  • High accuracy and compatibility for A500, A500+,  A600, A1000, A2000, CDTV

  • Good compatibility (Cycle-exact chipset emulation, CPU memory accesses are cycle-exact, CPU internal instruction execution speed is not exact) for A1200 and CD32

  • Fast CPU emulation only (chipset/chip ram CPU accesses optionally cycle-exact) for A3000, A3000T, A4000 and A4000T. To see all features, follow this link

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.
