La dernière version béta publique de l’excellent WinUAE, l’émulateur Commodore Amiga.
– Mainboard SCSI controllers didn’t initialize correctly (A3000/A4000T/CDTV) (b12)
– « Do not force full display reset.. » update made it worse, should be better now (b12)
– I finally bothered to carefully re-examine AR3 freezer behavior, emulation updated, should now match real hardware, previously unsupported features like autofire work.
– If copper DMA is switched off mid-instruction, allow instruction to finish. Fixes AR2 weird copper list detection code.
– Added RDB mode HD geometry GUI support. (RDB mode geometry option = what IDE Identify Device and SCSI MODE SENSE Format Parameters/Rigid Disk Geometry returns). Very old controllers may require custom geometry.
– Added HD/CF IDE harddrive GUI option. Currently only difference is in IDE Identify Device word 0 identifier. (Cause for infamous hdtoolbox « Unit is not a disk (Type 7) » error)
– Added GUI IDE and SCSI version selection to hardfile panel. IDE has ATA-1, ATA-2+ (old default, returns ATA-6 to allow LBA48 support and more) and ATA-2+ Strict which drops ATA-1 feature that become optional in ATA-2, triggering A600/A1200/A4000 IDE driver bug that causes infamous « max transfer bug ». (No, it isn’t drive bug) SCSI has SCSI-1 and SCSI-2 options. Currently only real difference is INQUIRY version number, some old software (like original A590/A2091 install disk) require SCSI-1 version.
– Added Archos ADD-500 emulation.
– Added AdSCSI Advantage 2000 emulation.
– Internal enforcer emulation hit can break to debugger, enable/disable with ‘fen’ debugger command.
– SCSI Read Defect Data command: return empty defect header instead of Defect List Not Found error. (ADD-500 driver gets confused if Read Defect Data command does not return any data)
– WD33C93 SCSI devices didn’t support multiple units (b12)
– Added hack that fixes max overscan scrolling in demo Seven Seas / Andromeda. (Demo has workaround for chipset bug that causes right edge to have a vertical gap if BPLCON1 is larger than zero. Hack is currently needed because glitch happens when hpos=0 and emulation is not designed to handle bitplane changes that cross virtual scanlines). Glitch was not emulated until few versions ago, demo worked only accidentally previously.
– Added Windows 10 TP bug workaround, for some reason dialog window is visible before WM_INITDIALOG message (documentation specifically says it won’t be visible until after WM_INITDIALOG) and also dialog is set as not visible. Fixes quickly appearing and disappering empty WinUAE GUI panel each time GUI is opened.
AdSCSI Advantage 2000:
– 5380 based fake DMA.
– First 5380 based driver that uses chip’s arbitrate bit instead of assuming AdSCSI is the only initiator.
– 1.6 ROM added. (Anyone have later? At least 1.9 exists)
– RDB parser is not fully compatible, does not load all filesystems (for example PFS3).
Archos ADD-500:
– Yet another 5380 based fake DMA SCSI controller.
– v1.21 ROM added.
