WinUAE 3.4.1 Beta 6 - Comspec SA-1000 SCSI HD controller via Amiga emulation featured


There's no stopping Toni Wilen as once again he's released another Amiga emulator beta update, and this time we are at version WinUAE 3.4.1 Beta 6, which contains even more fixes and improvements including Comspec SA-1000 SCSI HD controller emulation and rare 68040/060 FPU emulation. WinUAE is regarded as the best Amiga emulator for not just games, but it can also be used for emulated or original hardware workbench OS system installs. So if you want the latest updates, check out the changelog below and download!

Beta 6:

- Comspec SA-1000 SCSI HD controller emulation. (Partially implemented only, don't have working install disk)
- California Access Malibu SCSI HD controller emulation.
- Stop immediately with halt code 11 if initial PC does not point to any valid address or is odd when CPU emulator starts.
- Manually configured but disabled (size zero) Z2/Z3 banks were added to system.
- Apollo 1240/1260 memory address space fixed. Memory disable jumper option added.
- 68000 address error stacked PC was not correct in some read-modify-write instructions.
- If Custom board order was enabled, expansion devices custom config setting(s) was not saved correctly.
- Emulate rare 68040/060 FPU (with unimplemented instructions not emulated) fpsp (68040/060.library) software emulation case correctly when both operands are denormals.
- Show [Paused] in windowed mode title bar when in pause mode.
- Transcendental functions added to softfloat emulation (Andreas Grabher). Not 100% identical results compared to 6888x but almost. Softfloat mode is now complete.
- Removed Arithmetic exceptions option, it is now always enabled in softfloat mode. (It was only temporary option until arithmetic exceptions are fully implemented)
- Visual DMA debugger can be switched off, "vo".
- Added visual DMA debugger -5 and -6 modes (-5 = larger overlay with "transparency" and -6 = no "transparency)
- Added separate colors for visual DMA debugger copper wait and special cases (strobe extra cycle, 0xe0 cycle)
- Added visual DMA debugger configuration: DMA channels can be disabled and colors can be changed. "vm" = show status
"vm <channel> <sub index>" = enable/disable toggle. (sub index is not used but must be included)
"vm <channel> <sub index> <hex rgb>" = change color of channel. If sub index is zero: all sub index colors are changed.

Comspec SA-1000:

- Autobooting A1000 HD controller that also supports loading KS disk from HD!
- Not RDB compatible.
- WD33C93 based, PIO, handshake in hardware but still needs status register polling.
- "ComspecHD.device 34.805 (17 Oct 1988)" added to ROM scanner.

California Access Malibu:

- 5380 SCSI, fake DMA (Long word)
- "Malibu.device 1.0 (1 Jan 1991)" added to ROM scanner.
