Sony Playstation emulator for Windows has been released. Changes:
- cd/help: added notes on sub-cpu mainloop/response/priority/timing/queue/flags
- cd/emu: simplified 1st/2nd/3rd response slots (instead overcomplicated queue)
- debug: optional IRQx logging to tty window (plus detailed cdrom INTxx info)
- cd/emu: emulates exact filter/realtime handling for adpcm and data sectors
- cd/help: added notes on data/adpcm sector filtering/delivery on cdrom-reading
- cd/help: added almost perfect xa-adpcm zig-zag-interpolation formula/tables
- cd/help: added note on unitialized six-step adpcm interpolation counter
- cd/help: added flowchart for using sound map mode (with random 3-slot caution)
- cd/emu: emulates 8bit xa-adpcm decompression (unlike normal 4bit xa-adpcm)
- cd/emu: emulates xa-adpcm zig-zag-interpolation (37.8 to 44.1kHz resampling)
- cd/emu: bugfixed xa-adpcm (did destroy sixstep "extra_offhold" inside of lop)
- cd/emu: emulates newly discovered MotorOn command (and its various errors)
- cd/help: added some basic notes and waveform example for xa-emphasis feature
- cd/emu: emulates invalid xa-adpcm filter=4..15 and invalid shift=13..15 values
- cd/emu: added basic soundmap emulation (works at least to play one 900h unit)
- cd/help: added notes on invalid xa-adpcm filter=4..15 and shift=13..15 values
- spu: bugfixed cd.audio.capture buffer (is NOT affected by cd.audio volume)
- cd/help: added notes on newly discovered secret_unlock feature (command 5xh)
- cd/myth/help: eliminated "Standby" myth (actual function of cmd 7 is MotorOn)
- cd/help: added notes on peak bytes for Play+Report (and incomplete GetQ peak)
- cd/help: added details on purpose/function of all cdrom test commands
- cd/help: discovered more test commands (supported on older PSX consoles only)
- cd/help: added specs for CXA1782BR cdrom servo amplifier registers
- cd/help: added specs for CXD2510Q cdrom signal processor registers
- cd/help: added specs for CXD2545Q cdrom combined servo + signal processor
- cd/help: added specs for CXD1199BQ/CXD1815Q cdrom decoder/fifo registers
- cd/help: added specs for MC68HC05 on-chip I/O Ports (and their usage in psx)
- cd/help: added notes on GetID's ATIP byte, and on POS0 flag in sub_func 21h
- cd/help: removed nonsense sub_function numbers from ancient cdinfo.txt
- cd/help: added info on some formerly unknown CD-XA bytes (in the LEN_SU area)
- cd/help: added subheader CI coding info bits (adpcm emphasis and 8bit/sample)
- cd/help: added notes on more cd-xa fields in primary volume descriptor
- poc/help: added some pocketstation details (LED, mirrors, exceptions, etc)
- help: added notes on PU-7 chipset (different cdrom/spu/gpu/cpu/bios chips)
- bios: added patch_uninstall_early_card_irq_handler_efficient (thanks shendo)
- gui: setup uses asia-compatible TabControl instead of unreliable PropertySheet
- dma3/cdrom and dma6/otc: treats len=0 as length=10000h words (=256 kbytes)
- cdrom data fifo: uses [800h-8] or [924h-4] as padding-byte after sector end
- gui: fullscreen mode preserves real aspect ratio (padded with black border)
- gui: fullscreen mode moved to context menu (instead of old setup option)
- gui: created mouse-shape-less No$helpClass (avoid flickering mouse pointer)
- debug: supports MC68HC05.ROM bios loading (16.5K) (for disasm at 50001000h)
- debug: re-arranged gte registers in iomap (fixed overlapping text fields)
- debug: added dummy-mappings: 50000000h=mc68hc05 memory/mc68hc05 disassembler
- debug: added dummy-mappings: 60000000h=vram, and 70000000h=spu-ram
- debug/help: added disassembler and specs for mc68hc05 cpu (cdrom coprocessor)
- spu/help: corrected spu-irq description (irq9 does trigger also on spu-dma)
- credits: big thanks to psxdev.ru for cdrom 68hc05 sub-cpu decapping
