Most Recent Changes
OSD led status bar positioning fixed (b16)
OSD led status bar is now DPI aware. (NOTE: moving window from monitor to another monitor with different DPI does not yet work correctly)
BPLCON0 UHRES-bit also disables DDFSTRT/STOP limits according to Alice schematics
Sprites in right border were still not fully correct when they crossed "hidden" hpos=0 position. Sprite didn't disappear if start position was after hpos=0 wraparound and sprite wrap around if it started just before hpos=0 stopped too early, last few pixels were missing before start of hblank. (Thanks ross for test program)
One more blitter fix, last D write was done even if blit didn't have D channel enabled.
CPU Idle slider value added to GUI. (It was not very clear which end of slider disabled it)
Loading CD32 statefile with CD audio playback active: mute state was not always correctly restored.
Loading CD32 statefile with CD audio playback active but paused: pause state was ignored.
Loading CDTV statefile with CD audio playback active but paused: very short bit of audio was played before audio paused.
Added "Restart emulation" input target. Does same as GUI "Restart" button.
Reverted few b1 bitplane emulation changes. Complete rewrite will be planned for later because current emulation behavior is not really correct when compared against Alice schematics.
