WinUAE 2.7.1 beta 8

– 68000 CE/prefetch mode reads of non-existing memory should return correct data in all situations.
– Reading of write-only register will now write correct data to register. Data that CPU gets back still isn’t 100% correct (which can be totally different than what was written to register).
– ROM image didn’t load correctly if ROM image was in multiple parts (odd/even) and merged parent ROM was not found.
– NCR SCSI: SCSI commands that failed returned wrong status.
– uaehf.device SCSI Verify (10) implemented. (Does not verify anything)
– A590/A2091 and A4091 options moved to Expansions panel, they are expansions, not built-in features and not part of internal hardware config (advanced chipset). CDTV SCSI is also technicallybuilt-in because driver and DMAC are located on mainboard, CDTV adapter only contains WD SCSI chip.
– A590/A2091 linear ROM mapping was incorrect (Any CPU mode without “more compatible” fetched bad opcode data). Note that A590/A2091 can’t be JIT compatible.
– Added “ROM disabled” option to A590/A2091 ROM select menu. (ROM disable jumper is for 1.2 compatibility)
– It was possible to set and get unused DMACON bits 11 and 12.
– A4091 was not compatible with Z3 Fast.
– Hardcoded A4091 autoconfig data was replaced with data from ROM image.
– Border blank didn’t override AGA border sprites (broke in some previous beta).
– 68020/68030 SR M-bit should be cleared (if set) before executing interrupt routine.
– 68030 MMU FPU FMOVEM instruction continuation state recovery after bus fault was incomplete.
– Generate bus error when accessing invalid memory if A3000/A4000 Fat Gary based system, MMU emulation active and Gary TOENB register bit is set.
– Joystick/joypad can be used to control light pen cursor. (Was mouse only previously)
– Some kind of physical mouse as digital/analog joystick/joypad support. Not that good but perhaps better than nothing.
– Removed useless address space gaps between Z3 boards.
– CD image CDA player may have gotten confused in some situations if new track was requested while other track was still playing.
– 6888x Packed-Decimal Real with Dynamic k-Factor data type was detected as invalid instruction. Allowed now but k-Factor is ignored (Packed-Decimal Real with Static k-Factor was also ignored) but it isn’t that
important, practically no one uses packed decimal data types.
– Some CPU and FPU emulation changes to make it more usable with other emulators (I am working with author of Next emulator Previous to get 68030 based Next computer booting)


Enjoy Life, be kind to others.
