WinUAE 1.4.2 Public Beta 5 (Emulador Amiga)

Nueva versión beta de este emulador de Amiga para Windows.

Lista de mejoras:

A600/A1200 and A4000 IDE emulation (mount RDB HDF as a IDE drive)

Following IDE harddrive commands emulated (commands that KS ROM require, also IDEFix97 appears to work fine)

Format Track (50, dummy command)

Identify Drive (EC)

Initialize Drive Parameters (91)

Read Sector(s) (20 and 21)

Read Multiple (C4)

Write Sector(s) (30 and 31)

Write Multiple (C5)

Recalibrate (10, dummy command)

Set Multiple Mode (C6)

Set Features (EF, no feature commands supported)


max 2 drives available. "HD Controller"-selection added to GUI.

support statefiles (WARNING: HDF data corruption danger!)

ATAPI (IDE CDROM) emulation not supported (yet?)

Notes: you can't mix Kickstart versions. A4000 KS has only A4000 IDE driver, A600/A1200 KS has only A600/A1200 driver.

Emulated drive is ancient ATA-1 feature level drive, size limits not tested, PIO-0 speed restrictions not emulated

This also means some defaults have been changed. Real IDE without harddrive installed is now enabled if chipset extra is set to A600/A1200 or A4000. Emulated "IDE wire trick" is enabled if no drives installed to prevent long KS boot delay.

Interesting note: A600/A1200 and A4000 KS IDE drivers are totally different, for example A4000 uses LBA addressing but A600/A1200 uses CHS. I don't see the point when the only hardware differences basically are base IO address and different interrupt register..


HRTMon IDE activated if IDE emulation enabled. AR A1200 also works.

68020/68030 + JIT random crashing fixed (b4)

non-3d filters work again (broke in 1.4.2b2)

Agnus/Denise revision settings re-added to advanced chipset

added non-EHB A1000 to Quickstart (not yet in advanced chipset), also added blitter busy bug to A1000 QS if cycle-exact enabled. (busy flag not set until blitter gets first bus access cycle)
