pollution of the global namespace with functions that aren't prefixed in any way... By that, I mean internal functions that you can't make static for whatever reason. I recall there being quite a few of them b...

Re: About 50/60 Hz

All PAL monitors still accept 50 Hz. But I'm pretty sure that they all accept 60 Hz as well now.

The Hitachi manual is copyrighted by Hitachi, but was released to the public BY HITACHI for free so that programmers could use their processors more easily. Yes.

Re: Re : mat_transform / pvr_prim vs mat_transform_sq

One of the... uh, interesting things the library does is that it doesn't use SQs or DMA to submit data to the PVR. Since the library writes the intermediate data to a buffer between passes, you would either have to stop and copy the final results to the SQ manually, wasting CPU time, or dump everyt...

%f is for floats IIRC, for doubles you should use %lf.

Re: Compiling newlib

GCC 4.9.1 might be worth a try. It gives a great boost of performance on MIPS, it should be the same for the SH4 (as both aren't really "lively" archs, it's probably due to high-level optimizations).

30,000. That's 1/5th in less than 12 hours. It's always like this at the beginning, so it's not very surprising. Orly? 33.5k in 24 hours is impressive by any measure. We did exceptionally well within the first 24 hours. I talk with experience, our project got funded via kickstarter: https://www.kic...

Re: How can I diagnose if the problem is the CD or the laser

The Dreamcast having issues to load GD-roms is not something new. It happens a lot if your laser isn't perfectly calibrated.
