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.

OK, Still here, still trying, .

Have decided to start from scratch. Currently have a vanilla port, with nothing changed and with basic backends.
Lastnight, I finished my multicpu idea. Now running lots of testing to see if it has actually improved speed.

Currently, have almost the entire emu running on ME CPU, with SC, taking care of the host PSP stuff.
Will re-add all work from...
