Winuae 6.0.3 Beta II 01/03/2026

Beta 2: (Possibly final, beta tags removed)

• Fast drawing mode had unreliable long/short field detection in some programmed interlaced modes.

Winuae 6.0.3 Beta I 14/02/2026

Yet another quick 6.0 fix and small update beta series.

NOTE: when reporting, make sure bug was introduced in 6.0.0/6.0.1/6.0.2. If it also happens in 5.3.1 -> create new thread.

6.0.x fixes:

• Fixed DDFSTRT being modified while previous value matched condition, it was not correctly updated when DDFSTRT/STOP logic was rewritten (6020b6). (Display corruption in Back in Bizness / 2000AD, Sly Spy, probably others too)
• Bottom right OCS Denise blanking bug was not visible in Overscan+ mode.
• In some situations fast mode drawing mode generated VB interrupt 1 line too early and also could toggle between correct and incorrect in interlaced modes.
• HIGHGFX SuperHires + interlace screen mode was broken when screen was dragged down 1 more or more pixels in fast drawing modes.
• Display drawing could overflow output buffer by drawing 1 pixel more than fits in the buffer and causing random crashes.
• Switch from RTG to native + fast mode: garbage was randomly possible in right border.
• GUI operations that update the display in realtime (for example Display panel brightness/etc adjustments) caused hang if done before starting. Operations waited for free Denise drawing queue slot without running Denise drawing thread.

Other:

• It is now possible to connect multiple emulated CD drives and use multiple CD images simultaneously. Internally support was mostly done years and years ago but it was never finished.
• Directory filesystem ACTION_CHANGE_MODE responded with ERROR_OBJECT_IN_USE if it was used to change already shared mode file handle or file lock to shared mode.
• Plain HDF with virtual RDB (Plain HDF mounted to emulated HD controller) didn't allow access to last 256k of HDF (wrong virtual HDF offset calculation). Bug probably since virtual RDB support was added. Also return write protected error if trying to write to virtual RDB. Previously writes to virtual RDB were ignored completely.
• If RAM panel memory range is adjusted that is also used for accelerator board RAM: adjust also accelerator RAM size. Expansion panel accelerator RAM to RAM panel copy was already implemented.
• Integer scaling now uses correct aspect ratio when "VGA mode resolution autoswitch" is active.
• If standard output is redirected ("winuae.exe >path/somewhile.txt"), all logging will get redirected. Log console is disabled if redirection is used, redirected output is in utf-8 format.
• -version command line only outputs winuaebootlog.txt "header" lines and then exits.
• If 1G of 32-bit chip ram is enabled: always use UAE Z3 mapping. Hardware info panel before starting emulation now shows correct Z3 board start.
• Internal sound buffer overflowed if WASAPI sound buffer was set to max and channel amount was 6 or more.
• Original X-Surf IDE ports emulated.
• Added Buddha v103.17 ROM to ROM scanner.

After 6.0.3 is out, 6.1.0 beta series will start with more internal rewrites, main changes will be (partially already done in separate branch):

• Copper emulation rewritten to match actual logic gate based state machine.
• Unified native and programmed mode display positioning.
• Display positioning based syncs and blanks (like real displays)
