Beta 12:

- Windowed mode status bar button mouse click off-by-one fix.
- If command line has more than one -f/-config= parameters, config will be now reset to built-in defaults only once, before first config file is loaded.
- Updated CHD support, uncompressed CHD write support added, can be mounted as read-write hardfile. (CD subchannel support may or may not work, there does not appear to be easy way to convert ccd/sub/img combination to chd)
- CSPPC/BPPC IPL_EMU register´s M68K_IPL bits only change when PPC is interrupt master.
- b11 Blizzard accelerator Z3 autoconfig hack didn´t work correctly.
- BlizzardPPC flash mapping fixed (b11)
- 68000 mode, without CE and more compatible, RTE instruction didn´t check for odd program counter.

accelerator_roms.zip updated again, now BPPC images are full 512k, rom scanner won´t detect smaller images anymore. Manual selection still works with 256k images.
