Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Interlace timing was broken, fast drawing mode calculations affected non-fast modes. (b26)
- Remove interlace artifacts works again (b26)
- "Default" filter mode now adjusts to Display panel overscan selection.
- Fast mode superhires + Display panel resolution set to hires had horizontal scrolling glitches.
- Add Harddrive listed some CF cards (maybe others too) as unaccessible MBR partitioned with single partition even if they had RDB (or nothing). Broken in some earlier beta.
- 65HC05 and 8039 keyboard MCUs was not fully reset when reconnecting keyboard on the fly.
- This does not change "right edge glitch" emulation. I am still not decided what to do with it. "Fast mode" does not have enough information to handle this properly but I also don't want to disable fast mode completely when this side-effect is possible. (It can be possible and even happening in other situations but most of them can't be seen)

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Automatic resize filter added size multiplier twice in some situations.
- Collision CLXDAT register reads are now also horizontally cycle based (but not yet pixel perfect). CLXDAT reads are still line based if configuration does not have at least memory cycle-exact or CPU is in fastest possible mode. No real world program cares and also collisions are used really rarely.
- Programmed mode that enabled programmed HBLANK and programmed HSYNC (BEAMCON0 VARHSYEN and/or VARCSYEN) without VARBEAMEN used default PAL/NTSC positioning instead of using programmed HBLANK values for more accurate positioning.
- 68HC05 keyboard controller emulation keyboard matrix last row was not working.
- Fixed fast drawing mode last line having wrong color, mostly in programmed modes. (Last line color changing to black when mouse is near the bottom of screen and back to border color when moving mouse upwards).
- FPU FMOVEM to/from extended uses "original" code when JIT is enabled. This is test fix for reported "random" FPU value changes in JIT FPU mode.
- Last line border/blank bug was last known fast mode glitch. Report if there is still glitches remaining.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Fixed possible drawing buffer overflow when drawing blanked lines.
- HAM state was reset when HDIW start matched even if HDIW was already open.
- Switching BPLCON3 BRDSPRT off mid-screen didn't immediately recalculate sprite visibility.
- Fast mode stopped drawing bitplane early if display needed horizontal scrolling ("misaligned" DDFSTRT and/or BPLCON1). Should fix remaining fast mode missing graphics problems near right border. (Usually only visible if HDIW ended after bitplane)
- Display panel "Resolution autoswitch" works again. (Was gone in v6 rewrite)
- Cirrus Logic SVGA chip emulation now only supports planar VGA when using text mode, 4 color or 16 color graphics modes. Can increase performance in normal SVGA modes.
- Double (not fields or fields+) interlace mode in automatic scaling/resize/etc mode never recalculated size/position when switching to interlace mode. (It kept waiting for both odd and even field but now only full frames are drawn in doubled interlace mode)
- Please report (again) if fast mode graphics glitches still appear. (and goes away if optimizations=none)

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- If bitplane DMA was active behind vertical blanking, it was incorrectly used for automatic scaling horizontal start/end detection.
- More horizontal start/end adjustments to exactly match 5.3.1 manual filter behavior.
- TV overscan modes are now almost same as in older versions. Narrow is slightly wider.
- Increased event queue buffer size, multiple audio channels with AUDxLEN=1 could overflow it.
- When filter mode like autoscale detects mode change, force full redraw (without this fast mode lines are not guaranteed to be redrawn with correct position or blanking)
- Borderblank 1 shres pixel early end emulation was incorrectly emulated also in border area. In some situations, when HDIW position and/or borderblank state was modified during border, it could have caused single wrong colored pixel glitches.
- Fixed bitplane garbage in right side of display in some fast drawing mode conditions (Usually hires or shres and HDIW end was larger than bitplane end)
- (Pointless) VHPOSW (like AR3 does) writes without CE caused graphics glitches in fast modes.
- Line count OSD (313p etc) now shows "----" (like FPS counter) when display sync is not stable. Not very useful to show mostly random values in weird situations.
- Fixed A1000 direct (without using boot ROM + KS disk) KS ROM loading.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Automatic center filter mode fixed.
- ECS superhires filtered lores implemented. Filtered lores odd/even genlock data is also now "filtered".
- In some situations right border had 1 lores pixel difference between border and hblank depending on drawing mode.
- Fixed AVI recording crash.
- Fast drawing mode + NTSC: left and right border glitches should be finally fixed.
- Fixed fast draw mode last line changing between blank/border when mouse was near the border.
- When reset was executed, new screen width included old short/long state. In NTSC mode new screen width was randomly 2 lores pixels wider.
- When in fast non-CE mode, switching from RTG to chipset and if fast RGA buffer become full, it was possible for CPU chipset writes to arrive in Denise side in different order, causing strange side-effects. (Frontier black screen)
- Partial fix for A2024 emulation. (All display port monitors need some updates)
- Fixed slirp use after free bug (Andreas Grabher)
- Added (config file only currently, "rtg_noautomodes=true") option that disables uaegfx automatically generated screen modes. With Picasso96 v3.4+ and P96Prefs new modes can be created manually, just like when using real hardware. Note: Old Picasso96 and/or PicassoMode utility don't support manual uaegfx modes.
- Added 3840x1080 to known uaegfx resolutions list ("known" = gets static mode id if autogenerated)

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Fast mode drawing + HAM + left TV overscan blanking part of display caused HAM artifacts.
- Fast mode shres HAM in hires or hires HAM in lores didn't include skipped pixels in HAM color calculation.
- Fast mode drawing didn't mask bitplane addresses with chip ram address mask.
- Fast mode Remove interlace artifacts scrolling glitches mostly fixed.
- Garbage was possible in right border if bitplane ended earlier than HDIW. Fast mode only.
- Filter settings should not limit display width or height in extreme or higher overscan modes, extreme (and higher) should always show whole display area.
- Hardware emulated RTG boards didn't have vsync timing (b21)
- DIWHIGH state restore was unreliable.
- Automatic scaling (and related filters) now also work correctly if HDIW end never matches.
- Filtered lores option supported again. (If Amiga mode resolution is higher than display panel mode: normally every other pixel is dropped, filtered lores mode takes average color of two pixels)
- VPOS(H)W write refresh rate changes work again. (For example Wings of Death, DynaBlaster fake 60Hz). Non-CE modes only accept forwards vpos move and not out of range values.
- RTG with default settings (all 4 checkboxes in left side of RTG panel unticked) display positiong fixed.
- Adjusted display position and screenshot position/size slightly to better match older versions.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Filter panel TV modes and filter overscan blanking work correctly again (not doing anything since b1). Extra horizontal and vertical blanking handling changed again, might cause side-effects.
- NTSC horizontal long/short line artifacts are gone in TV overscan modes. NOTE: NTSC still have problems with some filter modes.
- Ultra extreme debug marker colors changed.
- Automatic scaling used also non-bitplanes to detect horizontal start/end. Now it matches 5.3.1.
- Automatic scaling + fast drawing mode: detected topmost line was 1 line too large.
- Screenshot when in non-PAL/NTSC mode memory out of bounds access fixed, caused random crashes also when entering GUI.
- Fixed possible crash in fast mode drawing code if number of planes changes suddenly.
- uaegfx vertical blank interrupt might have been duplicated or lost in some situations (very old bug), depending on RTG panel refresh rate setting.
- Ignore V(H)POSW writes when in non-ce modes. KS V(H)POSW writes when screen mode changes caused strange side-effects, including unreliable RTG/native mode switches.
- Passthrough printing fix for v4+ Windows printer drivers (untested)
- This hopefully fixes SysSpeed native/RTG switching.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Long/short field mode change (single LOF change, not interlace continuous toggle) didn't recalculate internal screen mode configuration. As a side-effect it also caused random last line to not being updated correctly when switching from long to short.
- Fixed fast mode drawing and TV overscan mode top/bottom lines not being always updated correctly.
- Audio hack that prevents high CPU usage if program sets (uselessly) AUDxPER to very low value is now more aggressive but not aggressive enough to break Spaceport. (R-Type II, ReadySoft 64 emulator)
- Serial port transmit works again in non-ce modes.
- Integer scale horizontal/vertical resolution aspect ratio correction should now work more sanely (for example if superhires + vertical doubling, result is always vertically doubled first, after that integer scaling ratio is selected). Supports also programmed doublescan modes.
- In AGA mode reads from write-only registers are now closer to 5.3.1 and older version behavior. (Artificial Paradise / NGC)
- If resolution/plane count was set before FMODE was updated and original FMODE was too small for new mode, drawing mode was reset to normal (HAM and EHB was drawn as normal mode). Affected hires and shres AGA HAM and EHB modes.
- Non-accurate CPU mode and writing to CIA high timer register didn't load timer from latch immediately in oneshort mode when timer was already running. (Introduced in some 4.9.x version)

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Display panel lores combined with superhires native mode is not anymore supported (It wasn't really working that well in previous versions either). Nothing is drawn in this combination.
- Filter panel adjustments also affect GDI mode in real time. It still has ugly flicker. Use only if D3D9/D3D11 is not available.
- Output D3D9/D3D11 texture was still locked when it was rendered. Old D3D9 drivers didn't like it (and was wrong in any case)
- Integer scaling superhires aspect ratio correction didn't work.
- If selected graphics API is not supported, test all other options. Previously failing D3D9 switched to GDI, even if D3D11 was available.
- Interlace + TV overscan modes: extra black line was visible near the end of display. (fast optimized modes are not yet fixed)
- Fixed attached sprites (only odd sprites affect attachment state)

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- PCI bridge autoconfig was unreliable, at least with Mediators, first boot worked, following reboot might not have. (broke few betas ago)
- D3D11 mode OSD was not drawn and usually had single frame in wrong position during mode changes.
- Wait for blitter option could cause recursive calls (and in worst case crash due to stack overflow) if delayed chipset pipeline callback was active.
- Some updates to fast mode drawing. (was accidentally disabled in b17, genlock support fixed, odd to even bitplane collisions (CLXDAT bit 0) supported and some other adjustments)
- Second refresh cycle was not processed in RGA pipeline because inactive NTSC STRLONG check incorrectly skipped part of pipeline processing. Whatever copper wrote in previous cycle was not written to Denise custom register causing strange side-effects.
- OCS/ECS sprite behind hires bitplane drew bitplane in lores. (Also drew in lores when sprite was on top of bitplane but it was not visible because sprite lores pixel hide both bitplane hires pixels)
- ECS Superhires fast mode drawing supported. (Except if display panel is set to lores but that is useless combination anyway)
- Virtual mouse driver horizontal movement works again.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- Interlace artifact remove option didn't fully work in non-ce modes. (fast mode lines were not "scandoubled")
- Interlace filter was ignored (had disappeared during chipset rewrite)
- Filter modes default and no scaling fixed (b16)
- New output buffer lock state validation causing blank RTG screen in some situations (Validation is more strict now to detect bugs. It was a bug.)
- Remove color depth GUI option and internal color depth checks. 32-bit host depth is the only supported color depth. (Was already partially removed in b1)
- Serial port transmit buffer empty bit didn't get set when serial port was in "non-accurate" mode. (68030+, JIT etc where cycle accurate timing is not important). Serial port update is not yet complete.
- Visual DMA debugger and other on screen debugging features work again. Also now works with active genlock (for example when ALG game is running)
- KILLEHB BPLCON2 bit really works correctly now.

Eine neue Beta-Version des Amiga Emulators WinUAE wurde veröffentlicht. Download hier: WinUAE 6.0.0 beta series
Note:
- EHB was broken in ECS Denise and AGA modes. KILLEHB was always detected as active.
- Add harddrive last partition selection didn't work correctly. Also non-0x30/0x76 partitions are now allowed to be selected.
- When screen mode switches (PAL/NTSC/VPOSW trick etc), delay host side switch until at least 2 back to back frames have same width and height to prevent single weird size frame changes (for example during boot when VPOSW LOF bit is changed in random position from zero to one causing height of frame to change temporarily)
- Disabled too annoying CD audio OSD led flicker.
- Possible fix for autoscale not always detecting top and bottom borders.
- Filter internal scaling and positioning cleanup. Simplified coordinate and size calculations etc. Should not have any visible effect but it might break some filter configurations.
