QSound! (CPS1.5 beta 2) (Patreon)

It's taken about 6 weeks of development but the DSP16A chip is now part of our FPGA family. This is the heart of QSound. Yes, we now have QSound, the sound system of CPS2, ready.

So here it is the second beta release of CPS 1.5, introducing QSound. There is still work to do but the experience is way better with the awesome sound effects of these games. Some notes:

1. You need the file qsound.zip to get the sound to play. Place it with the rest of your MAME roms if you use MiSTer.

2. QSound output is triggering artefacts in the digital-to-analogue converters of both MiST and MiSTer. The artefacts are much worse in MiST and can be heard when music stops. In MiSTer it seems to be a noise here and there. This may not occur in the HDMI sound output of MiSTer. I have not tried it yet.

3. NVRAM contents don't get saved so DIP settings do not persist after power down or swapping games. DIP settings are changed via OSD menu by selecting "test" after the game has started.

4. FPGA timings are not clean yet so for a small number of people, games may crash or show strange behaviour.

5. The pause screen is just a place holder for now. It will be ready for next update.

6. All CPS 1.5 original games should work correctly with music.

Thank you so much for your patience during this time. QSound is a big deal in terms of development effort and I was afraid of making you wait for too long.

Thanks again,Jose (jotego)
