Well, looks like both JIT and DYNARec are dead ends in their current form.
Looks like if I want anything concrete and fast, I will have to build my own from ground up. Adapting code causes to much over head and ultimately kills the speed.

I have been working on (for last week) FAME/C cores however and that has given the most speed increase.
So will continue working in that area. I have also added the CPU to CHIPSET equivalent to it and that helps.

I think I'm up to beta 50...

Finally after a week of micro adding native code.
I switched to bulk adding in batches and am now seeing some speed increase. Will continue to add more native code.
Once that's all done, I will then optimise code for speed.

DYNARec seems to be working 100% as it should. So fingers crossed, I can surpass the standard CPU now (unlike JIT, needs a complete rewrite).

Have DYNAREC working, now doing the long winded part.
Getting speed out of it. Going very slowly, .

Not much to update yet, apart from working on a port of Notaz's DYNAREC from Daedalus64.
Spent last 4 days making its frontend not cost anything in speed before implementing native instructions.
Slow going, but if I get this right, we could have the speed increase we have been missing.

Personally, I would be happy with 50 FPS with 100% cpu usage and skip every third frame.
If we can achieve that on 333MHz, then once overclocked to 400+MHz, you could proberly achieve skip every one frame at 50 FPS.

Fingers
