First major thing is "Advanced Launch" page where you can customize the emulation before it is even started. It is really needed for BIOS selection, PAL/NTSC and many others like memory size, recompiler/interpreter selection. When these settings varies between saved states it makes these states incompatible though. Many things in the core library was changed in order to make it. For now only NES emulation will benefit from it (explained why later). But of course every emulation will get their own settings in the future.

Many customizations for touch screen:
- buttons are back - harmattan styled (as an option)
- grid (like in the image at wiki, as an option)
- haptic feedback
- fancy look of settings - provides the same view of buttons and grid as in the emulation, so you can easly customize it to your needs
- configurable d-pad and right buttons area size
- configurable diagonal area size
- l2/r2 in psx

I have started with NES when it comes to improving quality and performance of emulation. I know you would see others to be improved but I needed easy one to start with "Advanced Launch" functionality:
- APU replaced (partially done)
- recompiler (partially done)
- PAL timings correction
- 6502 cpu interrupts timing fixed
- mapper 5 glitches fixed
- pal/ntsc switch
- more settings (partially done)
With the recompiler and new apu added it will be blazing fast and sound glitches will be no more in the NES emulation.

TODO:
- finish NES APU rewrite
- finish NES CPU recompiler
- finish some minor things and add couple of settings to nes emulation
- add states browser where you can see how much space they takes, you will be able to run the game directly from the state, ability to backup and restore all states, and most importantly state converter will be added, so you will not worry about current states. I think you would really like this feature
- script for faster sixaxis configuration
- and few others ...

Many small things improved, like: emulation and settings in one view -> no more floating windows, improved quality of rendered icons that goes to home screen, bug in gba config parsing - fixed -will make some games more playable or make them able to run at all, many optimizations, .....

And I must tell you that I am targeting PR1.2 now.
