Hi TrekkiesUnite118,

Neither

It's software rendered mode7 (software because there is no hardware instruction to do that on the Sega Saturn unlike the Super Nintendo).

You can move in any direction. but I disable rotation recently because it's useless.

Indeed, it's better and faster to use 3D rendering in this case.

Hi,

I added PCM audio file support.
You can now play PCM file from CD.

To convert any audio file to PCM under Linux or Windows => http://ffmpeg.org...

Just some restriction due to the Sega Saturn hardware:
  • Compatible Samplerate : 8000 to 44100 Hz (-ar option)
  • Compatible PCM format : s8 (-f option)
  • Compatible mode: 8/16 bit mono/stereo
Some command line:
  • ffmpeg -i A.WAV -f s8 -ar 44100 A.PCM
  • ffmpeg -i A.MP3 -f s8 -ac 1 -ar 8000 A.PCM
Now in Jo Engine:

jo_sound my_snd;
jo_audio_load_pcm("A.PCM", JoSoundMono16Bit, &my_snd);
...
jo_audio_play_sound(&my_snd, 0);

Bye

great job ! just a question, how do you handle multi channels and random number of pcms to play ?

 johannes Jan 10, 2016
The channel number is the second param of jo_audio_play_sound();

yes i saw that but each time i used multiple PCMs i had some problems with playback and some sfx were lost.
for instance on xrick i had to loop on channels to find which one is available, with hardcoded channel number it never worked or maybe just on emulators.
Code: 
  
  if(slSndPCMNum(_Mono)>-1)
   for(i=1;ibuf,sound->len);
       //if(sound->buf!=0x00232000)
         //slSndFlush() ;
         break;
     }     
   }
just for that, i have pushed xrick on github : https://github.com/vbt1/xrick...

Interesting, I'll check this more closely

Thx vbt

 johannes Jan 10, 2016
You're right vbt ! I'll make a fix

 johannes Jan 10, 2016
New version updated with VBT audio fix.

I also added the possibility to change printf color and use multiple color at the same time
