E-UAE WIP4 running on Sony PSP

Finally got it to boot and display sort of a kickstart screen. Hard part is finally over, boots with no errors, .

I know what I'm doing tomorrow. Fixing it so it displays properly, then will start on adding mouse / joystick support, then menus.

Now have sound and gfx working correctly. Just profiling code, so I can increase speed as is currently quite slow.

OK, so I have been spinning gears on this for last few days.
Getting fed up of not being able to shift the CPU usage, even with framskip.

After hours of tweaks for PSP hardware. I finally realised, after adding auto frameskip.
I looked at E-UAE homepage and found out, there was no auto frameskip, hence me adding it.
However, it turned out frameskip is just broke. For last week I have been optimising and tweaking, using different FS settings, without realising, every test was with FS stuck on 1.

Currently up to 45 FPS running bubble bobble, it feels quite smooth. I have added buffer to sound to improve it for testing.
Currently, CPU load is around 120% at around 45 FPS. Which is pretty good considering, When I started it was 200%+ at 17 FPS.

Will get Frameskip fixed, as its important.

So rewrote GFX backend. Had it working fairly decent. Pixel perfect 4:3, 16:9 stretch. Then I stupidly messed up source and forgot to backup.

So spent last 4 days, re-writing it all again. Have to be fair, glad I did. We now have;
1, 4:3 pixel perfect & 16:9 stretch.
2, Autozoom (both 4:3 and 16:9), incase you wonder what it is. It only draws to the screen the actual amiga content. Meaning no bands around screen.
3, Mask effects. Currently, there are 3 (1=scanlines, 2=rgb apeture and 3=Shadow mask).

I will leave it there. As I'm getting way side tracked. GFX-PSP Backend is complete.

As a side project, since February I have been working on mips JIT.
I'm almost at a point to start passing instructions, so I'm hopeful, soon we will have JIT support.

I could really do with some beta testers.
As I can only test so much.
