The title say everything
This old but great game plays the music at extremely low volume on Dreamcast.
I have re-encoded the original soundtrack, with higher bitrate and volume (ram permitting)
It needs a deep test, but seems better now

Re: OpenTyrian - re-encoded soundtrack [TEST]
I was just about to update this with SDL1.2.1.3DH = dreamhal fast blit speed and kos2.0 I guess i still post it ? 20% faster i can fixed the sound problems no more jerky scrolling clouds etc sh4 asm blit routine
How loud the sound is controlled by the code so no matter how much you put up or re encode the wav files it play at the same level..
Major problem with this is the mono music and the code is set to 1 channel now the mixer balances between sound effects and music so if you raise 1 the other gets lower in the code..
want see how this really ran on hardware compare to dc emulators
Above runs perfect on dc emulators i will have to test my update and see if i have fixed the problems
old port
Limitations:
- Game crashes on Instructions section.
- No network play.
---------------------------------------------------------
Things i have fixed crash on instructions screen
crash on level 2
trans
If it still plays like crap on dc hardware with sound on only fix is moving the sound to cdda music

I will show my update on hardware see how it plays..
When injet ported this and had the api's sdl_mixer had broken stereo and broken double buffer dma

Example of it running on debug no matter what you encode the files at they play at OUTPUT:> Initializing SDL audio...
OUTPUT:> Requested SDL frequency: 44100; SDL buffer size: 1024
OUTPUT:> Obtained SDL frequency: 44100; SDL buffer size: 1024
OUTPUT:> Requested SDL frequency: 44100; SDL buffer size: 1024
OUTPUT:> Obtained SDL frequency: 44100; SDL buffer size: 1024

Re: OpenTyrian - re-encoded soundtrack [TEST]
Thank you for let me know Ian, so it seems another one that performs very differently from emulators and real hw...
The original seems require to encode the audio with 22050 frequency max and 4MB max size (or goes in out of memory)
In reality this play the music louder than the original, but i see that the issue is the real hw and the original player in the code lol
I'll try your fixed release asap, because i want replay this good game also on DC

Re: OpenTyrian - re-encoded soundtrack [TEST]
Kinda interesting discussion here on the music, since the music in the PC version was FM synthesis. So we're doing it as PCM here on dreamcast because it has no capability for that.
Would there be less overhead if the music was CDDA?

I fixed this now runs correct on dc hardware long time ago..

the father thread is here

yeah, the switch to cdda have helped a lot the performance of some games, expecially when played on real hardware
Cave Story ie is another
some ScummDC games too offered (sadly only in past) this possibility too, like Zak mckracken FM Towns, Goooblins serie and Kyrandia (this last not perfect btw)
the scummvm team seems have abandoned that path, would have helped a lot on DC imo

Thanks for your work Ian, I missed it before. Looks fantastic. As good as the PC version ever was.
