This one is mainly focused on fixing some remaining inacurracies with Video & Sound emulation. I also added support for software filters by Blargg which simulates the artefacts of the NTSC video signal, making the emulation experience more accurate than ever !
Those filters being relatively slow, even for the Wii, I also took some time (well, quite a lot in fact) rewriting many part of the emulator (CPU interrupts and memory handlers mainly) which actually results in a quite noticeable emulation speed boost...
Last but not least, this update is compiled with the last released libogc & libfat, which bring some new features (SDHC support, USB storage support...) that some of you might find interesting.
That's all, next update should be aimed at the new menu interface mainly, then we could probably move on to some more interesting stuff
WARNING: due to some major internal changes, Savestate files from previous versions are not compatible anymore (SRAM files are unchanged). Also, you might want to delete your old configuration and history files from your SD CARD, as filenames have been modified.
