Request: Picodrive "Ogg Vorbis add-on"
« on: October 02, 2014, 02:03:52 pm »
The Picodrive has got a very good emulation of SEGA CD/MEGA CD hardware... it would be great to have the support for the Ogg Vorbis playback (I think that the GCW Zero has got the enough processing power to decode the .ogg files without show slowdowns in the frame rate... moreover, in this way, the CD games would occupy a relatively small space in memory)...

hereunder the link to the "original topic" :

Hereunder some examples to get an idea of the "storage saving" ...

Adventures of Batman & Robin:
- Iso+waves (L-PCM, 16 bit, 44.1 KHz, 16 bit, 1411 kbps) = 298 Mbytes
- Iso+oggs (Ogg Vorbis, 16 bit, 44.1 KHz, 16 bit, 128 kbps) = 147 Mbytes

Hook:
- Iso+waves (L-PCM, 16 bit, 44.1 KHz, 16 bit, 1411 kbps) = 369 Mbytes
- Iso+oggs (Ogg Vorbis, 16 bit, 44.1 KHz, 16 bit, 128 kbps) = 45 Mbytes

Mickey Mania:
- Iso+waves (L-PCM, 16 bit, 44.1 KHz, 16 bit, 1411 kbps) = 477 Mbytes
- Iso+oggs (Ogg Vorbis, 16 bit, 44.1 KHz, 16 bit, 128 kbps) = 51 Mbytes

Strange it doesn't support OGG.. Maybe a peculiarity in the way it used a previous streaming mp3 library?

I remember in the GP2X days Picodrive supported MP3-encoded SegaCD audio just fine, with no slowdown at all, so I'm sure it won't be an issue using OGG on the GCW!  (OGG is very light on resources too)   It probably would have supported MP3 out-of-the-box on GCW, but we cannot include a MP3 library because of patent/licensing crap in the USA, unfortunately.

As I recall Picodrive does accept MP3, I had that working on Sol-Feace

If I remember well, the Picodrive had got the support of the mp3 playback until the v 1.56 ... from the v 1.80 it was removed, probably for licensing and patent issues ...

Without mp3 support, Snatcher has constantly freezzes  :(.

Maybe with Ogg support, this problem would be solved.

In 1.56 the game runs fine (with mp3), but this version has other problems (graphics & sound bugs).

It's a pity, in Picodrive for GP2X Wiz this game runs perfectly (I finished the game in my Wiz some years ago)

Last time, I started playing in GCW0 and I finished it in a GPD 5A. Playing in GCW0 was a nightmare

in few words... a Picodrive version with the Ogg Vorbis support would be very welcome! ;)

Ker, I'm testing Snatcher with GenPlus GX and seems works fine, no audio problems, no graphics bugs and the spanish translation works fine... :o :-*
