Been slowly adding more advanced sound, over last few days.
Gained 3 - 4 FPS, before Paula on ME work started. So just in the process of re-implementing Paula fully on ME CPU.

Almost finished native sound. Speed is pretty good, 38 - 41 fps (with frameskip 0).
Trying to keep speed the same as it is, has been challenging. After about 10 tries, its almost there.

Using what I learnt with wip4. Using SC ---- ME mailbox straight into ME local 2/4 MB Scratchpad memory and then let run ME run async on delivering audio, stops the bus from being hammered by SC and ME. So no overhead.

Right after a lot of thought and pulling out hair.

E-UAE wip4 is dead end on PSP. Fact is the old 2014 was last release with the fastest speed possible with E-UAE wip3. So forget every version after that (based on old 2014 source), they are early experiments (using ME old way). I will rework old 2014 source with newer features, updated gfx and sound, also fix remaining bugs. I will do that at a later date. Its not all bad, learnt so much over the last 10 months.

I have archived DYNARec and JIT work, as although they work, they have added so much overhead, they are slower.Read More

Currently on beta2 of new port. Using basic backends, I have finished all backend bottlenecks.

Moving on to full source allegrex optimisations. Going slower this time. Benchmarking all updates, to ensure we lose no speed only gain speed.
