Wow that means it runs super smooth and in a frame! Any news on progress with this emu and workign sound?[/quote]

actually i guess i wasnt clear on that. sound isnt working not because there isnt enough speed for it (that is what frameskip is for) but because it is literally broken. The sound processor is running, but not at fullspeed. This is how ian got it to slowdown after taking out my frame limiting code =\.

Since ian quit i dont know if there are gonna be any more updates on the emulator. The only thing i can think of would be to redo the z80 emulation with another z80 emulator that is prooven to work on the dc. either that or take out some compiler flags that ian used with it that i have heard to be problematic in stuff.

ian quit the scene ?????????????

Else about sound, I currently started to implement it in the actual WIP version (of the ps2 port of course), and I finally completely removed the streams functions (stream.c & stream.h) and directly update both cpu sound and mix them for each frame, result is that it's starting to work more or less. fm sound is working more or less, and sfx are working but not on all games.
Ym2610 sound core is also almost 10 years old, so I think to update it with a more recent one.
Anyway, I'm also thinking to replace the z80 core, as this is strange that some games have sound working, and others no...

so is the DC version dead? Â*???

Well, im pretty sure I am the DC coder with the second most experience with it. If evilo is willing to help me implement some of the things he did in the PS2 version, maybe I can try to make an update?

It's at times like this I wish someone had a picture of a PS2 hugging a DC saying it will be ok.

considering we have all seen the picture of the PS2 beating the DC to within an inch of its life, that would be a nice change.

great stuff, It would be really sad not to get sound working on the NEO CD emu. as its soooo close (ish).

I will help you with pleasure on fixing the sound code. I already provided fixes to ian on the z80 core, and he also provided me with fixes on gfx issues. ps2 or dc or even gc or whatever platform it is, we are anyway all in the same community !
Neocd/ps2 is also an open source project, so once next release will be out (once, additionaly to others additions, I will reach a good state for the sound support) you are free to pick it up from my site (neocd.ps2-scene.org) and report my modification to the dc source code, or if you want contact me to my email address ([email protected]) and I will send you current ps2 sound implementation. About helping you more deeply, yes but be aware that the ps2 is NOT using the SDL library, and that I don't have the DC SDK installed, so apart for the code itself, I won't be able to go further with any assistance.

see you soon.

And best wishes to ian :)

I've never see a coder of another system show such great respect and friendly ness toward other systems coders. It's great to see these kind of things in the comuinity.

wow, you seem to know alot about fixing the sound. Do you think you can fix the sound in this genesis emulator for dreamcast? It works but it keeps looping..

It requires a version of KOS with SPU DMA. He's using 1.3.x incr 133.
