Been updating via my own site ultimateamiga.com
Basically, I have put wip4 source to one side for now. May return to it later.
I have turned my attention to experimenting with current PSPUAE.
So far, I have completely re-written sound backend and moved paula to PSP's second CPU (Media Engine), which runs slower @166MHz, however thats good enough for audio. So its doing all the audio, buffering, vector mixing and output. So that takes away alot of pressure of main CPU.
I have been using state of art to test. Before any changes, CPU was at 400% load nearly all the time. After just sorting sound, its dropped to 200% work load. I believe sound improvements are complete, not much more I can to do it.
I'm currently in process of re-writing rest of backend. GFX is next.
Have some cool ideas, like converting GFX to textures and using VRAM direct. Also, looking at pixel perfect.
Should also mention, sound no longer crackles and pops any more. We now have crystal clear 44.1 KHz perfectly seperated like the real amiga.
