WinUAE 2.7.1 beta 2

– BPLCON1 mid scan line modifications now should match real hardware 100%.

This was very big change, old emulation was functionally close enough but very far from real hardware behavior. Old code couldn’t emulate some side-effects correctly.

– Partial/full scanline based mode (“SPEEDUP”) is again used more regularly, “is it safe to use” check got partially broken during 2.7.0 betas. It is also more optimal in AGA 32/64-bit fetch modes.
– AGA border sprite in right border and 2x or 4x horizontal sprite pixels (vs bitplane pixels): sprite’s rightmost pixel(s) were missing.
– Superhires and top or bottom border sprite: graphics garbage was seen in border area, memory corruption was also possible in some situations.
– Magic mouse + mousehack mode now always stops keyboard input when mouse is outside of emulation window, even if window still has focus.
– 68020/030 CAAR register preserves also all reserved bits.
– Disable JIT if config has 68000/010 CPU and non-zero JIT cache size.
– 68020 CE broke interrupt state fetch, interrupt didn’t clear if write to INTREQ was immediately followed by RTE. (b1)
– Does not anymore require SSE2 capable CPU (b1 did)


Enjoy Life, be kind to others.
