[AMIGA] Winuae 2.7.1 beta 2

WinUAE 2.7.1 beta 2 [14/01/14]

• 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)

WinUAE 2.8.0  [05/05/2014]

Standard A500 compatibility is now practically as good as it can get without knowledge of blitter's undocumented internal logic design. (Mainly problem with some demos that accidentally modify blitter registers while blitter is already active)

New features:

• Full A4000T and A4091 NCR53C710 SCSI emulation.
• A590/A2091 and A4091 boot ROM GUI selection.
• Separate graphics filter settings for native and RTG modes.
• 256k ROM image inserted in floppy drive emulates A1000 KICK disk.
• Super Card Pro image file support (.scp).
• SLIRP network inbound port support (default: 21, 22, 23 and 80, others can be added by editing configuration file)
• Input panel previously toggle-only events can be optionally set to on and off state, audio/video recording input event added.
• Joystick/joypad can be used to control light pen cursor.

Updates:

• Remaining 68000 cycle-exact mode timing fixes.
• 68000 reading from write-only or non-existing custom register compatibility improved.
• Big chipset edge case compatibility update, for example demos with vertical "copper" bars work perfectly, real hardware glitches in horizontal scaling are now accurately emulated and much more.
• 68040/68060 without emulating unimplemented FPU instructions is now fully compatible with Motorola FPU emulation library, FSAVE special FPU exception stack frames implemented.
• Programmed modes (Super72 etc) now automatically select best fit horizontal resolution and is more compatible with different filter modes, also display positioning is improved.
• Recently dumped Arcadia arcade system ROM images supported.
• Debugger full FPU and 68020+ bitfield, and other previously missing 68020+ only instructions supported in disassembler.
• Magic mouse + mousehack mode now always stops keyboard input when mouse is outside of emulation window, even if window still has focus.

2.7.0 bug fixes:

• Unformatted partition hardfiles didn't mount and had incorrect geometry.
• Resolution autoswitch was not compatible with new interlace scanline modes.
• 68020 CE mode FPU exceptions fixed, broke for example KS 1.3 FPU detection.
• Sound glitches in games that use OCS compatible "fake 60Hz" screenmodes.

Bug fixes:

• Keyboard led indicator state syncronization problems fixed.
• Fixed very rare JIT FPU bug introduced in 1.2.
• Vertical centering works again, improved horizontal centering.
• Full tablet emulation boot guru fixed.
• Graphics glitches in some borderblank and border sprite modes.
• Master floppy write protection setting was not loaded from config file.
• Some narrow AGA modes clipped some pixels from right edge of display.
• A590/A2091 didn't work in all supported CPU modes.
• CPU polled disk reading was unreliable in some situations.
