La dernière version béta publique de l’excellent WinUAE, l’émulateur Commodore Amiga.
– Borderblanking works again (b1)
– RTL8029 received packets got sometimes stuck in receive buffer until next packet was received.
– Fixed PCI bridge unreliable interrupts in some situations.
– Added Mainhattan Data Paradox SCSI emulation.
– Added Spirit Technology HDA-506 HD controller.
– Added Elaborate Bytes A.L.F. HD controller.
– Built-in wave recording created huge files, bytes-to-write variable was never reset (3.1).
– Added Mediator 1200 autoconfig data.
– Added support for multi-function PCI devices.
– Added ES1370 from QEMU. (PCI sound card), common ES1370 based card is SB128.
– Added FM801 emulation. (PCI sound card).
– Added Vortex System 2000 HD controller.
– 68020/030 prefetch/cycle-exact: don’t prefetch from old PC if instruction is going to branch.
– Accelerator board memory size reset when viewing RAM GUI panel if accelerator used « Blizzard » RAM type.
– HD and RTG boards are now named <name> (<manufacturer>).
– A2410 display card emulation! TMS34010 emulation core from MAME.
A2410 notes:
– Very strange display board.. Very flexible TMS34010 CPU on board, code uploaded to internal RAM from Amiga-side. Unfortunately board never had good software support.
– Current WinUAE direct RTG system requires Amiga-side mapped VRAM, but because A2410 does not have any linear mapped Amiga-visible VRAM, A2410 internal VRAM is « fake » mapped at 0xa00000 (normally unused CIA space). It shouldn’t cause any problems.
– Interlaced modes are not supported (Original code didn’t support it all, I added quick hack that doubles height in interlaced modes), either CGX4 driver is wrong or TMS34010 documentation is wrong, documentation says « The size of the DUDATE increment specified for an interlaced display should be twice that required for a noninterlaced display of the same dimensions » but CGX4 driver uses same width value in both interlaced and non-interlaced 1024*768 mode.
– BT458 RAMDAC Overlay bitplanes fully emulated, including blinking features.
– CGX4, Amix, NetBSD console and demo programs from DevCD (Milan 1991 DevCon) confirmed working.
– END+F9 can be used to manually switch between native and A2410 display.
– CGX4 driver seems to have bug in overlay (mouse pointer) color setup routine.
– Emulated Amiga randomly hangs when switching CGX display modes. Reason unknown.
– TMS34010 CPU execution speed is probably totally wrong and very random.
– Because TMS34010 can update any register or RAM data any time it wants (like copper but more flexible), emulation needs to be at least line-based (not frame like other RTG boards) and because emulation also needs to execute TMS34010 code, A2410 emulation is slower than other RTG boards.
– A2410 has DMA and hardware byte swap circuitry (can be seen in schematics) but so far I haven’t found programs that use it. (A2410 DMA = TMS34010 CPU can directly access Amiga address space).
– Must use 32-bit host display depth. 16-bit is not supported.
Mainhattan Data Paradox SCSI:
– Parallel port to SCSI adapter.
– Non autoboot.
– Make sure no other parallel port devices are enabled at the same time.
Spirit Technology HDA-506:
– Supports autoboot but it is not implemented, ROM dump not available.
– OMTI controller, uses early SCSI-like protocol but addressing uses CHS instead of LBA.
Elaborate Bytes A.L.F.:
– Non autoboot.
– MFM/RLL controller.
– Same protocol as HDA-506 but there can be differences in some commands.
Vortex System 2000:
– Supports autoboot but ROM image is not available.
– Non autoconfig, ROM and IO hardwired at 0xf00000.
– Again same protocol as HDA-506.
– Fake DMA, 2xword data port size. Some sites incorrectly lists it as a DMA controller.
