EmuNations

Beta 5

- KS ROM genlock detection still could misdetect genlock in JIT mode causing guru when timer.device attempts TOD calibration and causing non-existing 80000000 guru due to a KS bug (At least KS 3.1, perhaps others too). (6.0)
- Fixed bad drive click code, was semi-broken since the beginning. Sound buffer size affected click sound quality and possibly clicks were missed completely. For some reason some WASAPI devices seem to play empty drive clicks with very low volume and also sometimes play motor sample + clicks strangely (samples are exact same and even volume is same), maybe some noise filter or something done by driver or something?
- Visual DMA debugger now defaults again to Agnus lines, line zero at top. vv-x can be used to show virtual line at top, first line after vsync. Also previously it could have shown random bogus lines at the top or bottom.
- 6.0b1 "If CIA serial port data direction is changed (CRA OUTMODE toggled), serial port state is reset, possible pending transmit or receive is immediately aborted." checked CIA-A vs CIA-B instead of checking if modified control register was A or B. Most likely didn't cause any side-effects, at least with any normal programs.
- Chipset display is now cleared when entering genlock mode without genlock (hsync and vsync stops). Previously last frame was shown until no sync condition ended.
- Trying to load a statefile when in genlock no sync condition didn't do anything.
- ECS/AGA bitplane enable/disable fix when DDFSTRT==DDFSTOP. It always starts bitplane DMA but "ddfstop passed" condition depends on previous state of bitplane logic. Previously it always triggered "ddfstop passed".
- Some ECS/AGA bitplane sequencer mid scanline DMA on/off logic changes, was lost during v5 to v6 update.
- If bitplane DMA last BPL1DAT is also sprite slot and sprite is active: sprite and bitplane DMA conflicts. This was emulated in v5 but was lost during v6 update.
- AVI capture before filtering had swapped color components (6.0)

Beta 4
- OCS/ECS "7-planes" mode didn't enable EHB. (6.0)
- Immediately switch to full line emulation if BPLxDAT is written to, even if line is normally hidden inside vertical blanking (Blanked lines are emulated with simplified code because bitplanes and sprites can be ignored). Unfortunately bitplane data can be visible in some special cases, possibly only during bitplane DMA overrun condition.
- D3D11 fullscreen mode active, enter GUI, switch screen mode to windowed or full-window, press Reset button: windowed mode didn't open, neither did fullscreen mode. Nothing opened. (Very old bug).
- Crash was possible when blanking left/right edges of scanlines, for example when in NTSC mode with NTSC artifacts hidden (b3)
- AlfaPower HD "ROM disabled" option added.

Beta 3
- Fixed fast drawing mode horizontal positioning being wrong randomly (b2)
- NTSC and fast mode and pixel column just before horizontal blank start has changing graphics: single pixel column of garbage was visible (for example NTSC mode + Auto integer scale).
- If whole screen was drawn in fast drawing mode, horizontal bitplane start and end position was not stored, causing horizontal centering, automatic scale etc to fall back to default setting.
- Overscan blanking filter setting didn't allow selecting value -1 (disabled).
- Native/RTG autoswitch is really on by default again.
- Masoboshi Mastercard v2.202 ROM added.

Beta 2
bugs fixed:
- If horizontal centering moved display far enough left to hide part of bitplane, fast mode drawing had horizontal offset. If centering was far enough right, fast mode drawing didn't stop early enough and wrapped around.
- Fixed horizontal centering positioning in programmed/scandoubled modes.
- Added special case for DraCo Altais RTG board: always autoswitch to RTG. DraCo does not have native chipset. (6.0.1 optional autoswitch feature made Altais also optionally autoswitching because Altais does not have built-in switcher. Technically correct but also very annoying with DraCo.)

Other fixes and new features:

- If custom dialog window (HD to HDF creator status bar window possibly was the only one) was closed without user interaction, parent window re-activation was skipped, causing GUI to become completely unresponsive. Old bug.
- Added "Override initial native chipset display" to RTG panel. If set, selected RTG monitor is immediately active at emulator startup, overriding default chipset display. Screen will be blank until RTG board is initialized. Note: if RTG board has built-in switcher and switcher state is changed, switcher state change will override initial monitor selection.
- Masoboshi Mastercard v2.204 ROM (final version) was finally found. Added to ROM scanner. Has same "MASOBOSHI.device (MASOBOSHI MC-702 Treiberprogramm)" device strings but also extra "$VER: MasterCard MC302/MC702 2.204 (29.4.96) by Martin Berndt" at the end of ROM that no other known version have.

EDIT: Fast mode horizontal positioning can be wrong in this beta "randomly" due to use of wrong variable. Will be fixed in next beta.

Beta 1

- Another blitter statesave restore when active fix. If blitter was active when restoring and state was saved with 6.0+, restore might have resumed the blit incorrectly.
- Status bar Power and DFx: had offset when clicking with mouse since capslock/line count was added.
- Add harddrive still didn't work correctly in all situations. (Partition was selected correctly but when emulation started, it didn't find the selected partition anymore). Added some more log messages.
- Configurations that need internal RAM graphics buffer (lightpen cursor, video port adapters including genlock, debugging overlays etc that need to modify output graphics) didn't work correctly in automatic scaling modes (right half of display blanked and possible other side-effects)
- Configurations that need internal RAM graphics buffer (see above) and switching PAL/NTSC (or some other reason for screen height change) didn't update line mapping table, leaving "new" part of display at the bottom blank.
- Autoresolution + NTSC (possibly also in some other display modes) switched between lores and hires continuously.
- Fast line drawing in some situations drew only part of scan line (Pinball Illusions table selection screen or Brilliance II first line of bottom screen)
- Fast line drawing in DPF mode with both planes having different scroll value: visible garbage was possible in right border (Pinball Illusions table selection screen)
- Horizontal centering change sometimes left garbage in edges of screen.
- A2024 and possibly some other display port adapters got broken in 6.0.1.
- On the fly switching to 68000/010 cycle-exact from any non-cycle-exact left internal cycle counter unaligned, causing CE 68000/010 to lose DMA slots "randomly".

Other fixes and new features:

- Added "Always stretch NTSC mode" checkbox to Filter panel (name needs to be better?). If selected (default), NTSC mode is stretched to match PAL mode height. Most filter modes had this active by default. It is now optional. Does not affect Integer scale, most automatic scale and TV modes.
- Paula pot counter increment is clocked by first strobe slot, was still using start of scanline. (As usual, no one cares)
- If GUI has text/numeric edit control active, return only unfocuses the control instead of exiting GUI. Return without focused edit control still exists GUI like previously.
- GUI filter horizontal/vertical number boxes are now directly editable.
- Manual filter mode positioning range increased, previously negative values were not accepted.
- Direct3D 11 mode ignored on the fly fullscreen refresh rate changes.
- External HRTMon ROM images were not accepted. (Maybe some really old ones did work?)
- Gameports remap window didn't always list all mapped input events. Non-listed events still worked correctly.
- Gameports remap and manually adding events with "Add event" button and input source was analog stick movement: remapping "randomly" chose between analog and digital input variant. Now digital variant ([-]/[+] at the end of name) has priority.
- Added 3.2.3 KS ROM checksums (Amiberry)
- If 680x0 CPU is stopped with IPL mask = 7 (CPU can only wake up with NMI or reset), CPU OSD shows CPU as stopped.
- Debugger MMU U command now also outputs MMU table descriptor pointers used for table search. Any debugger MMU command now always first flushes descriptor cache. Previously debugger MMU table searches coud modify MMU tables (for example modified bit would get set if not already set). 68030 MMU mmud full table dump command supported.
- RDB/OFS/FFS hardfile creation option is now separated to RDB and OFS/FFS. RDB adds RDSK identifier to new hardfile and enables Full drive/RDB mode automatically.
- If A2090 or Mast FireBall hardfile is added, RDB mode was not fully activated automatically.
- GUI hardfile "New hard disk image file" section does not anymore reset to defaults after HDF has been created and GUI panel is fully updated after new HDF has been created.
- Added GVP QuikPak (non-XP) 68060 accelerator board. Only has $F00000 ROM that does usual 68060 FPU disable and also adds 9999/22 fake autoconfig device and resident "J Boyer Copyright 1996", no SCSI etc. ROM added to ROM scanner.
- Added Archos Overdrive HD 3.0 ROM ("amiquest.device (IDE 3.0 05/05/93)") ("IDE 5.0 10/02/94" was added long time ago)
- Renamed "SCSI Kit III" and "SCSI Kit IV" -> "Blizzard SCSI Kit III" and "Blizzard SCSI Kit IV" (Rename does not affect existing configurations)
