MiST: FPGA-AGA-Core 1.2

For the Atari/Amiga clone MiST (amiga-news.de reported) an update of the emulated Amiga with AGA-support has been released which further increases the compatibility.



Changes in version 1.2: Initial implementation of programmable display modes

OSD HRTmon enable/disable switch is working (ON – F11 acts as NMI and enters HRTmon; OFF – F11 is HELP key)

Proper handling of CPU access to Chip-RAM & custom regs – CPU waits for free slot when turbo option is disabled

Fixed playfield 2 color LUT offset when playfield 2 has priority for OCS/ECS modes

Some IRQ changes

Added support for undocumented Agnus/Denise behaviour when BPL=7 in ECS/OCS mode (fixes demos like SushiBoyz by Ghostown, Sliced&Diced by Dekadence etc.)

Blitter line mode fixed (fixes demos like SushiBoyz & Sunglasses by Ghostown, Vectorize by RSi etc.)

Bitfield instructions fixed, barrel shifter implemented by Till Harbaum

Fixed colortable for sprites (bplxor) – fixes Alien Breed 3D (and probably many others)

Fixed keyboard rate

Kickstart-ROM is also uploaded to mirror position (E0)

Fixed reset problems & Fast-RAM disappearing

Added CPU CACR cache control, fixed reading CACR reg

Added scanlines for non-doublescan config

Fixed video dithering – both spatial & random dithering weren’t working properly (snx) (Translation: dr)
